dwarf stars,giant stars,main sequence stars
No. Stars vary greatly in size and brightness.
By studying the Hertzsprung-Russel diagram we can learn a great deal about the sizes colors and temperatures of stars
stars come in a variety of colors. red, bright blue, yellow like our sun and even white. stars come in many different sizes too from 10 times the size of our sun to the size of a small island.
They have a different reyfractive index.
Stars come in different shapes, sizes, colors. This is due to the amount of spectra and temperature in each for classifying stars.Astronomers often use the Hertzsprung-Russell (H-R) Diagram plots stars color, temperature, luminosity, spectral type, and even evolutionary type.
like people, no 2 stars are absolutely identical so yes
because they are different sizes and different distances away from earth
It varies. Stars can be all different sizes!
No, stars come in many different sizes, masses and densities. Further, a star will change its size over its lifespan.
No.., the sun is a ball of gas, and stars are balls of gas.. so basically yeah - but but that means all stars are twins at different sizes.
No, not really. The Big Bang theory has to do with the universe as a whole, not piddly little things like stars.
because the sizes and the distances away from earth are different
Our own galaxy, the Milky Way consists of about 200 billion stars.
They are all three. That is why some stars are called White Dwarfs (they are relatively small) and Red Giants or even Supergiants. The Sun is a middle-sized star.
It can have many different sizes. Only the largest giants are no longer main sequence stars.
Hard to explain. Usually stars get bigger if they grow. Very large stars have shorter life. A very big star can end it's life as a super nova or a black hole.
