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.
Earth and Moon, imaged by Mars Global Surveyor from its orbit around Mars on May 8, 2003, 13:00 UTC. South America is visible. [25] [26] 2014 Curiosity 's first view of the Earth and the Moon from the surface of Mars (January 31, 2014). [27] 2016 Earth and the Moon as viewed from orbit around Mars (MRO; HiRISE; November 20, 2016) [28]
It is designated α Ursae Minoris (Latinized to Alpha Ursae Minoris) and is commonly called the North Star or Pole Star. With an apparent magnitude that fluctuates around 1.98, [ 3 ] it is the brightest star in the constellation and is readily visible to the naked eye at night. [ 16 ]
On Earth, a pole star would lie directly overhead when viewed from the North or the South Pole. Currently, Earth's pole stars are Polaris (Alpha Ursae Minoris), a bright magnitude 2 star aligned approximately with its northern axis that serves as a pre-eminent star in celestial navigation , and a much dimmer magnitude 5.5 star on its southern ...
Planum Boreum (Latin: "the northern plain") is the northern polar plain on Mars.It extends northward from roughly 80°N and is centered at Surrounding the high polar plain is a flat and featureless lowland plain called Vastitas Borealis which extends for approximately 1500 kilometers southwards, dominating the northern hemisphere.
Many martian dunes strongly resemble terrestrial dunes but images acquired by the High-Resolution Imaging Science Experiment on the Mars Reconnaissance Orbiter have shown that martian dunes in the north polar region are subject to modification via grainflow triggered by seasonal CO 2 sublimation, a process not seen on Earth.

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.
Vastitas Borealis is often simply referred to as the northern plains, northern lowlands or the North polar erg [3] of Mars. The plains lie 4–5 km below the mean radius of the planet, and is centered at 87°44′N 32°32′E / 87.73°N 32.53°E / 87.73; 32.
