Approximate catalog distances. Earth and the Sun share the origin at stellar scale; in the solar view, Earth orbits about 1 AU from the Sun. Choose Solar system to explore the planets. Planet orbits use approximate J2000 elements; bodies are enlarged and time is accelerated, not a live ephemeris.

Choose a constellation to see its familiar pattern from near the Sun. Guide lines connect stars at their real catalog distances, not physical structures or IAU boundaries. Patterns change with viewpoint. The Big Dipper is an asterism within Ursa Major.
