Jupiter is the 5th closest planet to the Sun, and is also the largest planet. It is such big that many earth can fit inside of it
Jupiter's atmospheric composition is made of the same elements as the Sun, hydrogen and helium. However, unlike the Sun, Jupiter does not have enough gravity to begin nuclear fusion and become a star. But Jupiter is at the very edge of becoming a Brown Dwarf Star, as it is denser that the largest exoplanet in the Milky Way.
Season on Jupiter are not very extreme because of his tilt. It takes nearly 12 years to complete his orbit but here the interesting is that t is the fastest rotational planet in the solar system because it takes only 10 hours to complete one rotation.
Like all the other Jovian planets, Jupiter has a ring system. However, its ring system is the least massive out of all the planets and is much smaller than Saturn's extensive ring system and is barely visible.

Impact by Shoemaker-Levy 9[]
Main Link: Comet Shoemaker-Levy 9
Shoemaker Levy-9
D/1993 F2, or Comet Shoemaker-Levy 9, is a short-period comet that began orbiting Jupiter around the early 1980's. On July 16, 1994, the first comet impacted on 8:13 pm. Before this, the comet split into 21 pieces, and the first one to hit was designated as "fragment A". The other ones collided at different times after the fact. To the right is the picture of the comet once it split into its fragments before it collided into Jupiter.
Flyby Missions[]
The flyby missions of Jupiter began in the year of 1973 with, the most notable spacecraft, Pioneer 10, making its first flyby in December of 1973. The last flyby mission was made by New Horizons, which came within two million miles of Jupiter. The farthest approach was made by the second Ulysses mission, which came within one hundred twenty million miles of the planet. The closest approach of of them all was Pioneer 11, which came with thirty thousand kilometers of the planet.
Below is a chart of the spacecrafts, their closest approaches, in kilometers, and the date of their closest approaches.

| Pioneer 10 | 129,560 kilometers | December 3, 1973 |
| Pioneer 11 | 33,700 kilometers | December 4, 1974 |
| Voyager 1 | 348,950 kilometers | March 5, 1979 |
| Voyager 2 | 595,000 kilometers | July 9, 1979 |
| Ulysses (1st mission) | 410,000 kilometers | February 8, 1992 |
