Solar Explorer

Tour the Solar System, one world at a time.

Choose a planet, then launch. No downloads and no sign-up; it runs right here in your browser.

Solar Explorer turns the Solar System into a place you can explore. You command the SES Horizon, leaving Earth to visit ten destinations, from the blazing Sun to distant, icy Pluto. Visit and learn about each world, on a phone, tablet, or desktop.

Play big: fullscreen mode

For the most immersive view, switch the game to fullscreen so it fills your whole screen, much like an app.

To enter fullscreen
Tap the fullscreen button in the top instrument bar (the icon with four arrows pointing outward), or press the F key if you are using a keyboard.
To exit fullscreen
Tap the same button again (it then shows four arrows pointing inward), press F a second time, or press the Esc key.

Fullscreen works on phones, tablets, and computers. On a touchscreen, use the button, since there is no keyboard shortcut.
