Why are some stars brighter than others?
|
How bright a star appears to be depends not only on how bright it really is, but also on how far away it is. A dim star that is close to us can appear brighter than a more distant, brighter star.![Related Image](../../../images/qa2c01f12.jpg) | The Orion Nebula |
