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.
In English, the planet Mars is named after Mars, the Roman god of war, [1] an association made because of its red color, which suggests blood. [2] The adjectival form of Latin Mars is Martius, [3] from which the English word Martian derives, used as an adjective or for a putative inhabitant of Mars, and Martial, used as an adjective corresponding to Terrestrial for Earth.

This is in contrast to the so-called superior planets, such as Mars, which appear to move independently of the Sun. infrared astronomy
The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...
The outer planets Jupiter, Saturn, Uranus and Neptune, compared to the inner planets Earth, Venus, Mars, and Mercury at the bottom right The four outer planets, called giant planets or Jovian planets, collectively make up 99% of the mass orbiting the Sun. [ h ] All four giant planets have multiple moons and a ring system, although only Saturn's ...
The following outline is provided as an overview of and topical guide to Mars: Mars – fourth planet from the Sun and the second-smallest planet in the Solar System , after Mercury . Named after the Roman god of war , it is often referred to as the " Red Planet " [ 1 ] [ 2 ] because the iron oxide prevalent on its surface gives it a reddish ...
