Real Time Solar System

Positions are computed from VSOP87 and an ELP-derived lunar theory, accurate to within one arcminute. Nothing here is an animation on a timer: every body is where it actually is.

How accurate is this

Planet positions come from VSOP87 and the Moon from an ELP-derived series, both validated against NOVAS and JPL Horizons to within one arcminute. Eclipse and phase times are exact to the minute. This is not suitable for navigation or spacecraft operations.
