What is the composition of Jupiter?
What Is Jupiter Like? Jupiter is called a gas giant planet. Its atmosphere is made up of mostly hydrogen gas and helium gas, like the sun. The planet is covered in thick red, brown, yellow and white clouds.
How many spacecraft’s have visited Jupiter?
Nine spacecraft
Nine spacecraft have visited Jupiter since 1973, and they’ve discovered a lot about the planet. Flip through the slideshow below to find out about these spacecraft and what they’ve discovered.
What is the most extraordinary feature on Jupiter?
The most extraordinary feature on Jupiter is the Great Red Spot, a giant hurricane-like storm. Information we have already learned here: Jupiter is the fifth planet from the sun and by far the largest. Jupiter is the fourth brightest object in the Solar System.
Are there Jupiter sized exoplanets?
Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). One of the best-known hot Jupiters is 51 Pegasi b. Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star.
Is Jupiter toxic?
The gases include nitrogen, hydrogen, helium, methane, and ammonia. Not all of these gases are poisonous. Most of Earth’s atmosphere is nitrogen, and there is a little helium too. There is no oxygen on Jupiter like there is on Earth.
Has any satellite visited Jupiter?
The first spacecraft to visit Jupiter was Pioneer 10 in 1973, followed a year later by Pioneer 11. The Galileo spacecraft was the first to have entered orbit around Jupiter, arriving in 1995 and studying the planet until 2003.
What are 4 characteristics of Jupiter?

- Chemical Composition. Like other gaseous planets, Jupiter lacks a solid, rocky surface.
- Jupiter’s Rings.
- Great Red Spot.

Is Jupiter a super-Earth?
The solar system is more and more like a space oddity — Jupiter-like planets are more common around stars that also host giant-size versions of our planet, while our solar system possesses Jupiter but no such “super-Earth,” a new study finds.
What planet is bigger Jupiter?
Take Jupiter and Saturn, they both have a diameter nine times more than Earth. Well, now a new planet, called OGLE-2016-BLG-1190Lb, has been discovered by Nasa’s Spitzer Space Telescope – and it’s 13 times bigger than Jupiter.
Is Jupiter a failed brown dwarf?
After the star has nearly reached its final mass, by accreting gas from the disk, the leftover matter in the disk is free to form planets. “Jupiter is generally believed to have formed in a two-step process. Brown dwarfs lack sufficient mass to shine, so they might more fairly be described as “failed stars.”
Quelle est la rotation de la planète Jupiter?
Rotation de la planète Jupiter. L’inclinaison de l’axe de rotation de Jupiter est faible, seulement 3,13° c’est pourquoi il n’y a que très peu d’effets saisonniers constatés. Jupiter a une rotation très rapide, la plus rapide de toutes les planètes du système solaire.
Quel est le symbole astronomique de Jupiter?
Le jour « jeudi » fait référence à Jupiter, le « jour de Jupiter ». Le symbole astronomique de Jupiter est ♃. L’inclinaison de l’axe de rotation de Jupiter est faible, seulement 3,13° c’est pourquoi il n’y a que très peu d’effets saisonniers constatés.
Comment sont les nuages à l’intérieur de Jupiter?
Les nuages à l’intérieur sont en rotation sur une période de 6 jours et la vitesse des vents atteint les 400 km/h sur la partie extérieure. On peut voir des formations du même genre dans l’atmosphère de Jupiter mais aussi dans celle de Saturne et de Neptune, mais Jupiter est la planète qui en possède le plus.
Quelle est l’atmosphère de Jupiter?
Jupiter possède une atmosphère très dynamique et colorée. On distingue notamment, même depuis la Terre, plusieurs bandes nuageuses couleurs différentes et un anticyclone gigantesque, la « Grande tâche rouge » qui pourrait contenir 3 fois la Terre. Les vents dans la partie supérieure de l’atmosphère atteignent les 600 km/h.
