How to Explore Hohmann Transfer 3D Explorer - Step by Step
The Hohmann Transfer 3D Explorer starts as soon as the page loads: drag to orbit the view, scroll or pinch to zoom, and press Play transfer to fire both burns. Everything renders on your own device - no install, no account.
Open the scene
Load the page and the LEO to GEO preset appears by default, with the craft resting on the inner orbit ring. The 3D engine downloads once and is cached. If WebGL is unavailable, a plain notice appears instead of a broken canvas, and the facts panel still reads normally.
Pick a preset
Press LEO to GEO for the satellite-scale transfer (r1=6,678 km, r2=42,164 km) or Earth to Mars for the interplanetary transfer (r1=1.0 AU, r2=1.524 AU). Each preset redraws the inner and outer orbit rings, the transfer ellipse, and the facts panel together.
Fire the transfer
Press Play transfer. The button relabels to Transferring while the craft coasts the teal ellipse from the teal departure marker to the orange arrival marker over about three seconds of animation - representing exactly half the real transfer orbit. When it arrives, the button relabels to Reset to inner orbit.
Check a single burn
Click the teal marker on its own for the departure burn's delta-v, or the orange marker for the arrival burn's delta-v. For LEO to GEO these are 2.45 km/s and 1.47 km/s; for Earth to Mars the published figure covers the whole maneuver rather than a clean per-burn split.
Read the facts panel
The panel lists the inner orbit radius r1, outer orbit radius r2, transfer time, and total delta-v for the active preset, plus a note on how the transfer-time figure was sourced or computed. A closing note states that on-screen orbit radii are compressed for readability while the r1, r2, time, and delta-v figures are real.
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.
