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 ...
[ VIDEO] NASA’s Ingenuity Mars Helicopter hovers over the Martian surface – the first instance of powered, controlled flight on another planet – as viewed by the Mastcam-Z imager aboard the Perseverance Mars rover on April 19, 2021. The helicopter climbed to an altitude of 10 feet (3 meters), hovering for 30 seconds.
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.
Comet Swift–Tuttle (source of the Perseids) comes to perihelion. [44] 2126 July 29 At 16:08 UTC, Mercury will occult Mars. [31] [42] [45] 2130 March 10 At 07:32 UTC, Sun passes through the Solar System barycenter. [46] 2133 December 3 At 14:10 UTC, Mercury will occult Venus. [31] [42] 2134 March 27 Halley's Comet will be at perihelion during ...
2016 CP 31 is a small asteroid and Mars trojan orbiting near the L 5 point of Mars (60 degrees behind Mars on its orbit). [ 2 ] [ 3 ] [ 4 ] Discovery, orbit and physical properties
As on Earth, there is a second form of precession: the point of perihelion in Mars's orbit changes slowly, causing the anomalistic year to differ from the sidereal year. However, on Mars, this cycle is 43,000 Martian years (81,000 Earth years) rather than 112,000 years as on Earth.
The ancient Greek astronomer Hipparchus noted the apsidal precession of the Moon's orbit (as the revolution of the Moon's apogee with a period of approximately 8.85 years); [4] it is corrected for in the Antikythera Mechanism (circa 80 BCE) (with the supposed value of 8.88 years per full cycle, correct to within 0.34% of current measurements).

A high resolution topographic map of Mars based on the Mars Global Surveyor laser altimeter research led by Maria Zuber and David Smith. North is at the top. North is at the top. Notable features include the Tharsis volcanoes in the west (including Olympus Mons ), Valles Marineris to the east of Tharsis, and Hellas basin in the southern hemisphere.
