My planet is named Jupiter after the Roman god of the skies and lightning, who is also the Greek equivalent of Zeus. Jupiter is the fifth planet from the Sun and is 779 million kilometers away from it. The lengths of a day on my planet is 10 hours and a year is 12 Earth years long. It is also the biggest planet in the Solar System, which fits the fact that it is named after the king of the gods. The gravity is 2.5 times stronger on Jupiter than our gravity, so a 100 pound object on Earth would weigh around 250 pounds on Jupiter. The atmosphere on Jupiter is composed of 90% hydrogen molecules and 10% helium molecules. The atmosphere is the thickest in the Solar System considering it's possible that it's atmosphere all the way down to the core. Jupiter's temperature is surprisingly hot inside the planet, reaching 145 degrees C, but it's very cold at the cloud tops, down as low as -153 degrees C. The mass of this giant planet is made up of 75% hydrogen. Jupiter's appearance is beige with tan stripes all over the planet, going from thick to thin, with a giant reddish coloured spot referred to as the "Great Red Spot" which is a 400 year old storm, but it's getting slightly smaller. There are over 63 moons orbiting Jupiter so I will just name the 4 biggest moons. They were discovered in 1610 by Galileo Galilei and were named Io, Europa, Ganymede, and Callisto. Since they were discovered by Galileo, they were called the Galilean moons. Jupiter also has rings, the main ring is 20 miles thick and 4000 miles wide, and the inner ring is called the halo 12,000 miles thick. Finally, if a human being was to be on this planet, they would instantaneously be tossed around by the wind, be freezing to death (near top)/be extremely hot (closer to core), being torn apart, while being extremely heavy, and once you're dead, you'd be electrocuted when already dead and suffocated for a extremely long time.
Everything in the universe is made up of atoms, just like us! A light year is 9.5 trillion years away, and light can travel up to 300,000 km/second, plus, light stay even after a star has died (It used up all of it's gases so it's burned out). Speaking of stars, a circle of light in the night sky is actually multiple star's light clumped together, and the distance around the Sun or our Earth is called the circumference. Then, in 12,000 years, Polaris, our "North Star", will actually no longer be the North Star, Vega will. Another cool fact is that around 10 tons of meteors hit the ground each day, but most are only as big as a grain of sand (Lotta grains).
