However, in terms of their sidereal rotation (time it takes for the planet to complete a single rotation on its axis) Earth and Mars are again in the same boat. While Earth takesprecisely 23h 56m and 4 s to complete a single sidereal rotation (0.997 Earth days), Mars does the same i...
The rusty world is full of mysteries—and some of the solar system's most extreme geology. Learn more about Earth's smaller, colder neighbor.

These Doppler measurements will be used to obtain Mars' orientation in space and rotation (precession and nutations, and length-of-day variations). More specifically, the relative position of the lander on the surface of Mars with respect to the Earth ground stations allows reconstructing Mars' ...

Like Earth, Mars rotates on its axis from west to east. A solar day is the length of time a planet takes to turn around once with respect to the Sun. The Martian solar day, sometimes called asol, is 24 hours 39 minutes 35 seconds long, slightly longer than Earth's solar day of 24...
The planet'scold, thin atmospheremeans liquid water likely cannot exist on the Martian surface for any appreciable length of time. Features called recurring slope lineae may have spurts of briny water flowing on the surface, but this evidence is disputed; some scientists argue the hydrogen spotted...
The Rotation of the Earth Students continued to understand how our Solar System operates, beginning with how each planet orbits our Sun in an anti-clockwise direction. Students also learned about how day and night exist through the Earth rotating on its axis....
rotation is called asol. The planet's axis is tilted by 25.19° to its orbital plane. The rotation rate and axial tilt help to make the Red Planet the most earthlike of all the other planets, even though it has only 28% of the Earth's surface area and less than 38% of its ...
The large canyon, Valles Marineris (Latin for Mariner Valleys, also known as Agathadaemon in the old canal maps), has a length of 4,000 km and a depth of up to 7 km. The length of Valles Marineris is equivalent to the length of Europe and extends across one-fifth the circumference of...
