Let the speed of second asteroid is v.
The gravitational force between the two asteroids is balanced by the centripetal force on the second asteroid.
Where, G be the universal gravitational constant.
G = 6.67 x 10^-11 Nm^2/kg^2
v = 1.81 x 10^-4 m/s
Simply draw the vector with the given coordinates.
