Mars has an axial tilt of 25.19°, quite close to the value of 23.44° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times. However, the orbit of Mars has significantly greater eccentricity than that of Earth. Therefore ...
Like Earth, Mars is differentiated into a dense metallic core overlaid by less dense rocky layers. [ 45 ] [ 46 ] The outermost layer is the crust, which is on average about 42–56 kilometres (26–35 mi) thick, [ 47 ] with a minimum thickness of 6 kilometres (3.7 mi) in Isidis Planitia , and a maximum thickness of 117 kilometres (73 mi) in the ...

The study of extraterrestrial atmospheres is an active field of research, [1] both as an aspect of astronomy and to gain insight into Earth's atmosphere. [2] In addition to Earth, many of the other astronomical objects in the Solar System have atmospheres. These include all the giant planets, as well as Mars, Venus and Titan.
It’s a term used by astronomers to describe when Earth, Mars and the Sun align. When this happens, Earth sits directly between Mars and the Sun, positioning the red planet directly opposite of ...
