U is for UY Scuti

There are things that freak me out and UY Scuti is one of them.  It boggles my mind in such a way that it makes me want to curl up in a ball in a darkened room and consider just how insignificant we all are in this big old universe.

UY Scuti is a red super-giant star and currently the largest known by radius.  Approximately 1700 times that of our sun.  It has a volume 5 BILLION times that of our sun.

Seem big yet?  If it was at the centre of our universe it would engulf the orbit of Jupiter.  JUPITER!

Still struggling?  Take a look at the pictures below and try imagine it.  The universe is frigging amazing!

This shows UY Scuti compared to our Sun.


Follow the picture below, might give you a sense of just how big it is.
