What will happen when Stephenson 2-18 dies?

What will happen when Stephenson 2-18 dies?

As Stephenson 2-18 continues to burn elements in it’s core, it will die eventually, giving it’s mass back to the Galaxy. This mass will create new stars and planets.

How many Earths can fit into Stephenson 2-18?

Sun (our star) – About 1.3 million Earths can fit inside the sun. Stephenson 2-18 (the largest known Star) – About 8 million Suns can fit inside Stephenson 2-18.

What if Stephenson 2-18 replaced the sun?

Stephenson 2-18 has an estimated radius of 2,150 solar radii. If it replaced the Sun in our solar system, it would extend past the orbit of Saturn (1,940 – 2,169 R☉). The star’s size corresponds to a volume about 10 billion times greater than the Sun.

What is the hottest star in the universe?

The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.

Will the star explosion in 2022 destroy Earth?

What is the largest known star?

The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.

What is the biggest star in the Milky Way?

Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.

How big is the Milky Way?

What’s the biggest Sun in the universe?

Star name	Solar radii (Sun = 1)	Method

How long would we have to live if the Sun disappeared?

Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after. Within two months, the ocean’s surface would freeze over, but it would take another thousand years for our seas to freeze solid.

Will our Sun be converted to black hole?

Will the Sun become a black hole? No, it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.

Which is the biggest thing in universe?

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.

Is galaxy bigger than black hole?

And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller.

What is the closest galaxy to Earth?

The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.

How hot is a black hole?

Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.

How hot is a dying star?

Its surface temperature is a scorching 240,000 degrees Fahrenheit.

Is a star hotter than lava?

A red dwarf star, the coolest of the stars that can fuse hydrogen, sits at about 3000 C. Lava usually checks in at a temperature somewhere between 700 degrees and 1200 degrees. At its hottest, lava is only half the temperature of the surface of the dimmest stars.

Can Stephenson 2/18 be a black hole?

Stephenson 2-18 is a Red hypergiant Star that is in the constellation of Scutum within the Star cluster of Stephenson 2. It is 19,570 light-years away from the Earth, near the supermassive black hole named Sagittarius A*. It is the largest Star in the Galaxy.

How long would it take to orbit Earth Stephenson 2-18?

How big is Stephenson 2-18, among the largest stars in the known universe? It would take earth’s fastest jet over 500 years to travel around. It would take almost 9 hours at the speed of light. Its circumference equals the orbit of Saturn.

What did Stephenson do to Raptors?

Not only did Stephenson’s decision to head to the tin with time winding down incite an altercation on the floor, but it provoked Raptors swingman PJ Tucker to lash out at him after the game. “Tasteless. Classless. There’s nowhere in the league for that,” Tucker said, per Vigilant Sports’ Scott Agness.

How did Stephenson 2/18 get so big?

Stephenson 2-18 is a red supergiant. It would have started as a very massive main sequence star, and become a supergiant after the end of core hydrogen burning. During shell burning, stars expand as they blow off gases into the envelope. This expansion creates red giants.
