Solar System

The zone just before the surface. Heat is transfered by rising hot plasma and sinking cooler (but still hot) plasma

Composed of dust, gas, and ice. A vast majority of these are contained in the Kuiper Belt or Oort Cloud.

Small rocky planet

All of the terrestrial planets have at least one moon.

Similar in size to asteroids, but with a compostion similar to a comet.

Spherical shell of icy debris, well beyond the outermost planets. Where comets originate.

Retrograde rotation means a planet rotates in a different direction from its orbit. An example is...

Gas giants and Stars spin faster at the equator than at the poles. This is known as...

This layer is just above the surface of the sun. Jets of plasma, called spicules might be seen here.

These objects, located within the rings of saturn helps the rings retain their shape.

Which is not a charateristic of a planet?

A small rocky body that orbits the sun. Most are found in a belt between mars and jupiter. (Vesta is the largest)

How many planets in our solar system have rings?

The surface of the sun

The outer most layer of the sun. Extends into space and becomes the solar winds.

The center of the sun. Nuclear Fusion takes place here.

A near-earth object that is of sufficient size to cause significant damage in the event of an impact with the earth

An object’s spin on its own axis.

Path an object takes as it revolves about another object.

Gas giant planets

Which is not necessarily true about all dwarf planets?

Ring of material beyond Neptune. Most dwarf planets are found here.

Often the remains of a comet, these small rocky bodies range from sand size up to about a meter in diameter.

Second layer from the center of the sun. Energy transferal takes place very slowly.

Rocky bodies that may be found at the lagrange points of a planet.
