The data table provides information on the distance and period of orbit for the inner planets.

Based on the pattern in the data, we can predict that the period of Mars’ orbit will be–

• less than 88 days.

• between 88 and 224.6 days.

• greater than 365.2 days.

• exactly two times 224.6 days.

Which of the following best describes the formation of the solar system?

• The sun ejected rocky material which later went on to form the planets.

• A rotating disk of gas and dust was drawn together by the force of gravity.

• One very large planetary body broke apart into several smaller planets.

• Several stars of different masses cooled and formed the planets and the sun.

Earth and its solar system are a part of which of the following galaxies?

• Andromeda

• Black Eye

• Milky Way

• Cartwheel

Students are making a model of planetary motion. The students tie a tennis ball to a string. The string passes through a spool and is attached to a 1 kilogram mass.

The mass pulls down on the string as the students spin the tennis ball around the spool. If the students wish to change the model to show what would happen if the sun had a greater gravitational pull, what change should they make?

• Spin the tennis ball at an increased speed

• Replace the 1 kg mass with a 2 kg mass

• Tie the tennis ball with a longer string

• Change the spool to a longer one
