How to Use the Rogue Planets 3D Explorer - Step by Step

Last reviewed: 2026-08-30

Open the Rogue Planets 3D Explorer, pick a lens mass, and press "Play event" to watch a background star briefly brighten - with no host star anywhere in the scene.

Pick a lens mass

Press "Sun-like star", "Jupiter-mass planet", or "Earth-mass planet" to switch the lens mass. The facts panel updates with the real published event duration for that mass class - weeks for a star, hours for a Jupiter-mass planet, and just 41.5 minutes for the real record-holder, OGLE-2016-BLG-1928.

Play or scrub the event

Press "Play event" to watch one full brightening pass, or drag the event-progress slider to hold any moment. The light-curve canvas below the scene traces the exact brightness shape at that moment, with a red marker showing your current position.

Reveal the invisible lens

Press "Show inferred path" to add a dark marker and a faint dashed line showing where the rogue planet is passing. This is a teaching aid only - by default nothing marks the lens, matching what a real telescope actually sees.

Compare the two population estimates

Press "Showing: 2011 estimate" to flip the facts panel to the 2017 revision and back. The two numbers are both real, published results - not one settled figure.

Drag to orbit and use fullscreen

Drag to orbit the camera around the starfield, scroll or pinch to zoom, and use the Fullscreen button to expand the whole wrapper for a clearer view.

Next: see when to use this explorer or how it compares to the Gravitational Microlensing Exoplanet 3D Explorer.

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.
