Many astronomical phenomena viewed from the planet Mars are the same as or similar to those seen from Earth; but some (e.g. the view of Earth as an evening/morning star) are quite different. For example, because the atmosphere of Mars does not contain an ozone layer , it is also possible to make UV observations from the surface of Mars.
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.

Mars is a terrestrial planet with a thin atmosphere , having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth .
The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
Olympia Undae is the largest field of sand dunes on the planet Mars. Olympia Undae is a vast dune field in the north polar region of the planet Mars . It consists of a broad "sand sea" or erg that partly rings the north polar plateau ( Planum Boreum ) from about 120° to 240°E longitude and 78° to 83°N latitude.
