How many Earths can you fit in UY Scuti?
How many Earths can you fit in UY Scuti?
The largest star ever discovered is UY Scuti, which boasts a diameter 1,708 times that of the Sun. This massive size means that UY Scuti could hold the volume of 6 quadrillion 489 trillion Earths.
What if UY Scuti hit Earth?
So the force of 100 stars exploding would obliterate everything nearby. Even if Earth was far enough away to survive the blast, without the star, there would be no heat and no light, and life could not survive on Earth without them.
How much larger is UY Scuti than Earth?
It has an estimated radius of 1,708 solar radii (1.188×109 kilometres; 7.94 astronomical units), thus a volume nearly 5 billion times that of the Sun. It is approximately 2.9 kiloparsecs (9,500 light-years) from Earth….UY Scuti.

What if the Sun was replaced by UY Scuti?
If UY Scuti replaced the sun in the center of the solar system, its photosphere would extend just beyond the orbit of Jupiter. The nebula of gas ejected from the star extends far beyond the orbit of Pluto, to 400 times the distance between the Earth and the sun.
What is bigger than galaxy?
Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest structures known to date.
What is the hottest star in the universe?
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K. In this infrared composite from … [+] The blown-off, ionized hydrogen, however, stands out spectacularly.
What is the largest star ever found?
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.
Which star is bigger than Sun?
Mu Cephi – about 1500 times the size of our sun. Betelgeuse – about 900 times the size of our sun. Antares – about 530 times the size of our sun. Deneb – about 145 times the size of our sun.

What is the closest star to Earth?
Distance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away.
Why do stars twinkle?
The stars seem to twinkle in the night sky due to the effects of the Earth’s atmosphere. When starlight enters the atmosphere, it is affected by winds in the atmosphere and areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.
What old is the Sun?
How hot is the Sun?
What is the next star to go supernova?
The nearest stars likely to go supernova within the next few million years are Betelgeuse and Antares. Both are over 400 light years away, far more than the 30 light years at which the explosion could become dangerous. Another VERY massive star, Eta Carinae, visible in the southern hemisphere, could go even sooner.
How many galaxies are there?
If we made the most straightforward estimate using today’s best technology, we’d state there are 170 billion galaxies in our Universe. But we know more than that, and our modern estimate is even grander: two trillion galaxies.
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.
Can UY Scuti have planets?
Currently, we do not know if there are planets orbiting around UY Scuti. Even if it has a habitable zone the radiations emitted by the enormous star will sterilize everything. It may have been possible for life to evolve around these hypothetical planets before the star grew to such sizes.
Which is bigger Betelgeuse or UY Scuti?
At ~1,000 times the size of the Sun, Betelgeuse is an impressive star to be sure, but it’s no match for UY Scuti, currently the largest star known with a diameter around 1,700 times that of the Sun.
How long does 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.
