What are cool stars?

[¦kül ¦stär] (astrophysics) A low-temperature star, generally visible in the infrared range of the electromagnetic spectrum.

What kind of star is Sun?

yellow-dwarf main sequence star
Related news. Our Sun is categorized as a G-type yellow-dwarf main sequence star. It is predicted that our Sun will remain in the main sequence phase for a few billion more years. Stars can live for billions of years, but their lives can be shorter or longer depending on their size (technically, their mass).

How many group of stars are there?

A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. There are 88 “official” constellations.

What type of stars are bright and cool?

Cool, bright stars (upper right of the graph) are called giants (red and super), and the hot, dim stars on the bottom, left of the graph are called white dwarfs. Stars of medium to small mass, like the Sun, start as main sequence stars, become red giants, and then white dwarfs.
