Our solar system is over 4 billion years old. Our solar system is made up of 8 planets, five dwarf planets, and one asteroid belt. It also contains moons, comets, and meteoroids.
The Sun: The Sun is the center of Our solar system. The Sun’s gravity is what keeps the planets orbiting around It. Even though more one million Earths would fit inside the Sun
Mercury: Mercury is the closet planet to the Sun. It is cover in craters and has no moons. Mercury’s nicknames are ” morning star ” and ” evening star” because it is easiest to see Mercury right before the sunrise. Mercury turns very slowly on its axis. One day on Earth take 24 hours, One day on Mercury takes almost 59 Earth-days!
Venus: Venus is the brightest planet in our solar system and is often visible during daylight. Venus is known as Earth’s sister planet because of similarities in size and gravity. A year on Venus is equal to 224 Earth-days!
Earth: Although Earth and Venus may be like sisters, Earth is a truly unique planet in our solar system. Earth is the only planet in our solar system that supports life- at least that where we live. It’s Earth’s atmosphere that allows life to flourish on its surface. Earth’s atmosphere is a mixture of nitrogen, oxygen, and other gases.
Mars: Scientists believe that Mars may have once had lakes, rivers, and perhaps even an ocean-like Earth That was a long time ago, however. Mars is now covered in red dirt and rocks.
Jupiter: The record for the planet with the most moons goes to Jupiter, the largest planet on our solar system. Jupiter has 50 known moons. An additional 17 orbiting bodies are awaiting confirmation. Jupiter is not just the largest planet on our solar system; it is also the stormiest.
Saturn: Saturn is the most beautiful to look at. Perhaps it is the 7 rings surrounding Saturn that make it stand. Saturn’s rings are made of ice, dust, and rocks.
Uranus: Like Saturn, Uranus also has rings. But unlike Saturn, Uranus spins on its side. Uranus is also known as the ” ice giant” because it is so cold. Uranus reaches -224oC at its coldest.
Neptune: Neptune is so far out at the edge of our solar system that it takes Neptune 165 Earth years to orbit the Sun. Neptune at least 13 moons, but because it is so far away, we have no way of knowing exactly how many moons it has.
