First off, someone needs to explain what we're looking at. I'd also like someone to tell me the origin/history of the H-R diagram. Next, I need people to add information that hasn't been included. You'll need a better look at the diagram, so feel free to download the picture file to view it's details.

The first part of the picture is a diagram of what happens to a star over its lifetime.

Nice start! Can anyone check out Kendra's light output number for our sun and then give us an idea of what that means to the average person?

You can find how much light (luminosity) the sun gives off by multiplying the surface area (1.35 per square meter ) by the radius (150 million kilometers).

This explanation Maddi doesn't make sense to me.

Yes 3.846 × 1026 watts is the luminosity of the sun. The sun is a variable star and therefore the lighting will change, thus the heat, brightness, the light outside, and the weather, will change and affect the average person

Okay, this is the last one on the year! Someone give me an idea of the amount of energy we're talking about in terms I can understand. Watts? 3.846x10^26? How many bon fires is this equivalent to? Help me! Comments are closed.
