there is about 2 x 10^18 g/s (grams/second) of asteroid material would need to fall into the sun in order to match its output power of 4 x 10^26 W. For another star that has a radius of 5 solar radii, a mass of 2 solar masses, and an output power of 3 x 10^25 W, how many grams per second of asteroid material would need to fall into it in order to match it's output power? Use the equation: E = GM star M asteroid/R star
