Meteors moons asteroids comets

  1. 2. <ul><li>Small icy Solar System body that when close enough to the sun displays a coma </li></ul><ul><li>Comets have a wide range of orbital periods between a few years to hundreds of years </li></ul><ul><li>Short period comets originate in the Keuiper Belt </li></ul><ul><li>Longer period comets originate in the Oort Cloud, a spherical cloud of icy bodies in the outer solar system </li></ul><ul><li>Comets are distinguished from asteroids by the presence of a coma or tail </li></ul>
  2. 3. <ul><li>Class of small solar system bodies in orbit of the Sun </li></ul><ul><li>&quot;asteroid&quot; was historically applied to any astronomical object orbiting the Sun that was not observed to have the characteristics of an active comet or a planet </li></ul><ul><li>Asteroids are believed to the remnants of planetesmials </li></ul><ul><li>The large majority of known asteroids orbit in the main asteroid belt between the orbits of Mars and Jupiter </li></ul>
  3. 4. <ul><li>A meteoroid is a sand- to boulder-sized bit of remains in the Solar System. The observable path of a meteoroid that enters Earth's (or another body's) atmosphere is called a meteor, or colloquially a shooting star or falling star . </li></ul><ul><li>The definition of a meteor is a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom </li></ul>
  4. 5. <ul><li>A moon is a celestial body that orbits a planet or smaller body which is called its primary </li></ul><ul><li>As of July 2009, 336 bodies are formally classified as moons. They include 168 orbiting six of the eight planets, 6 orbiting three of the five dwarf planets, 104 asteroid moons, and 58 satellites of Trans-Neptunian objects </li></ul><ul><li>The natural satellites orbiting relatively close to the planet on prograde orbits (regular satellites) are generally believed to have been formed out of the same collapsing region of the protoplanetary disk that created its primary </li></ul>
  5. 6. <ul><li>What would happen if we hade more then one moon? </li></ul><ul><li>The tides on Earth would definitely be affected by the presence of other moons, because the Moon is the reason why we experience tides at all. If they were a 2nd moons around Earth, the amplitude of the tides might be larger or smaller, since the effects of each other could partially cancel out or add up. </li></ul><ul><li>What would happen if the moon moved farther away from Earth? </li></ul><ul><li>The tides would change and the floods would be about 2.5 times lower then normal. </li></ul>
