Mini-Quiz: Kepler's Laws of Orbital Motion

by Ron Kurtus (revised 29 October 2007)

Take this Mini-quiz to check your understanding of the lesson material.

1. Could a satellite orbit the Earth in a circle?

Yes, but it is a special case

No, because the Earth is not a perfect sphere

Only during a Full Moon

2. What happens when the Earth's orbit brings it closer to the Sun?

The Earth heats up with global warming

It never gets closer, since the orbit is a perfect circle

The Earth speeds up in its orbit

3. Since Mars is 1.67 AU from the Sun, how long does it take to orbit the Sun?

Twice as long as Jupiter

2.1 Earth years

1 Earth year

If you got all three correct, you are on your way to becoming a Champion in Astronomy. If you had problems, you had better look over the material again.
