Problem 1. The Sun as seen from Earth has an apparent magnitude of -26 in the B-band. 1. What is the Sun's absolute magnitude (in the B-band)? 2. What would its apparent magnitude be as seen from Jupiter? (Jupiter is approximately 5.2 AU from the Sun.) 3. At a certain distance d from a Star A, its apparent brightness is f. If we were to travel at a relativistic velocity to a point in space which is 5 times further away, how much fainter would the star appear to us? (i.e. what fraction of its original apparent brightness would it now appear to us?)
