How to explore Sun Structure 3D Explorer
Open the Sun Structure 3D Explorer, highlight each solar layer, and read core ~15.7 million K, photosphere ~5,772 K, and corona ~1-3 million K in the facts panel.
- Open https://freetoolonline.com/space-3d/sun-structure.html and wait for the cutaway hemispheres and corona halo.
- Read the facts panel: core ~15.7 million K, radiative zone, convective zone, photosphere ~5,772 K, corona.
- Press Core to highlight the fusion region at the center of the schematic.
- Press Radiative or Convective to focus energy-transport layers between core and photosphere.
- Press Photosphere or Corona for ~5,772 K surface and ~1-3 million K outer atmosphere, or All for the full cutaway.

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.
