Earth
The only planet where the ephemeris is computed from inside the object.
Where it is right now
Earth is underfoot, 1.015 AU from the Sun.
Computed for 2 August 2026, 17:00 UTC, and recomputed at least hourly. This page is cached, so treat the line above as accurate to the hour rather than to the second. The map shows the live position.
Position from astronomy-engine's VSOP87-derived series, accurate to about an arcsecond.
