Which planet has a shorter year than its day?

Back

Venus has a shorter year (Period of Revolution) than its day (Period of Rotation).

Front

What keeps the planets in orbit around the Sun?

Back

The planets are kept in orbit around the Sun by the combined effects of gravity and inertia.

How do the sizes of inner planets compare to outer planets?

Back

The inner planets are smaller than the outer planets.

Front

What is the largest planet in the Solar System?

Back

Jupiter is the largest planet in the Solar System.

Front

What is the period of revolution?

Back

The period of revolution is the time it takes for a planet to complete one full orbit around the Sun.

Front

What is the period of rotation?

Back

The period of rotation is the time it takes for a planet to complete one full spin on its axis.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.
