Question

1. which factor does not affect a stars absolute magnitude (luminosity)? a) the stars distance. b) the stars size. c) the stars temperature. d) the stars shape.

Explanation:

The absolute magnitude (luminosity) of a star is an intrinsic property related to the amount of energy it emits. Size affects the surface - area from which energy is radiated, temperature affects the rate of energy generation through nuclear fusion, and distance affects the apparent magnitude but not the absolute magnitude. The shape of a star has a negligible effect on its overall energy - emitting capacity and thus does not affect its absolute magnitude.

Answer:

D. The star's shape
