The mass of a star influences its luminosity, temperature, size, and evolution rate. Because the mass of stars in the same general area is the same, they will all evolve at the same rate. florist sherrills ford nc

WebAstronomers today still use constellations to name stars and meteor showers. There are a few different definitions of constellations, but many people think of constellations as a group of stars. Often, it's a group of stars that looks like a particular shape in the sky and has been given a name. These stars are far away from Earth. Star clusters are large groups of stars held together by self-gravitation. Two main types of star clusters can be distinguished: globular clusters are tight groups of ten thousand to millions of old stars which are gravitationally bound, while open clusters are more loosely clustered groups of stars, generally containing fewer than a few hundred members, and are often very young.

WebNuclear fusion releases energy, which heats the star and prevents it from further collapsing under the force of gravity. Astronomers call stars that are stably undergoing nuclear fusion of hydrogen into helium main sequence stars. This is the longest phase of a star’s life.

WebOftentimes, many stars are born from the same nebula, and remain close together in a star cluster.
