The sky from Mars
From Mars, the Sun looks smaller and Earth becomes a pale blue point near dawn or dusk. The constellations remain familiar, but their positions change with the Martian location and time you choose.
The sky updates with the clock
Astronomy Engine places the Sun, Moon, planets, constellations, and deep-sky objects using JPL ephemeris data. Change the date, time, or location and the view updates.
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.
