Top 10 Largest Stars in the Universe | Universe's Top 10 Celestial Giants

Giant balls of hot gas, mostly hydrogen with traces of helium and other elements, make up stars.Astronomers estimate that the universe contains 200 billion–trillion observable stars.Hipparchus, the Greek astronomer, discovered stars and finished the first star catalogue in 129 BC.Johann Bayer was the first to name the star and the first to use the Greek letter in the star’s name.With a mass between 1000 and 10 million times that of the sun, stars form in a cloud of gas and dust that clumps together to produce a high density within the cloud. Gravity is strengthened when lumps collide with one another.
Have you ever wondered how many stars there are in the universe? Both scientists and philosophers have found this to be a fascinating question.

So here we present to you the top 10 largest stars in the universe.

 

 

 

Top 10 Largest Stars in the Universe:-

 

1. UY SCUTI

UY SCUTI

This red supergiant star, located in the constellation Scutum, has a diameter of 1476 million miles and is 1,708 times wider than the Sun. Approximately 9,500 light years from Earth, the star is located in the Milky Way galaxy’s centre.

NOMENCLATURE AND HISTORY

Was first catalogued by a German astronomer at Bombs Observatory. It was located North of Type Gamma Auto and northeast of Eagle Nebula. This star is slightly brighter and suggests that it was a new variable.

FEATURES

When parameters of scuti were measured in the summer of 2012 in the The Tacama desert of Chilli, Amber’s inferiority with a very large telescope led to the immediate conclusion that your Scooty is 100,000 more luminous and 1000 times bigger than the sun.

 

 

2. WOH G64

WOH G64

WOH G64 is a satellite galaxy of our own Milky Way galaxy, circling the Large Magellanic Cloud. G64, which is 1540 times larger than the sun, is covered in a thick layer of microscopic particles that reaches a diameter of a light year.
WOH G64 has a temperature of 3,100 degrees Celsius, making it another relatively cool star.

DISCOVERY

WOHG64 was discovered in 1970 by Bent wasteland, qalandar and Hedin at a distance of 50,000 away from the Earth. In 1986 infrared radiation showed the Super Giant surrounded by gases and dust which is observed at three-quarters of radiation.

Variability

WOHG64 exhibit brightness variation with primary period of 800 days and stars exhibit variation in visual wavelenght of six,other scientist discovered that brightness variability remains unclear.

PHYSICAL PROPERTIES

1.It get assigned spectrul M7.5 which is coolder than M5.
2.WOHG64 being categorized as exceeding brighter.
3. Star Low density, with High Radiating pressure and relatively opaque leads to fusion.

3. WOH 5170

WOH 5170

The Large Magellanic Cloud, is 1,461 times the size of our sun and it is to be the largest star in the galaxy, which situated in constellation Dorado.

 

4.RSGC1-F01

RSGC1-F01

This RSGC1-F1 cluster is located in the Scutum constellation and is thought to be approximately 14 million years old than another super giants.

 

 

5. HD 269551

Others Stars in Universe known for large metal like clouds and quiet known for 1439 times the size of the Sun.It is also unstable and expected to be the supernova explosion with next few million years.

LOCATIONS
The right ascension and declination of HD269551, which is equivalent to the longitude and latitude of Earth, indicate its location in the sky. It was travelling eastward at this time. According to studies conducted thus far along the earth’s equator, the right ascension expressed in time
Based on the coordinates, Dorando HD 269551 is situated in the southern celestial sky, which is comparable to the Earth’s hemisphere. The path of this star is the earth’s ecliptic, and it is located to the south of the eclipse. Where it revolves around the sun on its axis

FACTS

Primary Name:HD 269551
Spectral Type:OBe D
Emission Lines:Yes
Star Type: Emission-Line Star
Colour:blue – white
Galaxy:Milky Way
Constellation:Dorado
Celestial Hemisphere:Southern
Main Star: Yes

 

 

6. VY CANIS MAJORIS

Situated in the southern constellation Canis Majoris, VY Canis Majoris is an Oxygen star with a peak setting variable of 1.2 kilos per second. It is one of the biggest non-stars in the Milky Way galaxy, home to the most massive and luminous red supergiant.

HISTORY
founded in 1801, according to the seventh order of magnitude stars, by the French astronomer Jerome La Lands. Due to changes in emission or density, a star’s light diminished when viewed from Earth in 1850. However, by 1847, the star had been interpolated and was dubbed the Crimson star.

 

 

7. HD 12463

Annual shift of 3.4 to the south constellation of appu becomes visible from Earth,despite its ability observe apparent visual magnitude of 6.42.Star is located 956 light years away from the sun because of interstellar dust and have magnetic distance of 0.17.

 

 

8. CM VELORUM

In the constellation is CM Velorum. The red colour of CM velorum indicates that the star is currently the coldest in the universe. The temperature is lower than that of the sun, which has an effective temperature of 5777 Kelvin, ranging from 2400 to 3700 Kelvin.

LOCATIONS
Right ascension and declination are used to determine location. When the right ascension is positive—that is, it lies on the eastward sides—it is expressed in terms of time.
The declination, which is commonly expressed in degrees, is the object’s distance from the celestial equator, either north or south.

 

 

9. AH SCORPIO

A red supergiant variable star in the Scorpius constellation is called AH Scorpii.
Features
1. A red supergiant accompanied by dust that is categorized as a semi-regular variable star with a primary period of 714 days
A visual magnitude range of 6.5 is present.
3. There are no longer any discernible secondary periods.

 

10. HV 888

HV 888 inside the more expansive Magellanic Cloud. Its semi-regular classification suggests that it is a Supergiant.
Moreover, it is among the most extensively documented star types, with a range of 30,0000 to 50,0000 lakh times to the sun.

Therefore, one needs to rely on the top 10 largest stars to further their interest in the universe, as they contribute to a deeper understanding.
