Next up, the closest star to us.

That’s right, Sol our very own sun.  Like Terra for Earth, Sol is the Latin name of the Sun. That’s why we live in the Sol(ar) System.  The Sun is big compared to us, really big.  Actually, it is big compared to everything else in our system.  The Sun alone accounts for about 99.86% of all the mass in the neighborhood.  All the planets, asteroids and other cosmic visitors, like those comets, all together make up the other 0.14% of the Solar system.  Don’t you feel special now?

And, as you can see above, our sun is easily dwarfed by other stars in the Milkyway galaxy.  By the way, Antares isn’t the largest star we found that honor goes to:

Even bigger than that is all the space in between the stars and galaxies.  Technically, the Sun is is designated as a yellow dwarf star.  Sheesh, its enough to give you an inferiority complex!

But, it is our star and it is quite lovely.  All sorts of things happen on our sun that we are not even sure how or why.  Solar tsunamis, Solar quakes, coronal mass ejections, sun spots.

It is interesting to note that although they appear black, sun spots are in fact about 3000–4500 K (2727–4227 °C).  But, because the surrounding material is at about 5,780 K (5,510 °C) they look black.

This is what we think how the Sun is made and operates, but until we can develop the technology to actually withstand the pressure and the heat, we will not know.

Compared to the Sun, landing on Venus is a walk in the park!
