The lowest elevations on the planet are located within the Hellas basin, with some areas of the basin floor lying over 8 km below datum. [34] The two other large impact structures on the planet are the Argyre and Isidis basins. Like Hellas, Argyre (800 km in diameter) is located in the southern highlands and is surrounded by a broad ring of ...

Even if the terrestrial planets had had hydrogen and helium, the Sun would have heated the gases and caused them to escape. [3] Hence, solar terrestrial planets such as Mercury, Venus, Earth, and Mars are dense, small planets composed mostly from 2% of heavier elements contained in the solar nebula.
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. "Hottah" rock outcrop on Mars – ancient streambed [1] [2] [3] viewed by the Curiosity Rover (September 12, 2012, white balanced) (raw, close-up, 3-D version). Abundant iron compounds are responsible for the bright brownish-red ...
Mars is a terrestrial planet with a surface that consists of minerals containing silicon and oxygen, metals, and other elements that typically make up rock. The Martian surface is primarily composed of tholeiitic basalt , [ 59 ] although parts are more silica -rich than typical basalt and may be similar to andesitic rocks on Earth, or silica glass.
Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...

The magnetic field of Mars is the magnetic field generated from Mars's interior. Today, Mars does not have a global magnetic field. However, Mars did power an early dynamo that produced a strong magnetic field 4 billion years ago, comparable to Earth's present surface field. After the early dynamo ceased, a weak late dynamo was reactivated (or ...
