Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Phobos is Mars's inner moon. It is a small, irregularly shaped object with a mean radius of 11 km (7 mi). Its surface is very unreflective and dominated by impact craters. [D 7] [125] In particular, Phobos's surface has a very large Stickney impact crater that is roughly 4.5 km (2.8 mi) in radius. [126] Deimos is Mars's outer moon. Like Phobos ...
The Perseverance rover has found evidence in a leopard-spotted rock that could suggest microbial life once existed on Mars billions of years ago, NASA said. NASA’s Perseverance rover may have ...
These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe. [135] [138] [139] [136] [133] [140] PC 1247–3406: Quasar 1991 − ...
The Noachian period occurred from 4.1 to 3.7 billion years ago, and little is known from direct measurements dating to the pre-Noachian period on Mars, between 4.5 billion and 4.1 billion years ...
As of 2022, three bodies in the Solar System, the Moon, Mars and Ryugu [71] have been visited by mobile rovers. The first robotic rover to visit another celestial body was the Soviet Lunokhod 1, which landed on the Moon in 1970. The first to visit another planet was Sojourner, which
Among the highest nonvolcanic peaks on Mars, formed by the Hellas impact: Aeolis Mons ("Mount Sharp") 4.5 to 5.5 km (2.8 to 3.4 mi) [29] [n 7] 0.16: deposition and erosion [n 8] Formed from deposits in Gale crater; [34] the MSL rover has been ascending it since November 2014.
