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.
