Answer to Question 1

TRUE

Answer to Question 2

By watching it long enough to find its period of revolution around the Sun, we can use Kepler's third law to get the average distance by squaring the period in years, then finding the cube root of this value for the average distance of the asteroid from the Sun in astronomical units.
