Stars form in large clouds of gas and dust called molecular clouds. Molecular clouds range from 1,000 to 10 million times the mass of the Sun and can span as much as hundreds of light-years. Molecular clouds are cold which causes gas to clump, creating high-density pockets. Some of these clumps can collide with each other or collect more matter ...

20 de mar. de 2019 · Stars spend 90 percent of their lives in their main sequence phase. Now around 4.6 billion years old, Earth’s sun is considered an average-size yellow dwarf star, and astronomers predict it will ...
A star is a luminous spheroid of plasma held together by self-gravity. The nearest star to Earth is the Sun.Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names.
26 de sept. de 2022 · Stars range in size from neutron stars, which can be only 12 miles (20 kilometers) wide, to supergiants roughly 1,000 times the diameter of the sun. The size of a star affects its brightness.
15 de jul. de 2014 · Types of Stars. Image credit: NASA. A star’s color relies on its temperature: hotter stars emit bluer light and cooler stars emit redder light. Temperature is also correlated to mass. Red dwarf stars have as little as 0.075 solar masses and a visible surface temperature less than 4,000 K. The most massive star known is R136a1, a Wolf-Rayet ...
