VY Canis Majoris is a red supergiant star located in Canis Major constellation. This star is the biggest and brightest known to humankind.
Star was discovered in 1801 by french astronomer Jerome Laland. VY Canis Majoris is in our Milky Way, 4892 light years from Earth. Its radius is 1500 times bigger than Sun’s and it could fit inside million Earth planets. Furthermore, supergiant’s diameter reaches 2,4 million kilometers. If this star would replace the Sun, it would reach Saturn’s orbit. In addition, this star’s mass is bigger than the Sun’s only by 10-25 times. Its surface reaches 3200 °C while Sun’s surface 5600 °C. Star is brighter than Sun around 250 000- 500 000 times.
Supergiant star is very rare in our galaxy. To tell the truth, most stars in our galaxy are smaller than the Sun. Big stars burn their energy really fast and die after few million years. In comparison, smaller stars, like our Sun, counts their age in billion years.
Scientists calculated that VY Canis Majoris already burnt about half of its mass and that its age reaches around 10 million years. That leads to the conclusion that this star will blow up and become supernova in 100 000 years time. After star blows up it will probably form a black hole.
