Asteria Coeli

Asteria Coeli for Android is not a planetarium simulator and not a game, but a sky atlas designed analog to a paper atlas for the purpose of looking up sky positions of celestial objects. The primary purpose is for learning about astronomy. The electronic form takes advantage of zooming and selection of features to be displayed or not -- possibilities which are not available to paper.

The star chart is plotted on equatorial coordinates centered on a selected object of interest. A star chart can be saved to external memory card for documentation purposes, such as for printing, websites or blogs. For this purpose, a monochrome (white background) display is provided.

Asteria Coeli adds an interactive planisphere view including stars, constellations, sun, moon, planets and comets, plus Sun and Moon information, such as rise & set and ephemerides.

Global 3D surface views are available for solar system planets as is a fully fledged interactive moon calendar, a moon atlas, and sun path plot.

An abundant and partly illustrated astronomy quiz has been added for those eager to learn about astronomy the easy way. To provide some help, the quiz offers two means of assistance, a 50/50 narrow-down or a hint button.

Asteria Coeli is strongly recommended for tablets or phones running Android 3+ with screens larger than 5 inches across.
