Solar System
Sun
• The sun is a star
• Ball of hot burning gasses
• Makes up 99.8% of the entire mass of the solar system
• Made up of:
• 75% Hydrogen
• 25% helium
• Temperature at the core is 15 million degrees Celsius
Sun
Planets
• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus,
Neptune
• Mnemonic: My Very Educated Mother Just Served Us
Noodles
Mercury
• Closest Planet to the sun
• Smallest planet in the solar system
• Daytime temperatures can reach 450 degrees Celsius
and then drop to -170 degrees Celsius at night.
Mercury
Venus
• 108 Million Km (67 million miles) from Sun
• The hottest planet in our solar system.
• Has clouds of toxic gas.
• Temperatures of 460 degrees Celsius.
Venus
Earth
• 150 million Km (93 million miles)
• Made up of:
• 78% Nitrogen, 21% oxygen, 1% other
• 70% of the Earth’s surface is covered in Oceans
• Rocky planet/terrestrial planet
Earth
Mars
• 228 million Km (142 million miles) from sun
• Rocky Planet/Terrestrial Planet
• Altered Surface:
• Volcanoes
• Impacts
• Crustal movements
• Atmospheric effects (ex. Dust storms)
• Atmosphere made up of mostly Carbon dioxide, nitrogen,
argon
• Known as the Red Planet
Mars
Jupiter
• 778 million Km (484 million miles) from sun
• Atmosphere:
• Made up of Hydrogen and Helium
• A gas planet
• Has the most mass but low density
• Separated by asteroid belt
• Jupiter has a great red spot that is a gigantic storm(bigger
than earth) that has been raging for hundreds of years.
Jupiter
Saturn
• 1.4 billion Km (886 million miles) from sun
• Atmosphere:
• Made up of :
• Hydrogen and Helium
• Gas-giant planet
• Has 7 rings
Saturn
Uranus
• Called a gas giant or Ice giant
• Very low density
• Made up largely of gas
• A decent percent of those gasses are trapped as ice.
• Gets its blue color from Methane gas.
Uranus
Neptune
• Also an ice giant
• Has many of the same frozen gasses as Uranus
• Gets its bluish color from Methane gas
Neptun
