About

Star Atlas is an interactive star map of the night sky — a virtual, online planetarium, created by Neave Interactive.

Over 60,000 stars, up to magnitude 8.5, are available to explore. Simply click and drag the sky to look around, and click a star or planet to find out more. Zoom using two fingers on a trackpad, or using a mouse scroll wheel.

For updates on new features in Star Atlas you should follow on Twitter or Instagram.
