The speed of an asteroid at aphelion is va = 10 km/s and at perihelion is vp = 20 km/s. What is the relationship between the aphelion radius ra to perihelion radius rp?
ra = 4 rp
Correct: ra = 2 rp
ra = √2 rp
ra = rp / 2
ra = 3rp
The orbital radius of an asteroid at aphelion is ra = 200000 km and a perihelion is rp = 80000 km. What is the aphelion speed if the perihelion speed is 10 km/s?
