WebMar 20, 2024 · The Sun: The sun is considered to be an average star. It is the closest star to planet Earth and is trillions and trillions of kilograms in mass. While this may seem huge, … WebThe way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.
WebMar 22, 2024 · Our Sun is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of our solar system. The Sun is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet.

WebThey range in luminosity, color, and size – from a tenth to 200 times the Sun’s mass – and live for millions to billions of years. For stargazers Many main sequence stars can be seen with the unaided eye, such as Sirius – the brightest star in the night sky – in the northern constellation Canis Major.
WebNeutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. Matter is packed so tightly that a sugar-cube-sized amount of material would weigh more than 1 billion tons, about the same as Mount Everest!
WebMar 20, 2024 · White stars are formed when the stellar core of a star is exposed. White Dwarfs are interesting because the smaller diameter a white dwarf has, it has a higher mass. These stars eventually die as they are no longer producing energy to stay alive.
