Jupiter

Windswept Giant

Visual Scale of Size

Visual Scale: If the sun were the

door to this room, then the earth

would be a nickel and Jupiter would

be a basketball.

If Jupiter got any more massive it

would actually start to get

smaller because it would

pull in on itself.

Stats

• 5th planet from our sun, 778 million km.

• Mass: 1.898E27 kg, Radius: 69,911 km

• Jupiter day: 10 hours, spins so fast it

bulges at the equator.

Fastest spinner in the solar system.

Jupiter year: 4,333 earth days,

= 12 earth years

Gaseous ball, predicted to have a

solid core.

Interior

• Interior: rocky core,

liquid metallic

hydrogen,

molecular hydrogen

Atmosphere

• Clouds on Jupiter are only about 50 km

thick.

• Atmosphere is H2 and He

• Storms are constant, the giant red

• spot has been raging

• for hundreds of years.

Features

• Mass: 1.898E27 kg, Radius: 69,911 km

• Strong magnetic field

• and radiation belts

Auroras

Auroras exist all

the time.

Strong solar

winds flatten

out the belts and

make the auroras

pancake shaped.

Features

• Ring: Suprise of Voyager

• 1 photograph

• Voyager 1 images gave the

• first indication of a faint ring around Jupiter. The location of the ring is indicated by the white line. The thickness of the ring is estimated to be 30 km or less. Jupiter is about 142,000 km in diameter. The ring has a diameter of about 250,000 km. North is at 11:00 (Voyager 1, P-21259)

Great Red Spot

• Actually a storm that has been visible for

at least 150 years, maybe more.

• Jupiter has no

continents

or other structures

to break it up.

Amazing Satellites

(moons)

• At least

67 known

satellites.

four are called

Voyager 1 image of Jupiter's moon Callisto from a distance of 350,000 km. The

large ‘bulls-eye’ at the top is believed to be an impact basin formed early in

Callisto's history. The bright center of the basin is about 600 km across and the

outer ring is about 2,600 km across.
