Our solar system has 8 planets and a dwarf planet, so we have 9 planets in all. Our sun is in the middle of the solar system. By Courtney Sindoni
The sun is the largest object in our solar system. The sun will eventually blow up in 500 billion years. The sun is bigger than all the planets put together.
Mercury is the closest planet to the sun. Mercury is also as big as Earth’s moon. Mercury have no moons.
Venus is the second closest planet to the sun. Venus is also the same size as Earth. Venus has no moons.
Earth is the only planet that has life and water. It is the third planet from the sun. Earth also rotates on its axis. It takes Earth 24 hours for a day and 365 ¼ for a year. Earth has one moon and it is called Luna.
Mars has a robot on it and it is very cold. Mars is the 4 th planet from the sun. Mars’s nickname is the “The Red Planet,” Mars has three known moons, and two of them are called Deimos and Phobos.
The asteroid belt runs between Mars and Jupiter. The asteroid belt is made of metal, and rock.
Jupiter is the fifth planet from the sun. It is by far the biggest planet. Jupiter has at least 62 moons that are very small.
Saturn is the sixth planet from the sun. Saturn has no known solid surfaces. Saturn has at least 62 moons currently.
Uranus is the seventh planet from the sun. Uranus rolls on it’s side and rotates around the sun. Uranus has 27 moons.
Neptune is the eighth planet from the sun. Neptune is one of the windiest places in the solar system. Neptune has 13 known moons.
Pluto is a dwarf planet. It is the ninth planet from the sun. Pluto has 2 moons.
Comets are a ball of rock, ice, and frozen gases. A comet’s orbit brings it close to the sun.
The moon orbits around Earth. It has many craters on it from asteroid that land on it.
Constellations are a group of stars that make a picture in the sky. The Big Dipper, The Little Dipper, and The Orion are constellations.
Black Holes have 3 main parts. The outside is called the Outer event Horizon. The middle is called the Inner Event Horizon. The center is called the Singularity.
The universe is made of dust, gas, clouds, galaxies, and stars. The universe is very big.
The galaxy we live in is called “The Milky Way.” “The Milky Way” is the most significant galaxy to humans because it is our home sweet home.
An asteroid is a large piece of rock in space. Some asteroids can be as small as a grain of sand. Asteroids called Ceres are very large.
Stars fill most of the sky at night. They are bright, and if they are big enough they will shine up the hole sky so you can see at night. A couple of stars have been found 100 or 200 times larger than the sun.
A meteorite is a steak of light in the sky. Some people call them “shooting stars,” or “a falling star.”
Every planet has an axis. An axis is an imaginary line through the center of all planets. All planets rotate on their axis.
The Milky Way is the galaxy that we live in. The Milky Way holds all of the planets and stars that are in our solar system.
Gravity is what holds us on the ground. If we had no gravity we would be floating in mid- air.
Our atmosphere is all around Earth. It is right by the crust of the Earth.
Craters are big holes in the ground. The big holes are formed by asteroids that come down on Earth, that is why they are called “Craters.”
Gaseous is a type of planet. The gaseous planets are the outer planets. They are Jupiter, Saturn, Uranus, and Neptune. Jupiter Saturn Uranus Neptune
Terrestrial is a type of planet. Earth is a terrestrial planet. The terrestrial planets are the inner planets. They are Mercury, Venus, Earth, Mars, and Pluto. Mercury Venus Earth Mars
A galaxy is made of gases, dust, and stars. Earth is 75% water, so that means 25% of Earth is not water. The galaxy we live in is called The Milky Way. Our galaxy has inner planets and outer planets. Our universe is everything that exists in space. There is 4 inner planets and 4 outer planets. Arthromeres say that they have found other stars that are 100 or 200 times larger than the sun, but they are not in our galaxy. All the planets have days and years with all different times as the other planets.
THANKS FOR WATCHING!!!!!! I HOPE YOU ENJOYED IT ON OUR SOLAR SYSTEM!!!!
