Planets is a nice 3D viewer that allows you to explore the planets of our Solar System in high resolution. The Great Red Spot on Jupiter, the beautiful rings of Saturn, the mysterious structures of the Pluto's surface, the impact craters and the polar ice caps of Mars, all of these cosmic wonders can now be seen in great detail. This app is mainly designed for tablets, but it works fine on the modern phones too (Android 4 or newer). There are some limitations in this version of Planets - Save, Screenshots and all the Moons are disabled (they are Pro features) - and the application works only two minutes per run.
-- you can zoom in, zoom out or rotate any planet, as you like
-- the auto-rotate function simulates the natural motion of planets
-- basic information for each celestial body (mass, gravity, size etc.)
-- accurate ring models for Saturn and Uranus
