Jupiter is my favourite planet. Also known as the Wandering Star, Jupiter is the largest planet in the solar system. It has at least 67 moons, of which the largest four (Io, Ganymede, Europa, and Callisto) were discovered by Galileo in 1609 and 1610. Jupiter is a gas planet.
The most well-known feature of Jupiter is the Great Red Spot, a storm bigger than the size of Earth, swirling violently through Jupiter's atmosphere. Jupiter also has rings, which are made up of dust and little rocks.
At least two spacecrafts have been deliberately crashed into the surface of Jupiter to take readings inside the atmosphere.
In addition, Jupiter has an aurora.
In conclusion, Jupiter is awesome.
