  1. Solar System

  2. Planet: a celestial body that orbits one or more stars • Solar system: a group of planets circling one or more stars • Revolution: one “turn” around the sun • Rotation: one “spin” of a planet • Axis: the centre line a planet spins around

  3. The Sun • The centre of the solar system • The sun contains more than 99% of the mass of its solar system • Our sun is mostly made of hydrogen gas • Our sun is so large it would take 110 earths lined up to reach the sun’s width

  4. Features of the sun

  5. Solar Wind • Sometimes energetic gases burst on the surface of the sun sending a wave of high energy particles past earth • This wave is called solar wind • When these particles come into contact with the atmosphere at the poles they collide with particle there and create the northern lights

  6. Moons • An object that orbits around a planet is known as a “satellite” • One of our natural satellites is our moon

  7. Asteroids • Smaller than planets or moons, asteroids are chunks of rock orbiting our sun (and other suns) • They are believed to be the left over remains from the formation of the solar system • They range in size from a grain of sand to 1000 km wide

  8. Comets • Made of ice, rock and gas (though mostly rock) • They hurtle through space at high speeds and leave a trail of gas and dust behind them

  9. Trans-Neptunian Objects • Anything orbiting our sun way out past the planet Neptune are known as Trans-Neptunian objects • Often called “Dwarf planets”

  10. Kuiper belt and Oort cloud • Two possible sources of comets • Kuiper belt is a flat disk of millions of small bodies orbiting the sun • Oort cloud is a spherical cloud of small icy fragments orbiting at the farthest reaches of the sun’s gravity
