Our solar system

  1. 1. Our Solar System Pedro Vizcay o ¿no?
  2. 2. The Sun solar flare sun spots solar wind
  3. 3. MERCURYMercury, the planet nearest the Sun, is the second smallest planet in our solar system.It is only slightly larger than the Earths moon. The surface is covered with craters.This tiny planet does not have any rings or moons. evidence of craters
  4. 4. VENUSimpact craters lava flows Venus is one of the brightest objects in our sky, so it is clearly visible to the naked eye. It can be tricky to spot because it is always near the Sun. It rises and sets with the Sun each day. Ancient civilizations believed Venus was actually two different objects, so they called the one that rose the Morning Star, and the one that set the Evening Star.
  5. 5. EARTH and MOON What similarities and differences do you notice between the Earth and the Moon? Why do they have such different surface features?
  6. 6. MARS the night sky. It was named afterMars is very bright, which makes it easy to spot inthe Roman god of war because its reddish color reminded the people of blood. Olympus Mons is the largest volcano in our solar system! Although people have never landed on Mars, we have sent robotic explorers there. Martian crater
  7. 7. ASTEROID BELTMost asteroids can be found in the Asteroid Belt, which is located betweenMars and Jupiter. Asteroids are rocky and metallic objects that orbit the Sun,but are too small to be considered planets. They are known as minor planets.Asteroids range in size from Ceres, which has a diameter of about 1000 km,down to the size of pebbles.
  8. 8. JUPITERJupiter, the fifth planet from the Sun, is the largest planet in our solar system.Jupiter is so big that over 1,000 planets the size of Earth could fit into it.It has over 60 moons and 2 rings. Can life exist on Jupiters moon, Europa? The “Great Red Spot” Is actually a huge Storm system! Here are a few of Jupiter’s moons
  9. 9. SATURN planet in our solar system.Saturn, the sixth planet from the Sun, is the second largestIt is often called the ringed planet because many rings of dust and rocks surround it.Saturn also has over 31 moons. Saturn with some of its moons Some of Saturn’s rings Titan is a moon of Saturn that may have some Conditions necessary for life! The picture on the right shows an artist’s drawing of how Titan might have looked when the Cassini-Huygen’s probe dropped into its atmosphere in Dec., 2004.
  10. 10. URANUSUranus is a very unusual planet because it sits on its side with north and southpoles sticking out the sides. It rotates around this axis, making it look like a ballrolling around in a circle around the Sun. some of Uranus’s moonsBlack rings
  11. 11. NEPTUNENeptune, usually the eighth planet from the Sun, is a very cold place.Occasionally, Pluto crosses Neptune’s orbit and becomes the eight planet.Its bluish color comes from its atmosphere of methane gas. Tiny Dark Moon
  12. 12. PLUTOPluto, usually the ninth planet from the Sun, is the smallest planet in our solar system.Some scientists believe that Pluto once was one of Neptune’s moons, and that itpulled out away from Neptune and made its own orbit. Clearest view to date Of Pluto and Charon
  13. 13. COMETSComets are sometimes called dirty snowballs or "icy mudballs".They are a mixture of ices (both water and frozen gases) and dust that forsome reason didnt get incorporated into planets when the solar system was formed.This makes them very interesting as samples of the early history of the solar system. Comets have elliptical orbits. When we see a comet, we are seeing the tail of the cometComet Halley in 1910 as comes close to the Sun.
