A small spinning asteroid is in a circular orbit around a star, much like the earth's motion around our sun. The asteroid has a surface area of 9.5 m2. The total power it absorbs from the star is 4600 W. Assuming the surface is an ideal absorber and radiator, calculate the equilibrium temperature of the asteroid.
