Lesson 5- Jupiter
Chapter 5
- Geography/Climate
- Biggest planet in our solar system
- Stronger gravity than Earth
- Exact mass is unknown
- about twice the mass of all the planets combined
- less mass than the Sun
- Rotates much faster than the other planets
- it can make a complete rotation in nine hours and fifty-five minutes
- Atmosphere
- made up mostly of hydrogen and helium
- 99%
- other gases such as methane and water vapor
- 1%
- banded- belts circling the planet
- dark belts
- low pressure regions
- light belts
- high pressure regions
- Jupiter's version of weather
- Great Red Spot
- pile of winds much like a hurricane
- discovered by Robert Hooke in the 17th century
- red color is probably due to the intensity of the winds
- Make-up of Jupiter
- core is made of a rocky material
- above core- liquid metallic hydrogen
- source of Jupiter's magnetic field
- possibly helium and ice as well
- crust is made of hydrogen and helium
- goes from liquid to gas the closer it gets to the atmosphere
- 67 moons
- most well known- discovered by Galileo in 1610- known as the Galilean moons
- Ganymede
- largest; about the size of Mercury
- half the mass of the smallest planet
- Io
- only celestial body other than Earth to have volcanoes
- atmosphere is full of sulfur dioxide snowfields
- full of fire and ice
- Callisto
- lots and lots of craters
- Europa
- barely dented with craters
- there is thought to be an ocean beneath its surface that could support life
- Rings are made of dust coming from the planet's moons
- Etymology/History
- Named after the Roman god of the sky
- 5th planet from the Sun
- About 5 to 6 AU from the Sun
- Third brightest in the night sky
- after the Moon and Venus
- Right behind the Asteroid Belt
