2. Since you read the jupiter chapter…
What is differential rotation?
What is unique about Io?
What differs belts from zones?
Who discovered the Great Red Spot?
What are the brown ovals in the clouds?

Jupiter Notes
Named for the Roman king of the gods
AKA: Zeus
Largest planet in our solar system
When viewed from Earth, Jupiter appears
brighter than most stars
Magnitude: -2.94

5. By the numbers
5.2 AU from the sun Revolves almost every 12 Earth years 3 degree tilt Rotation rate: about 10 hours Density: g/cm3 (Because of Jupiter's low density, astronomers believe that the planet consists primarily of hydrogen and helium, the lightest elements.) Force of gravity: m/s2 Eccentricity: .048 Diameter: 88,846 miles

6. Moons
four largest moons discovered by Galileo Galilei in 1610
( Io, Europa, Ganymede, Callisto)
Jupiter has 67 moons

7. Jupiter is a giant ball of gas and liquid
Features
Jupiter is a giant ball of gas and liquid
The planet's surface and is composed of dense red, brown, yellow, and white clouds. The clouds are arranged in light colored areas called zones and darker regions called belts that circle the planet parallel to the equator.
The atmosphere of Jupiter is composed of about 86 percent hydrogen, 14 percent helium, and tiny amounts of methane, ammonia, phosphine, water, acetylene, ethane, germanium, and carbon monoxide.

8. Great red spot
Observed by Robert Hooke Jupiter's most outstanding surface feature is the Great Red Spot, a swirling mass of gas resembling a hurricane. The widest diameter of the spot is about three times that of Earth. The color of the spot usually varies from brick-red to slightly brown. Rarely, the spot fades entirely. Its color may be due to small amounts of sulfur and phosphorus in the ammonia crystals. The edge of the Great Red Spot circulates at a speed of about 225 miles (360 kilometers) per hour. The spot remains at the same distance from the equator but drifts slowly east and west. The zones, belts, and the Great Red Spot are much more stable than similar circulation systems on Earth. Since astronomers began to use telescopes to observe these features in the late 1600's, the features have changed size and brightness but have kept the same patterns.

9. Rings
Jupiter has 4 faint rings mostly composed of dust Not visible from Earth Outer rings are faint and are called the Gossamer Rings; inner ring is thick and called the halo

10. Pioneer 10 was the first spacecraft to fly past Jupiter (1972)
Missions
Pioneer 10 was the first spacecraft to fly past Jupiter (1972)
Discovered that Jupiter has an enormous magnetosphere.
Galileo monitored Jupiter's atmosphere and observed the planet's major satellites (1989)
Galileo's observations of Europa had shown that it might have an ocean below its surface capable of supporting life.
Juno: launched in 2011 and arrived in July of 2016
Goal is to reveal the story of the formation and evolution of Jupiter.

11. Explain the theory that accounts for Jupiter’s internal heat source.
Text pg 265
Work with a partner to answer the following questions only 1 paper will be turned in:
Describe how Voyager and Galileo missions changed our perception of Jupiter.
Explain the theory that accounts for Jupiter’s internal heat source.
What is Jupiter thought to be like beneath its clouds? Why do we think this?
What evidence do we have for liquid water below Europa’s surface?
Why is there speculation that Europa might be an abode for life? What might be the consequences of the discovery of life on Europa?
