Planets & Stars
... A star’s brightness depends on its size and how hot it is. Larger and hotter stars are brighter than smaller and cooler stars. Brighter stars send out more light energy. A dim star that is close to Earth can appear brighter than a more distant star that is actually very bright. ...
