  1. Space Facts Section B – The Planets

  2. Mercury • Closest planet to the Sun • Takes the least amount of time to orbit the Sun • Not large enough for its gravity to hold onto a moon or much of an atmosphere. • No Moons

  3. Venus • The surface is hot (869) and the atmosphere is dense and contains carbon dioxide and sulfuric acid. • Second planet from the Sun

  4. Earth • Has volcanic eruptions and earthquakes. • Sunlight, a nitrogen and oxygen-rich atmosphere • Large oceans and the greenhouse effect makes climates that supports life. • Third planet from the Sun.

  5. Mars • The largest canyon in the solar system • Called the Red Planet • Valles Marineris, is as wide as the United States. • Might have had running water at one time. Has ice caps • Largest volcano in the solar system, Olympus Mons

  6. Jupiter • The largest planet has an atmosphere of cold hydrogen gas. • It has many moons, so far 17 have been found. • It has a giant red spot that is thought to be a storm

  7. Saturn • Mostly gas, but less dense, making it very light that it could float on water. • It has 18 moons. • It is known for its beautiful rings which are made of millions of bits of ice.

  8. Uranus • Atmosphere of methane gas • set of dark, narrow rings that run from top to bottom, instead of around.

  9. Neptune • Is the bluest planet because of its methane gas atmosphere • Its moon, Triton, has volcanoes • Crosses Pluto’s path as it orbits the Sun • Has a set of dark rings

  10. Pluto • Does not have a thick atmosphere • Discovered in 1930 • Has one moon called Charon • Smallest planet • Covered by layers of ice

  11. Asteroids • A wide belt of small objects that orbit the Sun between Mars and Jupiter. • Sometimes called minor planets. • Might be the remains of planets pulled apart or leftovers from the formation of the solar system

  12. Meteors • Parts or pieces of meteoroids that fall from space • No bigger than a grain of sand • Sometimes called a Shooting star.

  13. Meteoroids • Part of the dust and gas trail left behind by a comet

  14. Meteorite • A piece of rock that falls and lands on the Earth from space

  15. Comets • These are chunks of ice and rock left over from the formation of our solar system • They move around the Sun in a long oval-shaped orbits

  16. How are meteors related to comets? • Meteors are the dust and rock particles that fall from the tail of a comet

  17. Scientist attempt to find out if there is other intelligent life in the universe • Scientist use radio telescopes to try to detect signs of life sending coded messages called SETI into space
