ExploraTour: A Peek into the Lives of the Stars

Explore the HR Diagram for yourself

Click on the individual stars to find out what they are like and where you can find them in the sky.

Look for supergiants and hypergiants at the top of the diagram, very small dwarf stars near the bottom and stars like our sun towards the middle.

You won't find neutron stars or black holes here at all. Why? They are so small, they would appear way below the bottom of the diagram.
