Watch Stars Online with Planetarium Chrome Web App

Planetarium is an interactive star map, customizable by location (latitude and longitude) and time of day. You can explore the stars and planets using the Planetarium web app.

You can simply lick and move your mouse to look around the sky, or point at a star or planet to reveal its name, its constellation, its brightness (magnitude) and how far away it is in light years (LY) or astronomical units (AU). You can also adjust the time and your viewing location to see the sky from any point around the world.

Planetarium has around 1500 stars – every star up to magnitude +5. These stars are the brightest in the night sky, the ones you can see with your own naked eye on a good dark night away from city lights.

Happy star gazing!
