Question

State whether true or false.

If a heavenly object like an asteroid or a planetoid revolving around the sun moves into an orbit of smaller radius, its speed increases.

• A. True
• B. False

Answer 1

The correct option is A True

If a heavenly body like an asteroid or a planetoid revolving around the sun moves into an orbit of smaller radius, then its semi-major axis of its orbit reduces.

According to keplar's third law, thus the square of its period which is directly proportional to the cube of the semi major axis of its orbit reduces too, thus increasing its speed.
