Jupiter is the fifth and largest planet in our solar system. This gas
giant has a thick atmosphere, 17 moons, and a dark, barely-visible
ring. Its most prominent features are bands across its latitudes and a
great red spot, (which is a storm). Jupiter is composed mostly of gas.
This enormous planet radiates twice as much heat as it absorbs from
the sun. It also has an extremely strong magnetic field. It is
slightly flattened at its poles and it bulges out a bit at the
Jupiter's diameter is 88700 miles (142800km). This is a little more
than 11 times the diameter of the Earth. Jupiter is so large that all
the other planets in the solar system could fit inside it (if it were
Mass and Gravity:
Jupiter's mass is about 1.69 x 10(27) kg. Although this is 318 times
the mass of the Earth, the gravity on Jupiter is only 254% of the
gravity on Earth. This is because Jupiter is such a large planet (and
the gravitational force a planet exerts upon an object at the planet's
surface is proportional to its mass and to the inverse of its radius
squared). A 100-pound person would weigh 254 pounds on Jupiter.
Length Of A Day And Year On Jupiter
It takes Jupiter 9.8 Earth hours to revolve around its axis (this is a
Jovian day). It takes Jupiter 11.86 Earth years to orbit the sun once
(this is a Jovian year).
Jupiter is made of gases and liquids, so as it rotates, its parts do
not rotate at exactly the same velocity. It rotates very rapidly, and
this spinning action gives Jupiter a large equatorial bulge; it looks
like a slightly flattened sphere (it is oblate.).
Jupiter is 5.2 times farther from than the Sun than the Earth. On
average, it is 480,000,000 miles (778,330,000 km) from the sun.
Jupiter is 749,900,000 Km from the Sun. Jupiter has no seasons.
Seasons are caused by a tilted axis, and Jupiter's axis is only tilted
3 degrees (not enough to cause seasons). Jupiter has four large moons
and 13 small ones. Galileo...
