About the star code name

As we had the new major version to be released we needed a new star name for it. So UY Scuti was chosen for Tiki 21!

UY Scuti is known as one of the biggest stars we know so far. It can be found in the Scutum constellation but it is not the brightest star on the night sky.

Wikipedia wrote:
UY Scuti (BD-12°5055) is a red supergiant in the constellation Scutum. It is one of the largest known stars by radius and is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56.
