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.
Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
Yogi Rock, analyzed by the Sojourner rover (July 4, 1997). The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust. [1] From close up, it looks more of a butterscotch, [1] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.

Unlike Earth, Mars does not have a global magnetic field to protect its atmosphere, leaving it vulnerable to solar ultraviolet radiation. Scientists crack mystery of Mars' missing atmosphere ...
The maximum angular separation of the Earth and Moon varies considerably according to the relative distance between the Earth and Mars: it is about 25′ when Earth is closest to Mars (near inferior conjunction) but only about 3.5′ when the Earth is farthest from Mars (near superior conjunction). For comparison, the apparent diameter of the ...
The origins of the planetary symbols can be found in the attributes given to classical deities. The Roman planisphere of Bianchini (2nd century, currently in the Louvre, inv. Ma 540) [2] shows the seven planets represented by portraits of the seven corresponding gods, each a bust with a halo and an iconic object or dress, as follows: Mercury has a caduceus and a winged cap; Venus has a ...
