Transcript of Mercury.
This is the planet of the Solar System closest one the Sun, and it is also the smallest. It is part of the so-called Interior or Rocky planets and it lacks satellites. Very little is known about its surface until the Probe was sent there.
Mercury makes its appearance indirectly 13 times every century, and observers from Earth can be seen to pass mercury on the disk of the Sun, an event known as a transit. Transits will last several days. The first two transits of mercury in the 21st century occurred 07 May 2003 and November 8, 2006. The next will take place may 9, 2016.
Temperatures on the surface of mercury can reach 800 degrees Fahrenheit (427 degrees Celsius). Due to the fact that the atmosphere of mercury is so thin, the sur face can not
retain heat, so night temperatures can be down - 290 degrees Fahrenheit (- 179 degrees Celsius)..
