What is Canis Majoris?
The biggest known star is you Canis Majorris, a red hypergier measuring between 1800 and 2100 by sunlight. Its volume is almost a billion times the sun, although its density is much smaller. canis majoris means a large dog in Latin. If it was placed in the solar system, its surface would reach the Saturn orbit. Another way to say that is that you canis Majris is about 9 astronomical units (AUS) wide, nine times higher distance between the ground and the sun. There must be larger stars in other galaxies, but we currently lack binoculars strong enough to solve them. Hypertelescopy can help in this respect. It depicts a huge amount of material into the surrounding nebula, thanks to which the star is blocked in a visible spectrum. It must be observed in the infrared part of the spectrum. The deadly nebula can Canis Majoris is the width of ~ 4500 AU, about fifty times larger than stars and much larger than our solar system. There is a smaller circuit in the gas fogThe dust area, which has a temperature of 760 K and a width of approximately 260 AU. The star surface probably has a temperature of about 3650 hp, extremely cold for a star.
Unlike the main sequence stars, such as our Sun, you canis Mairis does not have a different photosphere, and so it just hitchhikes into space. Although he is the biggest known star, it is definitely not the smallest, partly because she has already released so many of her matter into the surrounding nebula.
Like all red giants and hypergiers, you canis Mairis is so great because it has exhausted all the hydrogen fuel in its core and began to connect the hydrogen to the shell outside the Helia core. In fact, you canis Majorris is so large that it can connect with helium, lithium, etc. to the periodic table for iron and on. Alternatively, it will have a core made mainly of iron, as well as planets. The problem with the post-shelter of fusion reactions is that they produce no energyI, and therefore cannot equalize the gravitational pressure generated by the star. When all the fusion fuel runs out, the star disastrous collapses in supernova explosion and becomes a black hole.
