VY Canis Majoris (Example of Descriptive)



VY Canis Majoris or VY CMa is a red hypergiant star located in the constellation Canis Major or located in 4900 light years from Earth. It is the eight biggest star the astronomers have found yet in Milky Way.

Characteristic of VY Canis Majoris is has circle shape, and has dark orange color. Its volume is almost a billion times that of the Sun, though its density is much less. Since 1847, VY Canis Majoris is known as a red star. With surface temprerature about 3000 K, including cold temperatures for a star. VY Canis Majoris exhibits periodic light changes. Its period lasts for about 2,200 days. The age of VY Canis Majoris is 240 million light years. The Diameter of VY Canis Majoris is 2.921.100.000 km. While the diameter of the our sun is 1.391.000 km. If the earth is represented by a sphere having a diameter of 1 Centimeter the sun is equivalent to 109 centimeters in diameter ball. VY Canis Majoris and equivalent-sized balls approximately 2.3 kilometers. Imagine if the VY Canis Majoris is bigger than the Sun. So, how small we are in this world? VY Canis Majoris is arguably a dying star. Like the other big star, VY Canis Majoris became so big because hydrogen fuel has run out on it and finally become a black hole. And Imagine if the passenger airplane flying along the surface of this star at 900 km/h! It would take 1100 years to circle it one time. And if the light surrounding VY Canis Majoris light will take approximately 8 hours.
