Did this Early this morning. Something quick and easy plus a test.
UY Scuti is a red supergiant star that can be located in the constellation of Scutum. The star can not be seen by the naked eye, you need a telescope to see it.
UY Scuti is one of the largest giant stars in the milky way, to put it in context, if the centre of UY Scuti was where our Sun was, the star's radius would extend out to Jupiter or even as far as Saturn. The diameter is about 2.4 billion Km!!! Or about 1,710x bigger than our sun.
UY is a semi-regular variable star in that it expands and contracts on an irregular base. The star roughly pulsates about every 740 days.It will go supernova one day but even though it is a large star, it will not go supernova in the next million years because it has to work through the elements in its core until it gets to Iron. After Iron, it will not be able to continue to fuse elements any further
