Betelgeuse: (A Mysterious Star) ,Facts You Should Know 2021
Betelgeuse is a red Supergiant mysterious Star which can be seen by our naked eyes in the night sky. Betelgeuse is Second Brightest Star (First one is Rigel) in the Orion Constellation and Tenth Brightest star in the Night Sky. If we see at near-infrared Wavelengths then Betelgeuse is the Brightest star in the Night Sky.
Suppose Betelgeuse is in the Center of Our Solar System. Can you predict what will happen? No ! Well, In this situation the Surface of Betelgeuse will be beyond the asteroid belt and It will orbit the mercury, Earth, Venus, Mars, and even Jupiter.
As per research and Calculation the mass of Betelgeuse is about 10-20 times that of Sun and its distance from the sun is calculated about 500-600 light-years. Because of the large mass the Betelgeuse is developing with a rapid speed and it is estimated that its life will end with a supernova explosion , which is most likely to occur within 100,000 to 200,000 years.
Quick Information :
|Mass||20 times the mass of Sun|
|Distance From Sun||500-600 Light Years|
|Diameter||700 million Miles|
|Luminosity||100,000 times that of sun|
During the main sequence life of a star, gravity causes hydrogen to fuse to form helium in the star’s core. However, when the hydrogen runs out and the helium accumulates, the game changes. Large stars like Betelgeuse will swell to a massive size, hence their supergiant status.
Meaning of Betelgeuse :
The meaning of Betelgeuse is , “The Shoulder of the Giant “
Size of the Betelgeuse:
Size: 617.1 million km
Betelgeuse is one of the largest known star and For Comparison It is approximately 950 times as large as Sun, If we take more Comparison then Just think that the diameter of orbit of Mars around the Sun is 328 times the Diameter of the Sun.
According to Infrared Studies from spacecraft have revealed that Betelgeuse is surrounded by immense shells. And also it is estimated that the largest of these shells has a radius of 7.5 light-years.
How old is Betelgeuse ?
Age : 10.01 million years.
As we know During the Life span of a star , Because of Gravity hydrogen Fuses to form helium in the Core of the stars. And when the hydrogen runs out of stock and helium freezes , then we see a change in the Star’s life.
A large and massive star like Betelgeuse will take shape to a massive size and then they become a Supergiant star.
The Stars which are in large shape burn their hydrogen in to helium very fast , that’s why they have a short life span. Let’s take a example to understand this , As we know the Betelgeuse star is at the end of its life and it is only 10 million years old, Whereas Our Sun is five billion years old and it is in its young age.
So we can Conclude that the large stars has a short lifespan as compared to a average size stars.
Betelgeuse Supernova :
In the year of 2019 , astronomers noticed that the brightness of the Betelgeuse star had decreased significantly. After this dimming everybody thought that, this is the last stage of Betelgeuse star.
But , on 22 February 2020, astronomers reported that Betelgeuse had stopped dimming and now may be it will will begin to brighten again.
So, we can say it is very difficult to predict the Supernova of this mysterious Star.
What will happen if Betelgeuse goes supernova ?
Have you ever thought what will happen when Betelgeuse star will explode ? Will it be harmful for Earth ? So, the answer is no. The Supernova of Betelgeuse star will not be harmful for Earth.
Though it will be not harmful but , when Betelgeuse will explode , It will shine as bright as the half moon in the night sky for more than three months.
And also we will be able to see the Supernova in the daytime. But the brightness of the Betelgeuse star would be concentrated into one point.
Betelgeuse Vs Sun : Betelgeuse compared to Sun
If we Compare our Sun with Betelgeuse star , then it is estimated that Betelgeuse is 950 times as large as our sun. And if we talk about their mass , then Betelgeuse star mass is 20 times the mass of Sun.
Constellation of the Betelgeuse :
The Betelgeuse star is in the Orion Constellation. The constellation Orion is one of the most beautiful patterns in the night sky, seen by naked eyes. Because of the giant Betelgeuse star Orion sometimes looks brighter and sometimes dim. This is because the giant red star Betelgeuse is present in the right Shoulder of the hunter. Hunter is the pattern made by Orion Constellation.
Orion Constellation :
In astronomy as well as in astrology Orion is most important Constellation. The name of the Orion Constellation is given after a “Mythological Hunter”.
Orion is one the most mysterious Constellation and it contains many bright Stars, Which are seen in night sky. One among these is Betelgeuse which is second most brightest star in the Orion Constellation .The Most Brightest Star in the Orion Constellation is the Rigel which is located in the Leg of the Hunter. And the Third brightest star in this constellation is Bellatrix.
Betelgeuse distance from Earth :
The distance of Betelgeuse Star From Earth is estimated to be 650 Light years approx.
Note : One Light Year is equal to 6 trillion miles
