Review: Orbital Motions and Moon

Match the following

• Jupiter, Saturn, Uranus, Neptune

• Going around the sun.

• Mercury, Venus, Earth, Mars

• Outer Jovian planets

• rotation

• Spinning on its axis.

• revolution

• Inner terrestrial planets

According to your ESSRT, the terrestrial planets differ from the Jovian planets because the terrestrial planets are

• less dense and larger

• less dense and smaller

• more dense and larger

• more dense and smaller

The green dot represents (a)   .

The red line represents (b)   .
The purple dot and the (c)   are foci.

• perihelion
• major axis
• Sun
• semi major axis

• aphelion

• white dot

• black dot
