How dense is jupiter?

67 are known, although some are just big rocks. The ones you see in a telscope are the Galilean moons, Callisto, Europa, Ganymede and Io.

483.8 million miles on average. (Jupiter like most planets has an elliptical as opposed to circular orbit.)

Since the Earth and Jupiter are both revolving around the sun, the distance between them is always changing. The average distance between the Earth and Jupiter is 483 million miles. If you could travel at the speed of light, it would only take you 43 minutes to get to Jupiter. Since people cant travel at the speed of light, you would probably have to take a rocket ship to Jupiter instead- which would take you about 2.2 years if it was going at top speed the whole way. If the California interstate went all the way to Jupiter and you could drive there going 65 mph, it would take you almost 850 years!

Jupiter's density is about 1.33 grams per cubic centimeter.

All four of the inner (terrestrial) planets have higher densities than the four outer (gas giant) planets. See Density of the Planets

Thanks heavens for NASA. They've got lots of information about Jupiter including Facts and Figures.

The biggest planet in our solar system is Jupiter. Jupiter is the fifth planet from the sun and the largest in the solar system.

Astronomers say they have discovered what appears to be an entirely new kind of planet, an extra-large gas giant unlike any known world in our solar system or beyond. The planet, dubbed HAT-P-1, is located some 450 light-years from Earth in the constellation Lacerta.
It is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's.
HAT-P-1 is also the least dense of all known planets.
