  1. Mercury Justin Moon, Jessica Kuo, Jeremy Haysman

  2. Tilt: -0.01 degrees • Rotates counter clockwise. • Length of day: 58d 15h 30m • Length of year: 88 days • Distance from sun: 35,980,000 mi • Average temperature: • Light Side: 425C • Dark Side: -173C * One side of Mercury always faces the sun so there is no daytime or nighttime. Basic Properties

  3. Basic Properties Cont. The mass of Mercury is 5.5% of Earth’s. The density of Mercury is 98.4% of Earth’s. Mercury is Terrestrial. Mercury’s mass: 70% iron, 30% silicate Atmosphere: Very thin 42% oxygen 29% sodium 22% hydrogen 6% helium 5% potassium

  4. Mercury doesn’t have any rings. • It has three layers, the crust mantle and core. • Mercury’s surface is fairly smooth with some craters and ridges. • The craters range from sizes of .1 km to 1300 km. Surface Features

  5. Discovery of Mercury Mercury has no moons that orbit it. Since Mercury is the closest planet orbiting the Sun, it was hard for astronomers to study it. The first recorded observation of Mercury was by Timocharis in 265 B.C. In the 1960’s scientists determined the correct length and day of Mercury.

  6. Exploration of Mercury Mariner 10 was the first spacecraft that went to study Mercury in 1974. Mariner 10 had three flybys around Mercury and photographed half of Mercury’s surface. Messenger was sent to Mercury to orbit and study the composition in 2004. Messenger revealed that there are volcano vents that once had hot lava.
