A student compared data for four planets in the solar system. Based on the data, what conclusion can the student make about these planets?

• 
  Planets that have the shortest rotation period are closest to the Sun.

• The orbital period of a planet is related to its distance from the Sun.

• Planets that have the greatest orbital velocity are the farthest from the Sun.

• The rotational period of a planet is dependent upon its average distance from the Sun.

Answer explanation

Orbital Period = How long it takes a planet to make 1 complete trip around the Sun

Rotational Period = Amount of time it takes a planet to rotate once on its axis

Rotational Velocity = How fast a planet rotates

Orbital Velocity = How fast a planet orbits the Sun

The closer a planet is to the Sun the shorter the time it takes to make one trip around the Sun.

The farter a planet is from the Sun the longer the amount of time is to make one trip around the Sun.

A student builds a model of the solar system using metal hangers and styrofoam balls. The model would most likely help students to understand the ________.

• Composition of the planet

• Gravitational pull of the planet

• Order of the planets from the Sun

• Speed at which each planet orbit the Sun
