When to Use the Yarkovsky Effect 3D Explorer - Best Sessions and Limits

Last reviewed: 2026-07-23

Open Yarkovsky Effect 3D Explorer when you want to see why asteroid Bennu's measured orbit is slowly shrinking, or to teach the general prograde-grows / retrograde-shrinks rule side by side - not to run a to-scale orbital-dynamics propagation or watch a live tracking feed.

A prograde-vs-retrograde lesson

A lesson starts on Retrograde (Bennu, measured) and scrubs the elapsed-years slider to 100 to see the orbit ring shrink and the cumulative-drift readout grow negative, then switches to Prograde (teaching mirror) and repeats the scrub to see the same magnitude drive the orbit outward instead.

Sessions this explorer does not fit

Sessions this page does not fit are running an impulsive gravity-assist maneuver - use the Gravitational Slingshot 3D Explorer for that - or checking a tidal-disruption boundary - use the Roche Limit 3D Explorer. Walk the controls in the step-by-step guide.

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.
