Solar system
The document provides facts about objects in our solar system including the Sun, planets Mercury through Neptune, dwarf planets, asteroids, and the Kuiper Belt. It notes key details about each such as the Sun containing 99% of the solar system's mass, Venus rotating backwards compared to other planets, Jupiter having the largest moon Ganymede, Saturn being the ringed planet, and the Kuiper Belt potentially containing over a trillion comet nuclei. It aims to inform readers about characteristics of astronomical bodies in our neighborhood.

- 2. Facts about Sun TheSun contains 99% of the total mass of the solar system. One million Earths could fit inside the Sun Eventually, Sun will consume the Earth The Sun will one day be about the size of Earth. The sun is an almost perfect Sphere Light from the Sun takes 8 minutes to reach Earth The sun is middle-aged It has a very strong magnetic field It generates solar wind
- 3. Facts about Mercury onlythe second hottest planet. the most cratered planet in the Solar System. Only two spacecraft have ever visited Mercury. named for the Roman messenger to the gods. Mercury is hot, but not too hot for ice the closest planet to the sun and due to its proximity it is not easily seen except during twilight A year on Mercury is just 88 days long. the smallest planet in the Solar System. the second densest planet. has wrinkles. has a molten core:
- 4. Facts about Venus Venusis the second planet from the sun and is the second brightest object in the night sky after the moon A day on Venus lasts longer than a year. Venus is often called the Earth’s sister planet Venus rotates in the opposite direction to most other planets. Atmospheric pressure on Venus is 92 times greater than the Earth’s. Venus is the hottest planet in our solar system. More than 1,000 volcanoes or volcanic centre's larger than 20 km have been found on the surface of Venus The Russians sent the first mission to Venus. Venus doesn’t have any moons, and we aren’t sure why
- 5. Earth The Earth’s rotation is gradually slowing oncebelieved to be the centre of the universe. has a powerful magnetic field. There is only one natural satellite the only planet not named after a god. the densest planet in the Solar System the largest of the terrestrial planets
- 6. Mar s home of the tallest mountainin the solar system Mars has the largest dust storms in the solar system. Pieces of Mars have fallen to Earth.. Mars takes its name from the Roman god of war There are signs of liquid water on Mars. One day Mars will have a ring.
- 7. J Jupiter Jupiter Sucks Up Space Garbage Jupiteris the fourth brightest object in the solar system. Jupiter is a great comet catcher. has the shortest day of all the planets. Jupiter orbits the Sun once every 11.8 Earth years. Jupiter has unique cloud features The Great Red Spot is a huge storm on Jupiter
- 8. Jupiter’s moon Ganymede isthe largest moon in the solar system Jupiter’s interior is made of rock, metal, and hydrogen compounds. Jupiter has a thin ring system. Eight spacecraft have visited Jupiter. Jupiter has the shortest day of all the planets.
- 9. the fifth brightest object inthe solar system. The Ringed Planet gives off more energy than it receives from the Sun It takes Saturn 29.4 Earth years to orbit the Sun has the fastest winds of any other planet in our solar system the least dense planet in the solar system has 150 moons and smaller moonlets Saturn’s moon Titan is the second largest moon in the Solar System, behind Jupiter’s moon Ganymede the flattest of the eight planets Saturn
- 10. William Herschel discoveredUranus in 1781 Uranus rotates on its axis once every 17 hours and 14 minutes It takes Uranus 84 Earth days to orbit the Sun Uranus wind speeds can reach up to 900 km per hour The mass of Uranus is about 14.5 times the mass of Earth Uranus is the second least dense planet in the solar system, after Saturn. The Voyager 2 is the only spacecraft to have flown by Uranus. has 13 presently known rings Uranus is the coldest planet in the solar system. The Uranian moons are named for characters created by Alexander Pope and William Shakespeare (Oberan, Titania and Miranda) Uranus
- 11. Spins on its axisrapidly has a very active climate Has a very thin collection of rings (5) Voyager 2 was the only spacecraft that flown to Neptune The smallest of the ice giants Has 14 moons (Triton the biggest moon) Discovered by Urbain Le Verrier and Johann Galle Neptune
- 12. Additional info…. There are5 officially recognized dwarf planets in our solar system: 1. Ceres (located in the asteroid belt) 2. Pluto 3. Haumea 4. Makemake 5. Eris There are 6 objects in our solar system that are almost certainly dwarf planets and there may as many as 10,000. Ceres and Pluto have been visited by space probes (NASA’s Dawn and New Horizons)
- 13. Facts about AsteroidBelt Asteroid Belt objects are made of rock and stone. Some are solid objects, while others are orbiting “rubble piles”. The Asteroid Belt contains billions and billions of asteroids. Some asteroids in the Belt are quite large, but most range in size down to pebbles. The asteroid 1/Ceres is also designated as a dwarf planet, the largest one in the inner solar system. The Asteroid Belt may contain many objects, but they are spread out over a huge area of space. This has allowed spacecraft to move through this region without hitting anything. Asteroids get their names from suggestions by their discoverers and are also given a number. The formation of Jupiter disrupted the formation of any worlds in the Asteroid Belt region by scattering asteroids away. This caused them to collide and break into smaller pieces. Gravitational influences can move asteroids out of the Belt.
- 14. Facts about KuiperBelt There could be more than a trillion comet nuclei in the main body of the Kuiper Belt. The largest Kuiper Belt Objects are Pluto, Quaoar, Makemake, Haumea, Ixion, and Varuna. These are often also referred to as Trans-Neptunian Objects (TNOs). Astronomers have found structures similar to our Kuiper Belt around at least nine other stars. Hubble Space Telescope imaged discs around the stars HD 138664 in the constellation Lupus, and HD 53143 in the constellation Carina. The ices in the Kuiper Belt date back to the formation of the solar system. They contain clues to conditions in the early solar nebula
