History• Mercury as named

after the Roman god Mercury

• It is the closest plant to the Sun

• Known about since ancient times

• Greeks called it Apollo as the morning star and Hermes as the Evening star

Mercury

god of trade

Rotation• Mercury rotates

around the sun every 88 days

• Second slowest planet to rotate around the sun (Venus being the slowest)

• One day on Mercury lasts 176 earth days

Page 4: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Revolution• 58.6 Earth days

Page 5: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Distances• Closest Planet to Sun• Average distance from Sun: 57,910,000 km (36

million miles)

Page 6: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Distances• Opposition (closest distance from Earth, but

farthest from Sun): 77 million km (48 million miles)

• Farthest distance (opposite sides of Sun): 222 million km (138 million miles)

Size• Surface Area: 7.48 x 107 km2 - 10.8% of Earth’s

surface area• Volume: 6.083 x 1010 km2 - 5.4% of Earth’s

volume.• Equatorial Diameter: 4,879 km (15,988,845 feet)

Page 8: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Size• Second smallest planet• Some scientists believe it is shrinking due to its

liquid core and rotation• The rotation is cooling parts of the core• Terrestrial Planet

Page 9: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Density• Second most dense• Density: 5.427 g/cm3 (Earth: 5.515 g/cm3)• If gravitational compression was not taken into

account, Mercury would be more dense• Most density comes from core (42% of volume)

Page 10: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Temperature• Has a huge range in temperature• Ranges from -168oC – 428oC (-270oF – 800oF)• Daytime: temperatures rise very high (only Venus

is hotter)

• Nighttime: thin atmosphere releases temperatures so it drops quickly

Composition

• Mercury isn’t very dense so it doesn’t have than much gravity

• It has a large core which is most likely partly molten and generates a magnetic field about 1% as strong as Earth’s

• Interior resembles that of Earth• Has a rocky layer, called the mantle, beneath the

crust and an iron core

Atmosphere• Planet is too small to hold down a normal

atmosphere and the one it has is constantly being blown away; however, there is a very thin one

• Atmosphere consists of: hydrogen, helium, oxygen, sodium, potassium, calcium, and magnesium

• Atmospheric pressure at surface is 1 trillionth of Earth’s

Satellites

• There are no satellites orbiting Mercury

Page 14: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Physical Characteristics

• The smallest planet• Brown• Dry

Page 15: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

Physical Characteristics• Rocky & crater-like• Looks like the moon• Has some plains & hills

What it Would Be Like to Go There

• Its impossible!• No water or living life

Page 17: Mercury By Megan Carlson, Kaya Hall, Jacob McHugh, & Lilli McCreery

What it Would Be Like to Go There

• Severe weather change• Very icy• Burning hot• Lava eruptions on surface
