Alien scientists discover an asteroid headed directly towards their planet. The alien planet has a mass of M=6.39x1023 kg and the asteroid has a mass of m=1.50x108 kg. When the asteroid is a distance r1=3.40x108 m from the center of the alien planet, it has a velocity v1=1.00 m/s. The alien scientists calculate it will hit the surface of the planet with velocity v0=4982.00 m/s. What is the radius of the alien planet?
