A ready-made Solar System Explorer UI you can fork, run, and customize with the prompt pack below.
What's actually inside
The honest engineer's breakdown — what the Solar System Explorertemplate does, how it's wired, and where it's opinionated.
Solar System Explorer renders a to-scale (ish) solar system inside an SVG coordinate plane, with each planet orbiting the sun along its own OrbitRing. The orbital animation is driven by Framer Motion's `animate={{ rotate: 360 }}` with `repeat: Infinity` on each OrbitRing — the planet is a child element that stays at a fixed offset from the ring center, so orbital motion comes from the parent's rotation rather than complex position math. This is an elegant approach that avoids trigonometry in the render loop.
StarField provides the background as an SVG layer of `<circle>` elements with subtle CSS twinkle keyframes. SpeedControl is a slider that adjusts the animation duration in real-time using a CSS `--orbit-speed` custom property or by updating Framer Motion transition props. PlanetTooltip appears on click or hover showing planet name, distance, and orbital period data from a local data file. SolarSystemCanvas establishes the full-width coordinate system.
The honest caveats: first, Framer Motion's rotate animation on OrbitRing uses a JS timer, which gets throttled to roughly 1fps when the browser tab is backgrounded. When the user returns, planets jump to wrong positions — the tab-backgrounding gotcha is the most impactful technical insight on this page. Second, this is a portfolio tool, not an orbital simulator — planet positions are aesthetically spaced, not astronomically accurate. Third, click events on fast-orbiting PlanetBody elements are unreliable because the hit target moves constantly.

Fork it and get it running
Forking the Solar System Explorer takes about 10 minutes — slightly longer than simpler templates because verifying the orbit animations and configuring speed controls is worth doing before publishing.
Fork the community template
Open https://v0.dev/chat/community/9tVbNN7zJLX. The community preview shows all planets orbiting in real-time. Click the Fork button in the top-right corner of the preview. V0 creates your own workspace copy of the template in a new chat — no credits are spent on the fork.
You should see: A new V0 chat opens with the solar system code loaded and all planets visibly orbiting in the Preview panel.
Verify all planets animate in orbit
Watch the Preview panel for 10-15 seconds to confirm all OrbitRings are rotating correctly — Mercury should move fastest, outer planets slowest. Try the SpeedControl slider to confirm speed adjustments apply in real-time. If any planet is frozen, reload the preview with the refresh icon inside the panel.
Tip: Switch to another tab for 30 seconds and return — notice whether planets jump to wrong positions. If they do, see the tab-backgrounding gotcha below.
You should see: All planets orbit continuously, SpeedControl changes apply live, and PlanetTooltip appears on hover or click.
Customize planet colors and sizes in Design Mode
Press Option+D (Mac) or Alt+D (Windows) to enter Design Mode. Click on individual PlanetBody elements to change their fill color. You can also adjust the StarField background color from the Themes tab. Design Mode changes cost no credits — use it for all visual-only tweaks before spending credits on structural prompt changes.
Tip: Planet size changes work best via prompt — use 'Add planet name labels' as a quick starting prompt.
You should see: Planet colors and background update in the live preview without any credit cost.
Publish to a live .vercel.app URL
Click Share (top-right), open the Publish tab, and click "Publish to Production". Deployment takes 30–60 seconds. V0 returns a public .vercel.app URL. This URL is ready to share as a portfolio piece, embed in a landing page, or send to clients as an interactive demo.
Tip: The published page is public — no authentication required to view the animation.
You should see: A live URL shows the full interactive solar system to anyone who opens it.
Connect to GitHub for code access
Open the Git panel in V0's left sidebar, click Connect, authorize GitHub, and select a repository. V0 creates a v0/main-{hash} branch and commits all template files. Open the PR in GitHub and merge it. Pull locally if you want to add a NASA data route or touch event support outside V0.
Tip: Advanced data features (NASA Horizons API) require a local environment for server-only env vars.
You should see: A GitHub repo holds the full template code and the v0/main-{hash} branch has been merged to main.
Add a custom domain
In the Vercel Dashboard, select the project V0 created. Go to Settings → Domains → Add. Enter your domain and follow the CNAME DNS instructions Vercel provides. SSL is provisioned automatically. This step is optional for portfolio use but recommended if you're embedding this on a branded space startup page.
You should see: The interactive solar system is accessible at your custom domain with HTTPS.
The prompt pack
Copy-paste these straight into v0's chat to customize the Solar System Explorertemplate. Each one names this template's own components — no generic filler.
Add planet name labels
Adds always-upright planet name labels that track each planet's position without spinning with the orbital rotation.
Render a `<text>` SVG element (or a positioned `<span>` if using div-based OrbitRings) near each PlanetBody showing the planet's name. Use Framer Motion's `useTransform` to apply a counter-rotation so the label stays upright as the OrbitRing rotates — this prevents planet names from spinning with the orbit. Style the labels with Tailwind `text-xs text-white/70` and position them 8px above each PlanetBody.
Add a pause/play toggle for all orbits
Adds a pause/play button that freezes all planets at their current orbital positions and resumes from the same point.
Add a `paused` boolean state initialized to `false`. Pass it as a prop to every OrbitRing component. Inside each OrbitRing, store the current rotation angle in a `useMotionValue`. When `paused` becomes true, animate to `{ rotate: currentAngle }` to freeze in place; when false, resume `{ rotate: 360 }` with `repeat: Infinity`. Render a shadcn/ui `<Button variant="outline">` with a play/pause icon from lucide-react that toggles the `paused` state.Make orbital speed proportional to real-world data
Replaces equal-speed orbits with proportional orbital periods based on real astronomical data, making the simulation educational.
Create a `src/data/planets.ts` file with a typed array of planet objects including `name`, `orbitalPeriodDays` (Mercury: 88, Venus: 225, Earth: 365, Mars: 687, Jupiter: 4333, Saturn: 10759, Uranus: 30687, Neptune: 60190), and `distanceFromSunAU`. In each OrbitRing's Framer Motion `transition`, set `duration = (planet.orbitalPeriodDays / 365) * baseSpeedMultiplier`. Wire the SpeedControl slider to adjust `baseSpeedMultiplier` between 0.1 and 10 so Jupiter orbits roughly 12x slower than Earth at any speed setting.
Show planet info panel on click
Converts PlanetTooltip into a stable side panel that slides in with planet details when the user clicks any planet, avoiding the moving-target click problem.
When a PlanetBody is clicked, set a `selectedPlanet` state to that planet's data object. Render PlanetTooltip as a fixed side panel on the right edge of the page (not a popover — a stable panel doesn't chase the moving planet). Include: planet name as a heading, diameter in km, distance from Sun in AU, number of moons, and a one-sentence fun fact. Wrap the panel in `AnimatePresence` with a slide-in from the right: `initial={{ x: 300, opacity: 0 }} animate={{ x: 0, opacity: 1 }}`. Add a close button.Fetch live planet positions from a NASA Horizons API route
Replaces hardcoded orbital positions with live ephemeris data from NASA's public API, making positions accurate to the current date and time.
Create `app/api/planets/route.ts` that calls the NASA JPL Horizons system API at `https://ssd.jpl.nasa.gov/api/horizons.api` for real ephemeris data for each planet. Map the returned RA/Dec coordinates to SVG x/y positions within SolarSystemCanvas bounds. Store your `NASA_API_KEY` as a server-only env var in V0's Vars panel (no NEXT_PUBLIC_ prefix — this key must never reach the browser). In the client SolarSystemCanvas component, use a `useSWR('/api/planets', fetcher)` hook with a 60-second `refreshInterval` to poll the route and update planet positions dynamically.Gotchas when you extend it
The failures people actually hit when they push this template past its defaults — and the exact fix for each.
Planets drift off their orbits after tab switch or long idleWhy: Framer Motion's `animate={{ rotate: 360, repeat: Infinity }}` uses a JavaScript timer. When the browser tab is backgrounded, the timer throttles to ~1fps. On resume, the animation restarts from a phase that doesn't match where it left off, causing planets to jump.
Fix: Switch to CSS `animation` with `@keyframes rotate` for the OrbitRing rotation. CSS animations are GPU-composited and handled by the browser's compositor thread, which survives tab backgrounding correctly. Framer Motion can still be used for entrance animations and hover effects on other elements.
Replace Framer Motion's rotate animation on OrbitRing with a CSS keyframe animation using `animation: orbit linear infinite` so it survives tab background throttling
`window is not defined` when SVG dimensions use window.innerWidthWhy: SolarSystemCanvas reads viewport dimensions using window.innerWidth or window.innerHeight to size the SVG coordinate plane. This code runs during SSR in Next.js App Router where the window object doesn't exist.
Fix: Replace JS-computed pixel dimensions with CSS sizing: `width: 100%; height: 100vh` on the SVG or container div. If you need JS measurements, guard all window references with `typeof window !== 'undefined'` and move them into a useEffect hook.
Replace window.innerWidth with a CSS container query or useEffect-guarded measurement to prevent SSR errors
PlanetTooltip clicks unregistered during fast orbit animationsWhy: A fast-orbiting motion.div has a constantly changing bounding box. Pointer events fire on the element, but by the time the browser processes the event, the hit target has already moved — clicks appear to miss.
Fix: Place a static invisible circular click-target at each planet's orbital center (the sun), not on the animated PlanetBody itself. Handle click events on this static overlay and identify which planet was clicked by data attribute. The 'Show planet info panel on click' prompt above builds this pattern.
Add a static invisible click-target element at each planet's orbit center and handle clicks there instead of on the animated PlanetBody
Tailwind CSS v3/v4 conflict breaks the star field backgroundWhy: The StarField uses `bg-[radial-gradient(...)]` arbitrary value syntax, which changed between Tailwind v3 and v4. Pulling the template into a create-next-app project (which defaults to Tailwind v4) can break the star background silently.
Fix: Replace the arbitrary gradient Tailwind class with a CSS custom property defined in globals.css. Set `--star-bg: radial-gradient(...)` and apply it via `style={{ background: 'var(--star-bg)' }}` on the SolarSystemCanvas wrapper. This works identically in both Tailwind versions.
Replace Tailwind arbitrary gradient syntax with a CSS variable in globals.css to avoid v3/v4 incompatibility
Template vs. custom — the honest call
A forked template gets you far, fast. Here's where it holds up, and where you'll outgrow it.
The template is enough when
- You want an interactive, visually impressive solar system for a science education site, space startup landing page, or portfolio demo
- Animation speed and planet data are your only customization needs
- You need to ship in hours, not days, and visual polish matters more than orbital accuracy
- You want a working reference for Framer Motion infinite rotation loops and CSS custom property integration
Go custom when
- You need true 3D rendering with WebGL (React Three Fiber) for realistic sphere shading and depth
- You need real-time accurate ephemeris data synchronized to actual celestial positions throughout the day
- You need VR/AR integration or mobile gyroscope-based interaction
RapidDev can extend this to a full interactive space explorer with real NASA data feeds, mobile touch controls, and production-grade performance tuning.
Frequently asked questions
Is this solar system template free to use?
Yes. V0 community templates are free to fork with a V0 account (free tier available). The generated code is yours with no usage restrictions.
Can I use this template commercially?
Yes. V0 community template code has no commercial use restrictions. It's suitable for client projects, startup landing pages, educational platforms, or any commercial use.
Why does my fork break in preview — planets don't orbit?
The most common cause is the V0 preview sandbox taking a moment to warm up for complex SVG animation templates. Click the refresh icon inside the Preview panel and wait 10-15 seconds. If planets are still frozen, try a small prompt change (like 'add a comment to the OrbitRing component') to trigger a fresh render.
Why do planets jump to wrong positions when I switch tabs?
Framer Motion's JS-based rotation timer is throttled when tabs are backgrounded. When you return, the animation restarts from the wrong phase. The fix is to switch OrbitRing to a CSS keyframe animation — see the 'Planets drift off their orbits' gotcha above for the exact fix prompt.
Is the solar system astronomically accurate?
No. Planet positions are aesthetically spaced for visual balance, not orbital accuracy. The 'Make orbital speed proportional to real-world data' prompt makes speeds proportional to actual orbital periods, and the NASA Horizons advanced prompt adds real ephemeris positions — but the basic template is a visual demo, not a simulator.
How do I add more planets or custom moons?
Add a new object to the planets data array with the planet's name, orbital radius, speed, and color, then create a corresponding OrbitRing and PlanetBody pair. For moons, nest a smaller OrbitRing and PlanetBody inside an existing PlanetBody — the counter-rotation for labels prompt gives a good pattern to build from.
Can I connect this to real NASA data?
Yes — the 'Fetch live planet positions from a NASA Horizons API route' prompt in the prompt pack gives you the complete setup: an App Router route handler calling the NASA JPL Horizons API, server-side key storage in V0's Vars panel, and a SWR polling hook on the client.
