How Does The Sun Manage It?

[Mintaka]

If the earth was the size of a pea, the sun would be a large 1m diameter beach ball 118 metres away, so I have read.

 

I've tried to imagine this, and all I can think is - " How does a ball of fire that size manage to heat a pea sized sphere which is 118 metres away?"

It isn't a 'ball of fire'. Instead, it fuses hydrogen to create electromagnetic radiation (a great deal of it on the UV part of the spectrum), which hits the Earth, warming it. This radiation is very high-energy (especially the UV and gamma portions), so it transfers a lot of energy to the Earth.

Thank you.

Why have you got JoeK in your sig?

It's a nickname I have. Joe Klesczewski is rather long, so I shortened it Joe and my last initial (K). This forms Joe K., with a space between the Joe and the K.
