A free program for Android, by Cass Everitt.
This application can help you to track the location of various celestial bodies, like planets, stars, and even satellites. The application displays the current location of the object, its coordinates on the sky, as well as its current distance from the Earth. This makes it very easy to find the location of any object in the sky, even if it is far away from you.
You can use the app to find out what is currently in the sky, which bodies of the Solar System are currently visible to you, and even what is currently the furthest away from the Earth.
