FEATURES
• Aesthetic views of the planets with realistic details like equatorial bulge and shadows on the rings of Saturn.
• Lots and lots of buttons to press. Fun for kids of all ages!
• You can choose between a drag-and-drop planet-selector and an interface with traditional planetary symbols.
• The facts section includes a wealth of information about planetary atmospheres, orbits, rotations, sizes, densities, gravity, moons and so forth.
• You can decide which units planet properties are displayed in. Centigrade or Kelvin degrees, astronomical units or millions of kilometers …
• You can make side-by-side comparisons of planets and planet characteristics. This will help you make your own AHA! discoveries and learn things that you will remember. Why do Earth’s rotation time and length of day differ? Does that extreme bulge at Saturn’s equator have anything to do with its relatively low density and fast rotation time? …
• You can of course toggle on/off preferences such as music, stars, orbit visualization types …
• You can change the speeds of the rotation and orbit animations. A fun feature for younger children. Watch the inner planets race around the sun!
• Last but not least, educational quizzes for 1-4 players. You select the subjects and which planets to include. Use it at home or in the classroom at school.

We hope you enjoy 8 PLANETS, whether you’re a teacher, student or amateur astronomer. It’s quite different from all of the other solar system apps. It fills an empty niche. We look forward to your feedback which can help us improve and add new features.

Did you guess that the 8 PLANETS logo is based on the traditional symbol for our own planet Earth?

8 PLANETS is designed for Android tablets. It will work fine on your phone, however it looks much better on a larger tablet.
