ExploraTour: A Peek into the Lives of the Stars
How Far Can You Turn up the Light?
How bright are stars? Some are barely as bright as our moon while others blaze forth with a million times more light than our own sun.
The Weight of It All
Stars can be found that weigh so little, more than a dozen would be needed to make up the sun's mass. But even these "little" stars are far heavier than the Earth. Some stars, called hypergiants, are heavier than 100 suns put together.
Getting to the Point ...
The add on the left tells you how big, bright, and large stars can be and their range of colors. Any star you find could respond to this add.
