14 Giant Facts About VY Canis Majoris (Largest Star Of Recent Time)

For us the Earth looks huge, but in fact it is only a tiny dot in the immensity of the universe. The most curious thing is that the Sun is not the biggest star in the universe. Next we’ll talk a little bit about VY Canis Majoris facts – one of the biggest stars that exist in the universe and you can kill your curiosity about them.

1 VY Canis Majoris Was Largest Known Star

VY Canis Majoris facts

VY Canis Majoris is one of the largest known stars in the universe and can also be called VY Cma. At present other stas have been discovered which may even more gigantic than VY Cma. These stars may include UY Scuti , WOH G64, RW Cephei, Westerlund and many more.

2 VY Canis Majoris Is More Than 2000 Times Greater Than The Sun

VY Canis Majoris facts

This gigantic star has 2.9 billion kilometers in diameter (somewhere around 1,800 to 2,100 times greater than the sun) and is located 5,000 light-years from Earth. It has a reddish glow.

3 Three Billion Earth Can Be Placed Inside VY Canis Majoris

We can measure the size of this star as nine times the distance from Earth to the Sun. Within the VY Canis Majoris almost three billion planets would be fitted having the size similar to Earth.

4 VY Canis Majoris Is Well Known Star Among The 70 Septilions Of Stars

The curious thing is that there may be stars larger than the VY Canis Majoris since it is known that there are at least 70 septilions of stars throughout the universe.

5 Exact Location Of VY Canis Majoris Lies Under The Constellation Of Canis Major

VY Canis Majoris facts

VY Canis Majoris is located in the constellation of Canis Major, in the Milky Way. The name of this constellation was given due to Greek mythology. This constellation represented the dog of Orion, the giant hunter.

6 What Happens If It Occupies The Current Position Of Our Solar System

If it occupied the center of the Solar System, instead of the Sun; it would exceed Saturn’s orbit, so that Mercury, Venus, Earth, Mars, Asteroid Belt, Jupiter and Saturn itself would be devoured by it.

7 It Can Host Up To The 1000 Million Sun Size Stars

VY Canis Majoris facts

The Sun can host a million of planet like Earth but the giant star VY Cma may contain 1000 million stars which are equal in size with Sun.

8 Little Time To Live In The Universe

It has been estimated that this star can become a supernova within about 3200 years.

9 This Star Has Contradiction For Its Brightness

VY Canis Majoris facts

Through the Hubble Space Telescope and the WM Keula Observatory in Hawaii, have studied their behavior, estimating their radius between 1800 and 2100 solar radii.

Through the Hubble Space Telescope and the WM Keula Observatory in Hawaii, have studied their behavior, estimating their radius between 1800 and 2100 solar radii.

There are two controversial opinions on this topic concerning VY CMa. One of them (according to studies by Roberta M. Humphreys) the star is a very large and luminous red hypergiant.

The other (based on the studies of Massey, Levesque and Plez), is that the star is a normal supergiant, with a radius estimated at 600 solar radii.

In the first case, its surface would extend beyond the orbit of Saturn. Earlier estimates of its diameter have made it even larger, with a radius of 14 astronomical units, equivalent to 3000 solar radii.

It is necessary to take into account that it is not possible to observe the photosphere of VY Canis Majoris, and that what is actually observed is light reflected and re-emitted by the dust grains in the layers of material expelled by it, which makes it difficult this study.

It is likely that this star is on its way to becoming a supernova within about 3200 years. The distance from the earth to VY CMa is approximately 1.5 kiloparsec (or 5000 light-years).

10 It Is Also One Of The Brightest Infrared Objects & A Cold Star

VY Canis Majoris facts

VY Canis Majoris, one of the brightest infrared objects in the sky, is an old star about 5000 light-years away. It is half a million times brighter than the Sun, but it shines mostly in the infrared because it is a cold star.

11 It Has A Mass Equal To 25 Suns

It is truly “supergiant” – 25 times more massive than the Sun and so huge that it would fill the orbit of Jupiter, reaching almost to that of Saturn.

12 VY Canis Majoris Is Shedding Mass With A Great Speed

VY Canis Majoris facts

But the star is losing mass so quickly that in a million years – with an astronomical blink – it will disappear. The star has already shed a good part of its atmosphere, creating around it a layer containing dust and about twice of oxygen as much as carbon. It has been studied in detail by the Hubble Space Telescope.

13 Astronomy Community Still Increases Its Size

The star is a red supergiant, with a radius between 1800 and 2600 solar radii, although previous study estimates of its diameter have made it even larger, with a radius of 14 astronomical units, equivalent to 3000 solar radii.

Even so, VY Canis Majoris does not lose its red supergiant status.

14 Mystery: VY Canis Majoris May Have Identical Partner

For a time it was thought that this star would be a multiple star system (in fact, the star appears in several clouds of double and multiple stars), but although it has been found that the alleged companions are actually condensations in the aforementioned nebula and not real stars. Some authors consider that perhaps an authentic companion exists with a period of rotation around VY Canis Majoris of several thousands of years.
