Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
The zodiac constellations of Mars's ecliptic are almost the same as those of Earth — after all, the two ecliptic planes only have a mutual inclination of 1.85° — but on Mars, the Sun spends 6 days in the constellation Cetus, leaving and re-entering Pisces as it does so, making a total of 14 zodiacal constellations.
The average length of a Martian sidereal day is 24 h 37 m 22.663 s (88,642.663 seconds based on SI units), and the length of its solar day is 24 h 39 m 35.244 s (88,775.244 seconds). [3]
Mars isn’t the only planet to keep an eye out for this month. Sky-gazers can look forward to catching glimpses of four bright planets at the same time in the night sky.
The average duration of the day-night cycle on Mars — i.e., a Martian day — is 24 hours, 39 minutes and 35.244 seconds, [3] equivalent to 1.02749125 Earth days. [4] The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 minutes and 22.66 seconds. [4]
Certain areas of Mars develop clouds at night that drop icy rain rather quickly -- and in some areas, perhaps snow. While neither have been strictly observed, researchers have developed new ...
And we're about to witness Mars reaching opposition in 2025. Even though we can’t hop into a rocket and fly into the galaxy, luckily there are moments when the planets seem to reach out to us ...
