We are given with

M = mass of planet

R = radius of circular trajectory of the satellite

ms = mass of the station

mm = mass of the meteorite

ms = 10 mm

R/2 = new orbit distance

The speed of the meteorite can be solved using the law of conservation of momentum

ms vs + mm vm = (ms + mm) v

Since the new orbit distance is half the original

v = 2 vs

Substitute and solve for vs
