The sky from Mars
Stand on the Martian surface and look up. The Sun is noticeably smaller and dimmer than from Earth. Our own planet shrinks to a pale-blue morning or evening "star," while the familiar constellations wheel overhead, every one of them positioned for the exact date and time you set.
A real planetarium, not a backdrop
Nothing in the surface view is a painted skybox. Constellations, the Milky Way, deep-sky objects, the Sun, Moon and planets are all placed with the astronomy-engine library, built on JPL ephemerides. Change the date, the time or where you're standing and the whole sky responds.
FAQ
What does the sky look like from Mars?
A smaller, dimmer Sun, a distant Earth reduced to a bright "star," and the real constellations, for any date and time.
Can I stand on the Moon?
Yes. You get a first-person lunar sky with Earth overhead, correct for your chosen date and location.
Is the sky accurate?
Yes. Positions use astronomy-engine (JPL ephemerides), so everything appears where it really would.
Is it free?
Yes. In your browser, no account, no download.
