The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter. Wikipedia
Age: 4.571 billion years
Stars: 1 (Sun)
Known planets: 8 declared by IAU: Mercury; Venus; Earth; Mars; Jupiter; Saturn; Uranus; Neptune
Nearest known planetary system: Proxima Centauri system (4.2441 ly)
Location: Local Interstellar Cloud, Local Bubble, Orion–Cygnus Arm, Milky Way
Known natural satellites: 657 (206 planetary; 451 minor planetary);
Known comets: 4,402

  1. 1. Our Solar System
  2. 2. Sun Hi everyone I am sun. I am like the heart of the solar system. I am made up of extremely hot gases. I am the ultimate source of heat and light for the planets.
  3. 3. Planets Know we are going to teach about our planets.
  4. 4. Mercury I am the smallest planet in our solar system. I'm just a little bigger than Earth’s moon. I am the closest planet to the sun, but actually not the hottest. Venus is hotter
  5. 5. Venus Hi everyone, I am Venus, I am the second nearest planet from the sun. I am closer to Earth than to the Moon. As I am nearest to the sun I am only seen in the hours near sunrise or sunset. I am also called Earth’s twin as I am very much similar to Earth in size and shape.
  6. 6. Earth I am your home planet Earth, a rocky, terrestrial planet. I have a solid and active surface with mountains, valleys, canyons, plains and so much more. I am special because i am an ocean planet. Water covers 70% of my surface.
  7. 7. Mars I am the forth nearest planet from the sun. I am sometimes called the red planet because of rusty iron in the ground. Like earth, I have season, polar ice caps, volcanoes and weather. I have a very thin atmosphere made up of carbon dioxide, nitrogen and argon. I am named after the Roman God of War
  8. 8. Jupiter I am the largest planet in the solar system; bigger than all the other planets put together. I am the fifth planet from the Sun. I am so huge that I contain more than 1,000 Earths. I am a kind of planet called a gas giant, consisting almost entirely of gases, mainly hydrogen and helium.
  9. 9. Saturn l am not the only planet to have rings, but definitely has the most beautiful ones. The rings you see are made of groups of tiny ringlets that surround Saturn. They’re made of chunks of ice and rock. Like Jupiter, I'm mostly a ball of hydrogen and helium.
  10. 10. Uranus l am made of water, methane, and ammonia fluids above a small rocky centre. My atmosphere is made of hydrogen and helium like Jupiter and Saturn, but also has methane. The methane makes me blue.
  11. 11. Neptune l am dark, cold, and very windy, the last of the planets in our solar system. I am more than 30 times as far from the sun than earth .I am very similar to Uranus, made of a thick fog of water, ammonia, and methane over an Earth-sized solid centre. My atmosphere is made of hydrogen, helium, and methane. The methane gives me the same blue colour as Uranus. I have six rings, but they're very hard to see.
