UY Scuti - The Largest Star Ever Discovered? [OOTW]

When considering star size, we are incredibly restricted with what we can't measure - the vast majority of the universe's stars lie outside of our galaxy, and are too far away to ever be measured. In spite of this, we have discovered some truly magnificent stars in our own backyard. Today, we will be looking at the biggest - UY Scuti. This magnificent titan of the cosmos is a staggering 2.3BN KM in diameter, and that is the least incredible of some of the numbers associated with it. Today, we will be analysing this star, and some of its close competition in the race for the largest star ever discovered.
