Rogue Planets 3D Explorer vs Gravitational Microlensing Exoplanet 3D Explorer
freetoolonline.com editorial teamBoth pages render the same real microlensing physics in one page load - 0 MB installed, USD 0, no account. The Rogue Planets 3D Explorer covers a planet with NO host star at all; the Gravitational Microlensing Exoplanet 3D Explorer covers a planet still orbiting a visible lens star.
The numbers side by side
| Aspect | Rogue Planets Explorer | Microlensing Exoplanet Explorer |
|---|---|---|
| Install size | 0 MB - runs in the browser | 0 MB - runs in the browser |
| Price | USD 0 | USD 0 |
| Host star | None - the planet itself is the entire lens | Visible - the planet orbits it |
| What's short | The whole event: 41.5 min for the record case (OGLE-2016-BLG-1928) | Only the secondary spike; the main event still lasts weeks |
| Core figure shown | ~1.8 vs ~0.25 free-floating planets per star (2011 vs 2017) | ~20-40 day typical event; hours-to-days planet spike |
| Main control | Mass-preset buttons changing the event-duration text and curve width | Planet on/off toggle adding a secondary spike |
Where the Microlensing Exoplanet Explorer wins
The Microlensing Exoplanet Explorer wins when the question is a planet that still orbits a star - it shows the visible lens star, the ring, and the short secondary spike a real orbiting planet adds to that star's own multi-week brightening curve.
Where the Rogue Planets Explorer wins
The Rogue Planets Explorer wins when the question is a planet with no host star at all - why the entire event is short rather than just a spike, why the lens itself is never directly visible, and how the 2011 population estimate compares to the 2017 revision that lowered it.
A reasonable rule
As a reasonable rule, use the Microlensing Exoplanet Explorer first to see the general single-lens brightening shape and how an orbiting planet adds to it, then use the Rogue Planets Explorer to see what changes when there is no host star to add anything to.

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
