How Stargazer Works

01

Source

JPL HORIZONS for orbits. Celestrak for TLEs. wheretheiss.at for ISS. All public, all free.

02

Compute

Standish/Meeus for planets. Keplerian solver for moons. SGP4 for satellites. All client-side.

03

Render

Real axial tilts, real rotation, Saturn rings at correct radii. Compromises disclosed.

04

Verify

Every panel shows the real numbers. Cross-check against JPL, timeanddate.com, or Stellarium.

Free · Open source · No account required

Click anything in space

Fly to Voyager 1 in interstellar space, watch the Galilean moons orbit Jupiter, see Curiosity sitting in Gale crater. Free, open source, and runs in any modern browser.
