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).
: (1) What is Gravity? Gravity is a force that cannot be seen. Gravity holds us down so we won't float off into space. Gravity is also the force that keep the planets rotating around the sun, comets/meteors land on Earth, and the force that makes the tides in oceans how it is. The rings around the gas planets, are all just small meteors and comets that came into orbit and are held in place and rotating around the planets. Another thing gravity does is keep the moons of several different planets around itself. If gravity didn't exist, the Solar System would be seperated and floating all around space. Another thing that is related to gravity is black holes. Black holes appear pitch-black because they suck in light and doesn't let it escape using gravity.
(2) Describe the position, motion, and components of our Solar System. Mercury: closest to the sun. Year: 88 days Day: 59 days Venus: 2nd closest Year: 224 days Day: 243 days Earth: 3rd closest Year:365 days Day:24 hours Mars: 4th closest Year: 687 Day: 24 hours Jupiter: 5th closest Year: 12 years Day: 10 hours Saturn: 6th closest Year: 30 years Day: 10 hours Uranus: 7th closest Year: 84 years Day: 18 hours Neptune: 8th closest Year: 163 years Day: 19 hours 3. Compare the environment of Earth's environment versus your planet. Jupiter: Jupiter's atmosphere is primarily made up of 90% hydrogen and 10% helium. Meanwhile the temperature on Jupiter in the clouds go as low as -145 degrees C. VS Earth: Whereas Earth's atmosphere is mostly made of 78% nitrogen 21% oxygen 1% argon, and the temperature on Earth dips and rises differing on where you are reaching up to -88 to 58 degrees C. 4. Describe the overall scale, structure and age of our universe Saturn is the 2nd biggest planet in the solar system. Although compared to Jupiter, it's only 1/3 the mass of Jupiter it's still 95 times bigger than Earth. Structurally, it's made up of gas, and it has 7 rings, 4 main ones, then 3 smaller, fainter ones. The age of our universe is 14 billion years. 5. Facts on Earth Our planet is the only populated planet in our solar system (excluding Mar's population of robots). Our planet is covered in 70 percent water. You would need to fit 1.4 million earths into the sun to fill it up. It was once thought that Earth was the center of the universe and the Sun and the rest of the planets revolved around it. Earth is the only planet to have not been named after a Greek or Roman deity. |
