    Orrery at time of earthquake

    The Orrery gives the position of the planets at the time of the earthquake, and the ephemeris has been set for the latitude and longitude of the event. The ephemeris shows you the positions of the principal bodies in the Solar System at the selected time, both in celestial coordinates and as seen from the event epicentre.
