Mercurys Orbit

• Mercury is the closest planet to the sun and has
  a very unusual orbit. The path that mercury
  follows around the sun is called at ellipse.
• At its closet point, Mercury is only 27 million
  miles away at its closet, it is 41 million miles
  away.

Mercury Compared To Earth!

• One of Mercurys days, is 2/3 as long as one of
  its years. There are 88 earth days in a Mercurian
  year. It takes Mercury 59 earth days to complete
  a trip around the sun.
• The gravity on Mercury is only about 38 of the
  gravity on earth. A person that weights a 100
  pounds on earth would only weigh 38 pounds on
  Mercury.

Mercurys Atmosphere

• Mercurys atmosphere is so thin its like it
  doesnt even have one. In fact, Mercurys
  atmosphere is only 1 trillionth of the size of
  earths.
• Mercurys atmosphere is most dense in the
  daytime and it is made up of 56 oxygen, 35
  sodium, 8 helium, and only 1 of potassium and
  hydrogen.

Mercurys Weather

• Though Mercury is the closest planet to the sun,
  it is not the hottest. Mercury has the greatest
  difference in temperature between day and night.
• The temperature in the day is around 806 degrees
  F. In the night time, it drops dramatically to
  -292 degrees F.
• The temperature difference between day and night
  on Mercury can be as much as 1,080 degrees!

Mercurys Physical Features

• Mercury is mostly made up of iron. It is also
  covered in many craters because it has
  practically no atmosphere.
• The surface of mercury is thought to be made up
  of igneous silicate rocks and dust.

Exploration of Mercury

• Messenger's is a scientific investigation of the
  planet Mercury. Understanding Mercury, and the
  forces that have shaped it, is fundamental to
  understanding the terrestrial planets and their
  evolution.Messenger's journey will include one
  Earth flyby, two Venus flybys and three Mercury
  flybys before it enters orbit in 2011. The flybys
  will help focus the science mission when
  Messenger's enters orbit. The spacecraft is
  expected to orbit Mercury for one year.
