Which star would you expect to be LEAST luminous?A. A star that is close and not very massiveB. A star that is far and not very massiveC. A star that is close and massiveD. A star that is far and massive

Respuesta :

The greater the mass of a star, the greater its luminosity.

Also, if the star is close, its apparent luminosity will be greater.

Therefore the start that is expected to be the least luminous is a star with smaller mass and far away.

So the correct option is B.
