2. Our solar system Our Solar System is made out of eight planets and the Sun. The Sun is in the centre of our solar system and the eight planets are orbiting it. There are eight planets in our solar system that are:

4. One of the biggest Stars is the Sun. The Sun is a ball of fire which is over 6,000 ̊C. The Sun was born 4.6 billion years ago. The Sun is Gigantic and very bright. It is bigger than 1,000 Earths, it is even known as an ordinary star. There are a lot of bigger stars than the sun and the biggest one is Arctorus. The sun

5. TheSun is 70% hydrogen , 28% helium and 2% metal. It has a lot of gravity enough to hold the eight planets. The sun has enough fuel for another 5 billion years. After that, the earth will be known as the black dwarf. Luckily for us we won’t be here and we won’t freeze to death. The Sun is 93 million miles from earth, that means the sun has lots of energy because it takes 8 minutes for the sun’s brightness to reach our eyes. Imagine there’s no sun - we would be in total darkness and we wouldbevery cold.

6. Mercury is the closest planet to the sun. It circles the sun faster than all the other planets, which is why Romans named it after the swift-footed messenger god Mercury. As the planet nearest the sun, the surface of Mercury can reach a scorching 840 degrees. Mercury is the smallest planet, it is only slightly larger than Earth's moon. Since it has no significant atmosphere to stop impacts, the planet is pockmarked with craters. For instance, about 4 billion years ago, a roughly 60-mile-wide (100-kilometre-wide) asteroid struck Mercury Mercury

7. Venus Venus is the second planet away from the Sun and the sixth largest. Venus’ orbit is the most circular of any planet. Venus is the goddess of love and beauty. The planet is so named probably because it is the brightest of the planets known to the ancients. It is the Earth’s twin planet. It's extremely hot and deadly atmosphere makes it impossible for any human or astronaut to explore itssurface. Its atmosphere is made up mostly of carbon dioxide. Venus rotates so slowly that it orbits the sun faster than it can make one whole rotation on its axis. In other words, Venus has a longer day than year.

8. Earth Earth is our home planet and it is the third planet away from the sun and the fifth largest in the solar system. The Earth weighs 6,588,000,000,000,000,000,000,000 tons. 70% of the Earth is water and the rest is land. The earth rotates on its axis more slowly in March than in September. The world is not round. It is an oblate spheroid, flattened at the poles and bulging at the equator.

9. Mars Mars is the only planet whose surface can be seen in detail from the Earth. It is reddish in color, and was named after the bloody red God of war of the ancient Romans. Mars is the fourth closest planet to the Sun. Mars is a small rocky body once thought to be very Earthlike. Like the other terrestrial planets Mercury, Venus, and Earth—its surface has been changed by volcanism, impacts from other bodies, movements of its crust, and atmospheric effects such as dust storms.

10. Asteroid belt Space Asteroids are made of rock and metal, mostly nickel and iron.The Asteroid Belt is a region between the inner planets and outer planets where thousands of asteroids are found orbiting around the Sun. Ceres is the largest asteroid in the asteroid belt and is the only dwarf planet in the belt.

11. Jupiter Jupiter is the largest planet in our Solar System. Ancient Astronomers named Jupiter after the king of the Roman Gods. Jupiter is the 5th closest planet to our sun. Jupiter's volume is large enough to contain 1,300 planets the size of Earth. Jupiter rotates faster than any planet in the Solar System. It rotates so quickly that the days are only 10 hours long. But it takes 12 Earth years for Jupiter to complete an orbit around the sun. The great red spot on Jupiter is a storm that has been going on for over 300 years. You can fit 100 Earths into Jupiter's great red spot. Jupiter has a ring just like Saturn and Uranus.

12. Saturn Saturn is the second largest planet. Only Jupiter is larger. Saturn has seven thin, flat rings around it. A couple of planets have rings, but their rings are much fainter than those around Saturn. The planet can be seen from Earth with the unaided eye, but its rings cannot. Saturn was the farthest planet from the earth that the ancient astronomers knew about. They named Saturn after the Roman God of agriculture.

13. Uranus Uranus is the seventh planet from the sun and is named after the Greek God of the sky in Latin. It is the only planet whose name came from a figure in Greek mythology as opposed to Roman mythology. Because of the strange way it spins, nights on some parts of Uranus can last for more than 40 years. Even though Neptune is further from the sun, Uranus is the coldest planet in the solar system.Uranus and Neptune are both known as Ice Giants.

14. Neptune Neptune is the stormiest planet. The winds there can blow up to 1,240 miles per hour, that is three times as fast as Earth's Hurricanes. Neptune is a sea blue color due to the methane gas in its atmosphere. It once had a great dark spot similar to Jupiter. Neptune only receives 1/900 of the solar energy that reaches Earth. Neptune has its own heat source, it emits a quantity of energy 2.7 times greater than it receives. Neptune has 8 known moons. It is 30 times farther from the sun as is the Earth .It goes around the sun once every 165 Earth Years. The atmosphere is made up of Hydrogen, Helium and Methane. Neptune has a rocky core.

15. Bye. Thanks for watching.
