Star Clusters
A star cluster is a group of stars that share a common origin and are gravitationally bound for some length of time. They are are particularly useful to astronomers as they provide a way to study and model stellar evolution and ages.

Star classification
There are different classifications of stars ranging from type O which are very large and bright, to M which is often just large enough to start ignition of the hydrogen.
A star
A star of spectral type A, white in color, with a spectrum dominated by the Balmer series of hydrogen. Lines of heavy elements, such as iron, are noticeable at the cooler end of the range.

STAR, the general term for the luminous bodies seen in the heavens; used also by analogy for star-shaped ornaments (see Medal; Orders and Decorations) or other objects, and figuratively for persons of conspicuous brilliance.
Star hopping involves "hopping" from star to star with your telescope, until you arrive at the location of the target object.
Star clusters are groups of stars which are close together in space, rather than just accidentally lined up one behind the other. There are several different kinds.
Star
A gravitationally bound ball of mostly hydrogen and helium gas which is self-luminous from internal nuclear fusion reactions. Stars can vary in composition and mass, with their radius and luminosity depending on mass and age.
Star maps show Aquarius as a young man pouring water from a jar, although Ovid, in his Fasti, says it is a mixture of water and nectar, the drink of the gods. The stream ends in the mouth of the Southern Fish, Piscis Austrinus. But who is Aquarius?

Locating stars and constellations on the celestial sphere is facilitated by a star map.
If the star's remaining mass is between 1 1/2 to 3 times the mass of the Sun, it will collapse into a small, dense neutron star (about ten miles in diameter, about 1.
The term star was originally associated with the visible stars we recognise from the night sky. Stellar means "star-like".
*Brown dwarfs are a type of failed star. They do not fuse hydrogen and so are technically not considered to be stars.
The best way of finding your way around the heavens is by using a star chart. At first these charts can seem a bit confusing but by picking out one or two of the more familiar constellations you can use these as pointers to other constellations.
Note: (var) means that the star varies in brightness.
Apparent magnitude: brightness, as seen from Earth; the lower the magnitude, the brighter the star. The Brightest Stars in the Sky ...

The star itself is Sirius. The brightest star in the sky, Sirius is also known as the "dog star". This is because it is in the constellation of Canis Major, or the Great Dog. It's name comes from Arabic, meaning "the scorched one".

We need to consider what the orbit of a distant binary star system looks like to folks on Earth.
Once a star such as our Sun has formed its heat will begin to affect the remaining gas disk. The temperature in the disk will be highest near the Sun and lower as one goes out. This is consistent with the trend (6) in composition for the planets.

Star Formation
Stars form from collapsing clouds of gas and dust. As the cloud collapses, its density and temperature increase. The temperature and density are highest at the center of the cloud, where a new star will eventually form.
