  1. The Solar System Grade Level 3

  2. FUN FACTS! • All the solar system facts provided in this power point are provided by NASA Office of Space Science • Visit them @http://solarsystem.nasa.gov/features/planets_profiles.html

  3. Today’s Objective: • TEKS: (3.1) Science concepts: The student knows that the natural world includes earth materials and objects in the sky. The student will be able to identify all the planets in our solar system and their position in relation to the sun.

  4. Mercury

  5. Mercury • The small and rocky plant Mercury is the closest planet to the sun; it speeds around the sun in a wildly elliptical (non-circular) orbit that takes it as close as 47 million km and as far as 70 million km from the sun. • Mercury completes a trip around the sun every 88 days, speeding through space at nearly 50 km per second, faster than any other planet. • Because it is so close to the sun, temperatures on its surface can reach a scorching 467 degrees Celsius. • Mercury is the second smallest planet in the solar system, larger only than Pluto.

  6. Venus

  7. Venus • If Earth had a twin, it would be Venus, the second planet from the sun. • The two planets are similar in size, mass, composition and distance from the sun. But there the similarities end. • Venus has no ocean. Venus is covered by thick, rapidly spinning clouds that trap surface heat, creating a scorched greenhouse-like world with temperatures hot enough to melt lead. • These clouds reflect sunlight in addition to trapping heat. Because Venus reflects so much sunlight, it is usually the brightest planet in the sky .

  8. Earth

  9. Earth • Earth is our home planet, and is the only planet in our solar system known to harbor life-life that is incredibly diverse. • All of the things we need to survive are provided under a thin layer of atmosphere that separates us from the uninhabitable. Air, water, land, and life- including humans. • Earth is the third planet from the sun and the fifth largest in the solar system. • The four seasons are a result of Earth’s axis of rotation being tilted more that 23 degrees.

  10. Mars

  11. Mars • The red planet Mars is the fourth planet from the sun. • Mars also has two small moons named Phobos and Deimos. • Mars attracts intense scientific interest, in which people on Earth have fancied Mars to be the source or home of hostile invaders. This of course is not true and has not been proven.

  12. Jupiter

  13. Jupiter • Jupiter is the fifth planet from the sun. • Jupiter is the most massive planet in our solar system, and in composition it resembles a small star. • With its numerous moons (39) and several rings, the Jupiter system is a “mini-solar system”. • At first glance, Jupiter appears striped. These stripes are dark belts and light zones created by strong east-west winds in Jupiter’s upper atmosphere.

  14. Saturn

  15. Saturn • Saturn is the sixth planet from the sun • Like the other giant plants (Jupiter, Uranus, and Neptune) Saturn is a gas giant made mostly of hydrogen and helium. • Saturn is the most extensive and complex planet in our solar system. • NASA’s two Voyage spacecrafts revealed that Saturn’s rings are made mostly of water ice, and they found “braided” rings, ringlets and “spokes”-in the rings that seem to circle the planet at a different rate from that of the surrounding ring material.

  16. Uranus

  17. Uranus • Uranus is the seventh planet from the sun • Once considered one of the blander-looking planets, Uranus has been revealed as a dynamic world with some of the brightest clouds in the outer solar system. • Uranus has 11 rings and 8 moons • Uranus gets its blue-green color from methane gas above the deeper cloud layers (methane absorbs red light and reflects blue light). • Uranus is classified as a “gas giant” planet because it has no solid surface. • Uranus has at least 20 moons which all are mostly named after works of Shakespeare and Alexander Pope.

  18. Neptune

  19. Neptune • Neptune is the eighth planet from the sun • Neptune was the first planet located through mathematical predictions rather than through regular observations of the sky. Discovered in 1846. • Nearly 4.5 billion kilometers from the Sun, Neptune orbits the Sun once every 165 years, and therefore it has not quite made a full circle around the sun since it was discovered. • Neptune is invisible to the naked eye because of its extreme distance from Earth.

  20. Pluto

  21. Pluto • Pluto is the ninth and furthest planet from the sun • Pluto has long been considered to be the smallest and coldest planet in the solar system • Pluto may also be the largest of a group of objects that orbit in a disk-like zone of beyond the orbit of Neptune called the Kuiper Belt. • Discovered by American astronomer Clyde Tombaugh in 1930, Pluto takes 248 years to orbit the sun.
