Interesting facts about stars
• There are more double star systems in the known part of the Universe than single ones.
• The surface temperature of a star is many orders of magnitude lower than the temperature of its core.
• Brown dwarfs, or protostars, are the coldest of all stars. Jupiter, by the way, could well become a brown dwarf if it were a little more massive. Fortunately, it didn't work out.
• The larger the star, the shorter its life cycle. The longest, trillions of years, live red dwarfs. By the way, they are the most common type of stars in the Universe.
• In fact, all stars in the visual spectrum appear white, even our Sun. It appears yellow to us due to the fact that its rays are refracted by the atmosphere.
• The brightest star in the night sky is Sirius. By the way, it is also a binary star system.
• The most massive star known to us is the blue hypergiant R136a1.
• Its mass is 256 solar, and it emits light into space 10 million times more than our Sun.
• And for a long time VY Canis Majoris was considered the largest star known to mankind - the diameter of this red hypergiant is from 1300 to 1630 solar, that is, about two billion kilometers. If VY Canis Majoris were in place of the Sun, its surface would be between the orbits of Jupiter and Neptune. But later it was found that UY Shield is even larger - its diameter reaches 1708 solar.
• Some scientists believe that the red supergiant Betelgeuse has already exploded, turning into a supernova, and in the not too distant future, the light of this explosion will reach us.
