Example text

Mercury can reach 427 degrees Celsius (800 degrees Fahrenheit), and there’s a big difference between the temperature at the equator and the temperature at its poles. It has the most temperature variations of any planet in the Solar System, getting as low as -183 degrees Celsius (-297 degrees Fahrenheit). There may be deposits of minerals and ice within craters near the poles. The deepest craters are located there, and are the most likely candidates to hold ice because they always stay shadowed, never rising above -173 degrees Celsius (-279 degrees Fahrenheit).

This is probably due to perturbations, or interactions with the gravitational pulls of other planets in space. 56 degrees every 100 years. 00106 degrees every century. Some models show that increases in perturbations could cause Mercury to collide with Venus millions of years from now, but it’s a very small chance. Mercury’s chaotic, eccentric orbit is inclined from the Earth’s ecliptic plane by seven degrees. Because of this, transits of Mercury – when the planet is between the Earth and the Sun in its rotation – only occur about once every seven years on average.

Messenger’s original one-year mission ended, but NASA has extended it until March 2013. The European Space Agency and the Japanese Space Agency are planning a joint mission called BepiColombo, to put a spacecraft in Mercury’s orbit in 2015. It initially included what would have been the first lander on the planet’s surface, but that part of the mission was cancelled due to its high cost. Mariner 10 Mariner 10 departed Earth on 3 November 1973, making one flyby of Venus and three of Mercury before ceasing to transmit on 24 March 1975.
