Is Stephenson in the Milky Way?

Is Stephenson in the Milky Way?

Stephenson 2 , also known as RSGC2 (Red Supergiant Cluster 2), is a young massive open cluster belonging to the Milky Way galaxy.

Is Stephenson 2-18 bigger than the solar system?

Size. 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.

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.

How far is Stephenson 2-18 from Earth?

Is Stephenson 2/18 located in the Milky Way?

It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a similar distance, although some sources consider it to be an unrelated or foreground red …

What is the closest universe in Milky Way?

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.

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.

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 WISE and Spitzer, it’s barely visible, as almost all of its energy is in shorter-wavelength light. The blown-off, ionized hydrogen, however, stands out spectacularly.

Which is the largest star in the universe?

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.

Is Stephenson 2/18 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 big is the Milky Way?

What is the smallest star ever discovered?

In 2017, an international team of astronomers announced the discovery of a so-called red dwarf star that’s so small it barely functions as a star. Code-named EBLM J0555-57Ab and lying some 600 light-years away, it’s similar in size to the planet Saturn.

What is the closest black hole to Earth?

Located just under 1,600 light-years away, the discovery suggests there might be a sizable population of dormant black holes in binary systems. The black hole Gaia BH1, seen in this artist’s concept near its Sun-like companion star, is the closest black hole to Earth discovered so far.

How many galaxies are there?

The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.

How big is the universe?

While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.

What is the nearest black hole to Milky Way?

As of February 2022, only one isolated black hole has been detected, OGLE-2011-BLG-0462, around 5,200 light-years away. For comparison, the nearest star to the Sun is about 4.24 light years away, and the Milky Way galaxy is approximately 105,000 light years in diameter.

Is there any satellite out of Milky Way?

The Milky Way has a number of satellite galaxies, but the biggest one is the Large Magellanic Cloud.

Did NASA find planets outside the Milky Way?

NASA said it has confirmed 5,005 exoplanets – or planets outside of our solar system. Most are in a very small region outside of our galaxy, the Milky Way. And by “small,” NASA means within thousands of light-years. One light year is 5.88 trillion miles.

Is Centaurus in the Milky Way?

It is the largest and brightest globular cluster in the Milky Way; at ten times the size of the next-largest cluster, it has a magnitude of 3.7.

Is UY Scuti in the Milky Way?

About UY Scuti The star lies near the center of the Milky Way, roughly 9,500 light-years away from Earth. Located within the constellation Scutum, UY Scuti is a hypergiant star.

Is UY Scuti in our galaxy?

But UY Scuti, located near the center of the Milky Way in the constellation Scutum, is around 1,700 times the Sun’s width.
