Jupiter
Cody and Brett
Introduction
 Jupiter
is the fifth planet from the sun.
 If
it were a hollow planet, over one thousand Earths
could fit inside.
 It
is two and a half times the mass of all the other
planets combined ( 1.9 x 10^27 kg)
 142,800
km diameter.
Facts
 Jupiter
has very faint rings, and is totally invisible from
Earth. The Voyager 1 discovered it in 1979,
 Has
a very deep atmosphere, composed of mainly
Hydrogen and Helium
 Atmospheric
clouds and storms, which look like
colorful latitudinal bands, illustrate the dynamic
weather. The weather can change in hours, or days.
Jupiter’s Rings In-Depth

Much smaller and harder to see than Saturn’s (invisible to the naked eye)

Consists mostly of rocky material

They appear to have no ice, unlike Saturn
Other Characteristics

Its core’s temperature is around 20,000 K

Its magnetosphere is much stronger than Earth’s

It extends over 650 million km (that breaches the orbit of Saturn)
The Red Spot
 The
red spot is a complex storm that moves in a
counter-clockwise direction.

Astronomers believe that the spot is red because it
pulls up darker compounds from the planet.

A century ago it measured at about 40,000 km, but
today has shrunk to about half that size.
The Red Spot

It has been observed for over 300 years

Its discovery is generally attributed to Robert Hooke in the 17th century
Moons
 Jupiter
 The
has 62 known moons.
four largest are Europa, Callisto, Ganymede, and
Io.
 They
are named after Galileo who first discovered
them around 1610.
Moons

Jupiter is slowing down due to the gravitational pull by its moons

That same gravitational force is pushing the moons away from Jupiter
Life on Europa?

Probably not

But, Europa is covered by frozen water and has a surface temperature of 260ºF

It is possible there is liquid water beneath the surface, being heated from
the core
Summary

Jupiter is the 5th planet from the Sun

If it were a hollow planet, over one thousand Earths could fit inside.

Jupiter has 62 known moons.

They are not laughing at Jupiter, they are overjoyed at their discovery
