Facts & Summary
Jupiter is the fifth planet from the Sun and the biggest planet of our Solar System. Some consider it a failed star since it is made out of swirling gases and liquids such as 90% hydrogen, and 10% helium – very similar to the Sun.
Jupiter is the fourth brightest object in the sky and one of the five visible planets ( Mercury, Venus, Mars, Saturn ).
The envelope of gases – atmosphere – surrounding Jupiter is the largest planetary atmosphere in the Solar System. It makes up almost the entire planet. Basically, it doesn’t have a true surface with its atmosphere reaching altitudes of 5.000 km / 1.864 mi.
Through the observations of Jupiter, the discovery of the four Galilean moons ended the belief that everything revolved around the Earth.
Jupiter has a total of 79 confirmed moons. It is second only to Saturn when it comes to the total amount of satellites.
Jupiter also has 3 ring systems but much smaller than Saturn’s.
Though they can be seen only through ultraviolet, Jupiter’s auroras are the brightest in the Solar System.
Jupiter has a mean radius of 69.911 kilometers / 43.440 miles, a diameter at the equator of around 142.984 km / 88.846 mi, and a diameter at the poles of 133.708 km / 83.082 mi.
Jupiter’s mass is almost twice of all the Solar System’s planets combined. It is 318 times more massive than Earth.
Jupiter is on average about 5.2 AU away from the Sun. One AU is equivalent to 150 million km / 93 million mi.
Jupiter experiences 200 times more asteroid and comet impacts than Earth.
In a way, Jupiter is the Solar System’s vacuum cleaner, because of its powerful gravity which attracts many of the comets and asteroids to hit it rather than other planets.
