Planets positions and distances - Ephemeris
Welcome to the Ephemeris page, where you can view current and past/future positions of planets in the solar system on a specific date.
This section also provides interplanetary distances, based on heliocentric coordinates.
Data accuracy
The data comes from internal calculations based on digital ephemeris, with an error margin of less than 0.01 AU.
