2. The general facts
Revolve: To revolve is to complete an orbit around an object
Rotate: To rotate is to circle around your center
Orbit: To travel in a curved path around an object
Currently there are now 8 planets in the solar
The inner planets include Mercury, Venus, Earth and Mars
The outer planets include Jupiter, Saturn, Uranus, and Neptune
The inner planets are mainly made up of rock and dirt, while the outer planets are made up of gas balls
In the first 600 million years which inner planets existed, they were constantly being hit by meteoroids
To be a planet,an object must have a round shape due to its gravity, orbit around the sun, andits orbit path must not have stuffs that are about its own size floating around
A dwarf planet is a planet that meets the first 2 requirements but not the third one
Three dwarf planets are Pluto, Eris, and Ceres
3. Mercury
Mercury's atmosphere is caused by the heating of the sun - the sun heated mercury so much that its atmosphere is very thin.
Mercury's atmosphere is consisted of sodium and helium.
Objects strikingthe surface of mercury making craters, lava on the surface because of volcanoes, and the crust of mercury
moving so that mercury can adjust to the contraction it has shaped mercury.
4. Venus
Venus is called the evening star because when you look from earth it is considered the brightest planet that could be seen.
The clouds in Venus reflects the sun's light.
You can find carbon dioxide and sulfuric acid in Venus.
Retrograde rotation is rotation in which that the planet rotates in a clockwise direction unlike other planets.
A Venus day lasts longer than a Venus year because its rotation is slower than its revolution! Rotating takes 243 Earth days, and
a revolution takes 225 Earth days.
The sun seems to rise in the west and set in the east because it rotates clockwise unlike the other planets so the sun comes out
in the west.
Venus is the hottest planet in your solar system because its atmosphere acts like a green house which traps the heat that is
from the sun.
Cautious: Hot!
5. Earth
Earth's atmosphere consists of 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% of other gases.
Earths atmosphere protects us from solar radiation and meteors who are trying to crash into Earth at anytime.
The rotational tilt of Earth is 23.5 degrees.
The rapid spin of Earth with a hot core produces Earths magnetic field.
The satellite of Earth is the Moon.
6. Mars
Pieces of meteorites found in Earth from Mars had traces of bacteria, so life may have existed in Mars in the past.
The atmosphere of Mars is mostly made of carbon dioxide.
Mars appears to be red because of its iron in Mars soil.
Olympus Mons is the largest volcano in Mars.
Phobos and Deimos are the two satellites on Mars.
7. Jupiter
Jupiter had such a rapid rotation that its equator bulged and its poles were flattened.
Sulfur, helium, nitrogen, and hydrogen are believed to be components of Jupiters atmosphere.
A huge storm that looks like a hurricane in Jupiter is the Giant Red Spot.
Jupiter had 63 natural satellites.
One of Jupiters satellites called Io has active volcanoes on it.
8. Saturn
Hydrogen and helium makes up Saturns atmosphere.
The leftovers of meteoroids which crashed into Saturn caused Saturn to have rings.
Ice and dust make up Saturns rings.
Saturns low density makes it float in water.
Seasons on Saturn lasts more than 7 Earth years.
9. Uranus
Uranus is tilted 98 degrees, therefore it looks like that it is rotating on the sides unlike other planets.
Hydrogen, helium and methane makes up Uranus's atmosphere.
It is known that Uranus has 27 satellites revolving around it.
10. Neptune
Neptunes atmosphere contains helium, methane, and ammonia.
Neptune has 13 known satellites.
Triton is the largest satellite of Neptune. Astronomers guessed that Triton was being forced into Neptunes gravity, so it became an orbiting satellite like that.
11. Pluto
Plutos three moons are Nix, Hydra, and Charon.
Scientists have detected frozen methane on Pluto and frozen water on Charon.
Charon is a bit bluer than Pluto, and it snows frosts when Pluto is farthest from the sun.
12. Ceres
Ceres revolution around the sun once takes about 4.6 Earth years.
It was considered as an asteroid in the past because it is located in the middle of the asteroid belt.
You can find water, ice, carbonates and clay on Ceres.
13. Eris
Eriss original name was Xena, a popular TV show at the time when it was founded.
If Eris orbited the sun once, 557 Earth years would pass.
Eriss moon is called Dysnomia.
Eris isnt considered to be a planet because it has random unidentified stuffs around its orbit path that it hasnt cleared yet
