Mercury
• Mercury is the closest to the sun and the eighth largest planet.
• Mercury is in many ways is similar to the moon.
• its surface is heavily cratered and very old
• But mercury is more dense than the moon
• Its iron core is larger then earth
Space crafts
• Mercury has been now visited by two space crafts Mariner 10 and the Messenger
• The Messenger was launched by NASA in 2004 and will orbit Mercury starting in 2011 after several flybyes
• Mariner 10 flew by 3 times in 1974 and 1975
• Only 45% of the surface was mapped

Atmosphere
• Mercury actually has a very thin atmosphere consisting of atoms blasted off its surface by the solar wind
• Because Mercury is so hot, its atoms quickly escape into space.
• in contrast to the Earth and Venus whose atmospheres are very stable
• Mercury's atmosphere is constantly being replenished.
Magnetic Field, Satellites, visibility, Craters
• Mercury has a small magnetic field whose strength is about 1 percent of earths
• Mercury has no known satellites
• Is often visible with binoculars or even the naked eye but it is always very near the sun in difficult to see in the twilight sky.
• Some craters maybe ancient volcanic activity

Time on Mercury
• On day on Mercury is like 58.65 Earth days
• One year on Mercury is like 87.97 days on Earth
Size related to earth
• Mercury is on 1/5 the size of Earth
Who discovered Mercury
• People later discovered that the planet Mercury was discovered by Johann Hieronymus Schroeter
• he lived from 1745 to 1816.
• He did sketches on the planet Mercury and they weren't very accurate
More Useful Facts
• Mercury is the fastest moving planet in our solar system. • The length across Mercury is 4,878km. • Mercury is a bit bigger than the Earth's. • The gravity on Mercury is 38% of the gravity on the
Earth. • If you were on the surface of Mercury the sun would be
three times bigger than on the Earth. • Mercury is the second smallest planet in our solar
system. • Did you know that Titan Saturn's moon is bigger than
Mercury? Titan is also bigger than Pluto.
Weather
• Due to the small atmosphere Mercury really has no weather other than wild fluctuations in temperature.
• in fact, Mercury has the largest diurnal temperature spread of any planet in our solar system.
• This is explained by a few factors. • Mercury rotates on its axis every 59 days
relative to fixed stars such as our Sun.
Temperature
• Due to being so close to the sun mercury Is the hottest planet
