What are clusters of stars called?
Star cluster, either of two general types of stellar assemblages held together by the mutual gravitational attraction of its members, which are physically related through common origin. The two types are open (formerly called galactic) clusters and globular clusters.
What do you call a group of stars in a constellation?
The patterns of stars seen in the sky are usually called constellations, although more acurately, a group of stars that forms a pattern in the sky is called an asterism. Astronomers use the term constellation to refer to an area of the sky.
What is the cluster of 7 stars called?
Pleiades star cluster
The Pleiades star cluster – also known as the Seven Sisters or M45 – is visible from virtually every part of the globe. It can be seen from as far north as the North Pole, and farther south than the southernmost tip of South America. It looks like a tiny misty dipper of stars.
What are large clusters of stars called?
A star cluster is a group of stars that share a common origin and are gravitationally bound for some length of time. The two basic categories of stellar clusters are open clusters, also known as galactic clusters, and globular clusters.
Why do clusters of stars form?
The simplest idea is stars form into clusters when a giant cloud of gas and dust condenses. The center of the cloud pulls in material from its surroundings until it becomes dense enough to trigger star formation. From this study, they discovered the stars on the outskirts of the clusters actually are the oldest.
What type of stars are the largest?
Supergiant Stars: The largest stars in the Universe are supergiant stars. These are monsters with dozens of times the mass of the Sun. Unlike a relatively stable star like the Sun, supergiants are consuming hydrogen fuel at an enormous rate and will consume all the fuel in their cores within just a few million years.
