You can fit 1 million earths inside the Sun. In fact, the sun accounts for more than 99% of the total mass of our Solar System.
It’s made up of 73% hydrogen and 25% helium, but those numbers are changing every second because at the sun’s core where temperatures are 27 million degrees Fahrenheit and with the strong gravity there, Hydrogen’s electrons are stripped from their protons, and they fuse together to turn into Helium.
Conversions like these are the source of the energy we get from the sun, and the light we see from the sun today, well it was created 100s of thousands of years ago when when modern humans started to exist.
At any given time, in the sun’s outer layer you have particles that have so much energy that they escape from the sun’s gravity, this is called the solar wind.
But sometimes you have bursts of radiation emitting from a sun spot, which are spots that are relatively darker and cooler due to magnetic fields. These are called solar flares. A very strong flare can actually take out all of the electronics on Earth.
