This object in space is much bigger than Earth. It is mostly gas and is generally round. It has many moons and is closer than Saturn to Earth.

Which of these is the student describing?

• Sun

• jupiter

• Venus

• Mars

What is the largest object in our solar system?

• Jupiter

• Neptune

• Sun

• Earth

Which object in our solar system does NOT orbit the sun?

• Planet

• Comet

• Moon

• Asteroid

A scientist discovered a new object in the sky that was orbiting the Sun. As it approached the Sun, a tail began to appear. Based on the observations, how should the scientist classify the object?

• an asteroid

• A Comet

• A Planet

• A Moon

What criteria did the student most likely use to separate the two sets of planets?

• planets with and without moons

• planets with water and planets without water

• Terrestrial planets and gas giants

• planets with atmospheres and planets without atmospheres

The chart below shows the periods of rotation of the inner planets. What can you conclude from the data in the table?

• A . day on Mars is longer than a day on Mercury.

• B. A day on Venus is longer than a day on Mercury.

• C. Earth and Mercury take the least time to complete one rotation.

• D. Mercury takes the longest time to complete one revolution.

What two things determine how strong gravity’s pull is between two objects?

• A. The mass of the objects and the distance between objects

• B. The size of the objects and the speed of the objects’ rotation.

• C. The distance between the objects and the speed of their revolutions

• D. The volume of the objects and the circumference of the objects

Why does the Moon orbit the Earth, instead of orbiting the Sun?

• Because Earth is much bigger than the Sun

• B. Because the Moon is so close to Earth it gets caught in Earth’s gravity.

• C. Because Earth is spinning faster than the Sun.

• .D. Because the Earth is orbiting faster than the Sun

How could the force of gravitational attraction between the Sun and Jupiter be increased?

• A. Reduce the mass of the Sun and Jupiter

• B. Reduce the distance between the Sun and Jupiter

• C. Reduce the speed of rotation of Jupiter

• D. Reduce the amount of radiation put out by the Sun.
