3 dni temu · Mars has ice caps at its north pole and south pole, which consist mainly of water ice; however, there is frozen carbon dioxide present on their surfaces. Dry ice accumulates in the north polar region ( Planum Boreum ) in winter only, subliming completely in summer, while the south polar region additionally has a permanent dry ice cover up to ...
1 dzień temu · Mars is the fourth planet in the solar system in order of distance from the Sun and the seventh in size and mass. It is a periodically conspicuous reddish object in the night sky. There are intriguing clues that billions of years ago Mars was even more Earth-like than today.
3 dni temu · It moves around the Sun at a mean distance of 228 million km (140 million miles), or about 1.5 times the distance of Earth from the Sun. Because of Mars’s relatively elongated orbit, the distance between Mars and the Sun varies from 206.6 million to 249.2 million km (128.4 million to 154.8 million miles).
