Features & Capabilities

The Comet Book app clearly shows when Comets can be viewed and in which direction. The direction and elevation of a Comet can change noticeably in a day due to its fast apparent motion. The moon and a bright planet may be convenient as a guide to find the comet though they have large apparent motion, too.

This app determines where Comet is in the sky when it becomes visible at your observing site. You can easily start your observation of a Comet by using Comet Book as a guide to the direction and elevation of the comet.

In addition, the new “3D Solar System seen from Space” mode allows you to view the motion of Comets and planets turning around the sun. Please take a look the comet’s movement around our solar system.

User Reviews

Nice and simple interaction design allowing the user to understand from different perspectives.

This one of the very few comet finder apps and it even provides a 3d orbit view. It's difficult to find in the English app store, maybe due to a few Japanese symbols still used in the app?
