The Star That Always Stays
How Large Is a Star?
Stars vary in size from less than 8 per centum of the size of the sun to those with diameters of more than i,800 times that of the dominicus. In terms of mass, stars must have enough mass to support the nuclear chain reaction that takes identify in the core of a star, which is about 10 pct of the lord's day'due south mass. In that location is too a limit to how massive starts tin can grow, and scientists suspect that the limit is about 150 times the mass of the sun.
Scientists take only measured the size of two stars directly: the sun and a relatively shut and large star called Betelgeuse. All other stars are measured through the combination of observing their perceived brightness, distance and temperature. The sun'south diameter is about 864,000 miles, and it weighs more than 300,000 times the mass of the Earth. The sun is a fairly average-sized star. By comparison, Betelgeuse is about 700 times the size of the dominicus and much brighter.
Stars can change size as they historic period. For instance, the sun will increment to almost 300 times its current size when it becomes a cherry-red giant. Alternatively, when large stars collapse, they sometimes grade neutron stars. Some of the most dense items in the universe, neutron stars are but about 12 miles in bore, only a single teaspoon of neutron star material would weigh billions of tons.
