The Solar System


Overview of solar system

Overview of Solar System

  • Solar system: a group of objects in space that move around a central star

    • The SUN

  • Planets: large objects that moves around a star

    • travel in paths called orbits around the sun

      • Counter-clockwise

    • How many? 8 or 9?

    • Most have at least 1 moon (natural satellite)

    • Some have rings

Overview of Solar System

  • Asteroids and Comets also move around the sun

    • Asteroids- small and rocky, made of metal and carbon, found mostly between paths of Mars and Jupiter

    • Comets- made up of dust and ice


Grouping planets

Grouping Planets

Planets divided into 2 groups

  • Inner: Mercury, Venus, Earth, & Mars

  • Outer: Jupiter, Saturn, Uranus, Neptune, Pluto

    * Separated by asteroid belt

Grouping planets1

Grouping Planets

Two other ways to group planets:

  • Composition-what the they’re made of

    -Rocky planets:Mercury, Venus, Earth, Mars, Pluto

    *heavy, move slowly, no rings, few moons

    -Gas planets:Jupiter, Saturn, Uranus, Neptune

    *light, move quickly, rings, lots of moons

  • Size

    -Small:Mercury, Venus, Earth, Mars, Pluto

    -Giant:Jupiter, Saturn, Uranus, Neptune


Mnemonic device

Mnemonic Device

  • A sentence that helps us memorize a string of words

    • Examples?

  • Will help us remember the order of the planets from the sun out

    • My Very Earnest Mother Just Served Us Nine Pickles

      • Every 248 years, Neptune becomes the farthest planet for 20 years
