At the core it’s 15 million. The core gives the sun enough energy to
give us all the light and heat we all need. The sun’s surface is
about 500 km thick. Sun spots are metallic fields that are cooler.

Earth only has one satellite. Earth was formed about 1.4 million
years ago. Life was formed about 1 billion years after. Estimates
on how much longer the planet will to be able to continue to
support life range for 500 million years, to as long as 2.3 billion
years.
