1. What is the orbital radius of the Earth? What is another name for this distance? Express this distance in both AU and km. Draw a picture of the Earth orbiting the Sun to help you answer this question.
2. What is the orbital period of the Earth? Express this answer in both years and seconds.
3. Using the information from questions 2 and 3, we can calculate the orbital velocity of the Earth for comparison with the orbital velocity of the asteroid. Velocity can be calculated by using this equation: velocity = distance / time. Using the orbital radius of the Earth, divide the circumference of the Earth’s orbit (2 π ROE ) with its orbital period ( T ) in seconds to determine the earth’s orbital velocity. VO = 2 π ROE / T
