It is located in the constellation Scutum and has a diameter of approximately 2.4 billion kilometers. UY Scuti’s size is due to its massive core, rapid expansion, and short lifespan. By studying stars like UY Scuti, astronomers can learn about the properties and behavior of these massive objects and gain a better understanding of the universe as a whole. UY Scuti was discovered back in 1860 by German astronomers at the Bonn Observatory. At that time, advancements in telescopic technology allowed astronomers to explore and catalog celestial objects with increasing precision.
