Copernican Orrery / Description

A Copernican-style Orrery showing the positions of the 8 planets and their primary moons as well as our moon's phase.



The Orrery is a model of the solar system as view from celestial north and orientated
such that solstices occur when the earth is due-north (top winter solstice) or
south (bottom summer solstice) and the equinoxes are east (right autumnal equinox)
and west (left vernal equinox). All orbits are assumed to be perfect circles.



The position of the Earth and Moon are fairly accurate as are their orbits. The remaining planets positions are approximate but close enough considering the size of the typical phone or tablet screen. The starting positions of the moons other than that of the Earth is not accurate. The orbital periods of all planets and moons is accurate relative to the other planets and moons.



This app should be considered simply something fun to look at but not anything to be taken too seriously.
