Our Sun

The Sun. It's the the star that brings us light and warmth. It sits there, 92,960,000 miles away from us, allowing us to see and not freeze to death.

Our sun is a low mass Spectral type G2V star in its main sequence, about halfway through its life cycle. It was born pretty much like every other star. It developed like any other star. The sun will eventually die, as everything does, but before that, it’ll use up all its Hydrogen fuel and fade away. Nothing too spectacular. It won’t explode or turn into a Black Hole, just fade away into a white dwarf. LIfe on Earth by this time will most likely be dead, so you really don’t have anything to worry about.

The age of the sun is about 5 billion years old. (Give or take ½ a billion years.)
The Sun got its name from the Ancient Romans. The Ancient Romans named our sun Sol, meaning sunlight or light. An apt name for something that bathes the Earth in light.

Fun Facts Page 1:
The Sun is ~100 times the diameter of Earth.

Fun Fact Page 2:
The Sun is ~5,000+ degrees Celsius at it’s surface, and 15 million degrees Celsius in the core.

Fun Facts Page 3:
The sun is composed of ~91.2% Hydrogen and ~8.7% Helium
The sun is not a solid, obviously. It’s not a liquid and it’s also not a Gas. What it is is Plasma. For those of you who don’t know what plasma is, it’s a soup of charged particles.

In Conclusion, the Sun is important to the Big History story because it exists. Without it, there’d be no Humans and no Solar System. Without humans, this course wouldn’t exist, unless there’s aliens on a planet that we don’t know about studying Big History.
