  1. STARS & PLANETS

  2. DEFINITIONS- Solar System- Sun & all objects that are gravitationally bound to the Sun. Star- enormous hot ball of gas held together by gravity. Planet- an object which revolves around a star. Moon- an object which revolves around a planet. Satellite- any object which revolves around another object. Asteroid- rocky body too small to be a planet.

  4. INNER PLANETS: Terrestrial (rocky)- OUTER PLANETS: Gas Planets:

  5. Mercury- • -- Rocky & cratered. • - No moons. • - No atmosphere. • - Surface temperature: • -170 - 400 C.

  6. Venus- • - Rocky. • - No moons. • - Closest to Earth. • - Retrograde rotation. • - Atmosphere is mostly • carbon dioxide. • - Avg. surface temp.: 460 C

  7. Earth- • - Rocky. • - One moon. • - Only planet with life. • - Only planet with water. • - Avg. surface temp.: 10 C. • - Seasons due to tilt on axis.

  8. Mars- • -- Rocky. • - Has 2 moons. • - Atmosphere thin CO2. • - Polar ice caps. • - Volcanoes & canyons. • - Has seasons. • - Avg. surface temp.: -50 C.

  9. Jupiter- • -- Gas giant. • - 63 moons + faint rings. • - Mass greater than all • other planets combined. • - No solid surface. • - Composed mainly of: • hydrogen & helium. • - Great Red Spot.

  10. Saturn- • -- Gas giant. • - 47+ moons, rings of rock & ice. • - Like Jupiter has rapid rotation, • thus it has many storms.

  11. Uranus- • -- Gas giant. • - 27 moons plus rings. • - Atmosphere mostly • hydrogen & helium. • -- Retrograde rotation.

  12. Neptune- • -- Gas giant. • - 13 moons plus rings.

  13. DIFFERENCE BETWEEN PLANETS & STARS: STARS- every star in the sky is a SUN; stars produce their own light by nuclear fusion. PLANETS- reflect light from the stars.

  14. Sun- Medium sized star Center of our solar system Part of the Milky Way Galaxy One of many stars in our galaxy
