Astronomers divide stars into five main groups according to their size.They are grouped according to their life span.
1.SupergiantsThey are the largest stars.
Examples are Antares and Betelgeuse.
Antares has a diameter that is 330 times
than the sun. Betelgeuse has a diameter
of 375 to 595 times that of the sun.
2.GiantsThey have diameters that are about 10
to 100 times larger than the sun's. Aldebaran
has a diameter that is 36 times that of the sun.
3. Medium-sized starsThey are as big as the sun. Other stars
in this group are Altair,Sirius,and Rigel.
4.White dwarfsThey are the small stars. The smallest
dwarf is Van Maanin's star. It has a diameter
of 8 370 km,less than the distance across Asia.
5.Neutron StarThey are the tiniest stars. Their mass
is less than that of the sun but are so compact.
Their diameter is about 20 km.

What term is given to a pair of stars that can determine are orbiting each other only by measuring their periodic Doppler shifts?
A pair of stars orbiting around each other are called binary stars.
What are the ways in which stars are differ in one another?
Principally by size. Larger stars are hotter and brighter. Next by age. As stars get older, they begin to run out of hydrogen fuel, start using helium and swell to red giants. Lastly by composition. Stars that formed earlier tend to have less carbon, oxgyen and "metals" in them.
Are all stars in a constellation near each other?
no stars are not close together in a contellestion
What is a triple star?
A triple star system is a system of three stars that are gravitationally bound to each other and orbit around a common center of mass. Triple stars can either be hierarchical, where two stars are closer to each other and the third is more distant, or trinary, where all three stars are relatively close to each other. Triple stars are relatively rare compared to binary stars.
What are the 3 ways in which stars may differ from each other?

How do binary stars differ form the supernovas and novas?

How do blue stars differ from the red stars?
Blue stars are hot, and red stars are cold. You'd think it would be the other way around, but weirdly enough, it's not.
What are two stars that go around each other?
Binary stars.
