Description

From the listing uploaded by “advancedmaiky”.

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.

Copernican Orrery APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Copernican Orrery APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is e6f0020d1437c3f615ee4f6664716b31.
