VY Canis Majoris

VY Canis Majoris is a red HYPERGIANT star located in the constellation Canis Major, which is where it gets its name. It is the biggest star the astronomers have found yet. It is about 2100 solar radii, which means that it is as big as our Sun times 2100!

Now, let's do some math.

Diameter of the Sun is - 1.391.000 km (864.327 miles)

 => diameter of the VY Canis Majoris is -  1.391.000 x 2100 = 
2.921.100.000 km (1.815.087.390 miles)

That's big!!! And you don't even know what "BIG" is!

Sun comparing to planets in our system.

Now let's see how the Sun is realy small...

Reward task! Find the Sun! Hard one! Because of the VY Canis Majoris imaginary size!
