Star Walk is an educational astronomy application developed by Vito Technology that allows users to explore celestial objects in real time through the screen of their devices. The application is presented in the mobile software market since 2001 and is available for iOS, Android and Windows. Since its release Star Walk has been downloaded by more than 10 million users around the world.[1]

The objective of Star Walk is to help astronomy amateurs, students and professionals locate and identify over 200,000 stars, planets, constellations and satellites in the night sky, providing detailed information about them.


Time Machine will help users explore the map of the night sky of tomorrow or years ago.

The application helps to determine the exact position of celestial objects in the sky above. It also includes extra information on star clusters, meteor showers, iridium flares, galaxies and nebulas along with the current position of dwarf planets, comets, asteroids and man-made satellites.[2]

Star Walk also provides a single-screen space dashboard, showing you when the Sun (and potentially visible planets) rises and sets at your location, along with the current moon phase, elevation angle, and day length.

Star Walk shows users a list of upcoming celestial events which they can add to the calendar and set a reminder for.

Also, the application is equipped with time machine feature which gives an opportunity to rewind or fast-forward time to explore the map of the night sky in the past and future. Besides, Star Walk uses iOS device camera for augmented reality feature. It combines the image data from camera with the star map to give the user a real time view of celestial objects.[3]

Star Walk 2[edit]

Star Walk 2 is a solid update from the original Star Walk astronomy application. This new version has a re-designed interface and offers a variety of camera modes: free roam, scroll/manual, and augmented reality. The augmented reality view remains as a holdover from the original app.[4] In order to explore the night sky objects, the user can orient the device toward the sky so that the application activates the camera and the charted objects can be seen appearing superimposed on live sky objects.

Users can scroll a list of objects visible on any night and from any location on Earth. Tapping on an object name displays pop-ups that give you information on the object, a Wikipedia link for more details, and a 3D option if there is one for that item.

Star Walk 2 app also has a "What's New" feed of the latest astronomy news.

The developer offers an ad-free version for $2.99 with expansions that adds deep sky objects, satellites etc. for $0.99 each.[5]
