Mars, an example of a cold desert planet, seen by the Mars Orbiter Mission space probe. A desert planet, also known as a dry planet, an arid planet, or a dune planet, is a type of terrestrial planet with an arid surface consistency similar to Earth's deserts. Mars is a prominent example of a desert planet in the Solar System. [1]
The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [11]
A theoretical planet that has undergone planetary differentiation but has no metallic core. Not to be confused with the Hollow Earth concept. Desert planet: A terrestrial planet with an arid surface consistency similar to Earth's deserts. Mars: Gas dwarf: A low-mass planet composed primarily of hydrogen and helium. GJ 1214 b: Gas giant
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.

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.
