For purposes of enumerating Mars years and facilitating data comparisons, a system increasingly used in the scientific literature, particularly studies of Martian climate, enumerates years relative to the northern spring equinox (L s 0) that occurred on April 11, 1955, labeling that date the start of Mars Year 1 (MY1).
Badwater Crater is an impact crater located in Hellas Planitia and is situated within the low lying Plain of Peneus Palus on the southern hemisphere of Mars.It contains the lowest currently [as of?] known point on the entire planet, with an elevation of approximately −8,200 metres (−26,900 ft) [2] at 32.79° S, 62.14° E. [1] Badwater has a diameter of approximately 33.14 kilometres (20.59 ...
The Clancy Mars year is reckoned from one Martian northward equinox to the next (L s = 0°), and specific dates within a given year are expressed in L s. The Clancy Mars year count is approximately equal to the Darian year count minus 183. The Allison Mars sol date epoch equates to L s = 276.6° in a year that is undefined in the Clancy Mars ...
Mars Year 1 is the first year of Martian timekeeping standard developed by Clancy et al. [1] originally for the purposes of working with the cyclical temporal variations of meteorological phenomena of Mars, but later used for general timekeeping on Mars. Mars Years have no officially adopted month systems.
Mars, in particular, turns retrograde approximately every two years (or 26 months) for around three months. However, due to its pre- and post-shadows, the complete duration of a Mars retrograde ...
At one point, 1.35 million Earth years ago, Mars had an eccentricity of roughly 0.002, much less than that of Earth today. [188] Mars's cycle of eccentricity is 96,000 Earth years compared to Earth's cycle of 100,000 years. [189] Mars has its closest approach to Earth in a synodic period of 779.94 days.

Mars is the celestial body in the solar system with the most similarities to Earth. A Mars sol lasts almost the same as an Earth day, and its axial tilt gives it similar seasons. There is water on Mars, most of it frozen at the Martian polar ice caps, and some of it underground. However, there are many obstacles to its habitability.
