How long does the UY Scuti have left?

How long does the UY Scuti have left?

Stellar evolution models tell that UY Scuti has already left the main sequence and has started fusing helium in its core. This means it is left with just 10% of its life. Stars like these have a short lifespan of a few million years compared to trillions of years for red dwarfs.

Where was UY Scuti discovered?

UY Scuti was first catalogued in 1860 by German astronomers at the Bonn Observatory, who were completing a survey of stars for the Bonner Durchmusterung Stellar Catalogue. It was designated BD-12°5055, the 5,055th star between 12°S and 13°S counting from 0h right ascension.

What was the largest star ever discovered?

The star R136a1 was initially measured at around 250 to 320 times the mass of our own Sun. The new estimate places it between 150 and 230 times the mass of the Sun.

How old is the star UY Scuti?

The age of UY Scuti has not been calculated but it could be as young as few million years or as old as a few billion. In other words, we are uncertain to the age of the star. No ones lived as long as a star so no one knows for certain a stars age, its only a best guess estimation.

What old is the Sun?

What is bigger UY Scuti or 618?

Some would say the largest object in the universe is UY Scuti, the largest known star. It’s a red supergiant with a mass “only” 7–10 times the mass of the Sun, but with a radius up to 1,708 times the size! That’s only 0.3% the size of TON 618, but obviously still stupendously large.
