When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle, and a solid crust.
2 giorni fa · Mars is designated by the symbol ♂. Sometimes called the Red Planet, Mars has long been associated with warfare and slaughter. It is named for the Roman god of war.

Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to explore the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago. Explore with Us
The geological history of Mars follows the physical evolution of Mars as substantiated by observations, indirect and direct measurements, and various inference techniques.
1 set 2019 · The geological history of Mars has been divided into three main periods, each named after a region of Mars: Noachian, Hesperian, and Amazonian. An earlier, Pre-Noachian, period has also been identified, even though no physical evidence for its existence remains.
