Explain how UY Scuti and J0523 are different.
UY Scuti and J0523 are limitlessly unique. The most apparent distinction is that J0523 is

the littlest known star and furthermore the littlest conceivable star while UY Scuti is the most
prominent star known. The previous is a diminutive red dwarf, while UY Scuti is a red
supergiant. The shade of a star demonstrates its temperature, where red shows a temperature
scope of 2,400– 3,700 K (or beneath 3,700 K, regardless). J0523 has a temperature of 2074 K,
though UY Scuti has a temperature of 3,365 K. The two stars are cool for various reasons. J0523
doesn't have a great deal of mass and is along these lines of lower temperature, while UY Scuti
has a significant considerable mass and would have been a ton hotter in its initial life, yet it's as
of now a developed star nearing in a late period of stellar advancement (nearing the finish of its
life). As UY Scuti is a red giant, it has depleted the supply of hydrogen in its centers and has
begun a nuclear combination of hydrogen in the shell encompassing the middle, and along these
lines, the external layers extend while the temperature of the shell drops. UY Scuti would have
been around 25 M☉ (up to 40 M☉) when it shaped and lost the more significant part of its mass.
UY Scuti has a lifetime of roughly 3– 80 million years. J0523 in the, on the other hand, will
proceed atomic combination for 4.61 trillion years.

How will this happen?
