We all know the Sun is massive.  The Sun’s mass is 1,989,100,000,000,000,000,000 billion kg. Which means it contains 98.86% of the mass in the Solar System. One million Earths could fit inside the Sun.


The beautiful symmetry of a total solar eclipse happens because purely ‘by chance’. The sun is 400 times larger than the moon, but is also 400 times farther from Earth, making the two bodies appear the exact same size in the sky.


And one day, the Sun will die. As it runs out of Hydrogen, it will begin to expand, before it dies. Expanding enough to engulf the planet. The planet will burn much earlier when the sun expands though.
Fun facts, huh?
