A hypothetical object traveling at the speed of light would take about seven hours to travel around the great circle of UY Scuti, while it would take 14.5 seconds to go around the Sun. This ejection occurred at the time when mankind’s ancestors were learning to walk on two feet.
And as long as UY Scuti doesn’t eject too much mass in its remaining lifetime, it will eventually produce iron. And as long as UY Scuti doesn’t eject too much mass in its remaining lifetime, it will eventually start producing iron.
How many times bigger is UY Scuti than the sun?
UY Scuti is approximately 1700 times bigger than the Sun, with an amazing radius of 0.74 billion miles and around 10 times the mass of the Sun too. It is a red supergiant star, which makes it a little unusual.
This star belongs to a class of stars that varies in brightness because it varies in size, so it is likely that this number will also change over time. According to current models of stellar evolution, UY Scuti has begun to fuse helium and continues to fuse hydrogen in an envelope around the core.
Located in the Milky Way in the constellation Scutum, UY Scuti is 5,100 light-years away from us. Scientists believe that UY Scuti will evolve to higher temperatures and become a yellow hypergiant, a luminous blue variable or a Wolf-Rayet star.
The mass of UY Scuti is uncertain, mainly because it has no visible companion star by which its mass can be measured through gravitational interference. UY Scuti is the largest and most luminous of the three measured stars, with 1,708 ± 192 R☉ (1,188×109 ± 134,000,000 km; 7.94 ± 0.89 AU) based on an angular diameter of 5.48±0.10 mas and an assumed distance of 2.9±0.317 kiloparsecs (kpc) (about 9,500±1,030 light-years) that was originally derived in 1970 from modelling the spectrum of UY Sct.
As in the DC Universe, sometimes the clearest way for astronomers to express that something is really extraordinary is to add the prefix super. It has an estimated radius of 1,708 solar radii (1,188×109kilometers; 7.94 astronomical units), so a volume almost 5 billion times that of the Sun.
how many suns fit in uy scuti?
In the same space occupied by UY Scuti would fit about 6,520,000,000,000,000,000 or six quadrillion, five hundred and twenty trillion Earths. To give us an idea of its size, a plane travelling at the speed of light would take 14.5 seconds to go around the Sun, and the same object would take seven hours to go around UY Scuti.
In fact, there are as many as 30 stars whose radii fit within the smallest estimated size of UY Scuti, so it shouldn’t be too secure on its throne. VY Canis Majoris is thought to be 10 million years old and is expected to explode within the next 100,000 years.
You can see that the sun is represented in the center, but it is not even big enough to merit a visible spot. One of these extreme stars is UY Scuti, a red supergiant star and a beast that can fit 5 billion suns inside.
When the value is negative, the star and the Sun are getting closer to each other; likewise, a positive number means that two stars are moving away from each other. Although the name may be misleading, a light-year is the distance light travels in one year, or 63,241 Earth-Sun distances, or 9.5 trillion kilometers to be exact.
Scudder noted that the brightness of the star varies with its radius, with a margin of error of about 192 solar radii. If the number of Earths that can fit into UY Scuti is a bit too high to comprehend, perhaps the number of Suns that can fit into UY Scuti is easier to understand.
All stars, like planets, orbit around a central point; in the case of planets, it is the central star, like the Sun. Since the average distance between the Earth and the Sun is about 150 million kilometers, this count would be about 25 m away.
If UY Scuti were to replace the Sun at the centre of the solar system, its photosphere would extend a little beyond the orbit of Jupiter.
