These stars are only 5–10 times the radius of the Sun ( R ☉), compared to red giants which are up to 100 R ☉. The coolest and least luminous stars referred to as blue giants are on the horizontal branch, intermediate-mass stars that have passed through a red giant phase and are now burning helium in their cores..
In this regard, is there a star bigger than the sun?
The size of our sun It turns out that our Sun is an average sized star. There are bigger stars, and there are smaller stars. We have found stars that are 100 times bigger in diameter than our sun.
Secondly, how do red giant and blue star compared to the sun? The large blue supergiant stars have up to 100 times the mass of the Sun, while small, red dwarf stars have less than one-tenth the mass of the Sun. (For comparison, the planet Jupiter has slightly less than one thousandth the mass of the Sun.)
Also Know, what is a blue star called?
Blue supergiant star. Blue supergiants are supergiant stars (class I) of spectral type O. They are extremely hot and bright, with surface temperatures of between 20,000 - 50,000 degrees Celsius. The best known example is Rigel, the brightest star in the constellation of Orion.
Are white dwarfs hotter than blue Giants?
Although the bluish-white star is hotter than the red star and thus emits more energy per unit surface area, if it is much smaller than the red star it may still emit less total energy in a given time. Rank the following in order of increasing luminosity: blue supergiant, the Sun, red giant, white dwarf.

What's the Most Massive Object in the Universe? A galaxy pileup of 14 merging galaxies known as SPT2349 is currently the biggest known object in the universe.Why do stars twinkle?
The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.What is the biggest galaxy?

How many suns are there in outer space?
For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone.What is Bluestar?
Bluestar is the common name for Bluestar Forensic, a more potent analog of luminol to detect traces of blood on crime scenes.What is a white star?
Stars like our sun fuse hydrogen in their cores into helium. White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel. Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.Will our Sun become a Blue Giant?
A purely theoretical group of stars could be formed when red dwarfs finally exhaust their core hydrogen trillions of years into the future. Although these stars can become hotter than the Sun they will never become more luminous, so are hardly blue giants as we see them today.What is a red star?
A red giant star is a dying star in the last stages of stellar evolution. In only a few billion years, our own sun will turn into a red giant star, expand and engulf the inner planets, possibly even Earth.What does a blue star symbolize?

A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently that it no longer emits significant heat or light.What is the blue sun?
Though the sun may appear yellow or reddish to the naked eye, it's actually an ordinary white star. And the blue version released by NASA was made using a specific wavelength of ultraviolet light known as CaK, which is emitted by ionized calcium in the sun's atmosphere.How big is a supergiant star?
Supergiant. Supergiants are the most massive stars. Supergiants can have masses from 10 to 70 solar masses and brightness from 30,000 up to hundreds of thousands times the solar luminosity. They vary greatly in radii, usually from 30 to 500, or even in excess of 1000 solar radii.Where are blue Giants located?
Blue supergiants (BSGs) are found towards the top left of the Hertzsprung–Russell diagram to the right of the main sequence. They are larger than the Sun but smaller than a red supergiant, with surface temperatures of 10,000–50,000 K and luminosities from about 10,000 to a million times that of the Sun.How many suns can fit in a red giant?

What is an example of a red giant star?
Examples of well-known stars in the RG phase are Aldebaran (Alpha Tauri) and Mira (Omicron Ceti). More massive Main Sequence stars evolve more quickly and expand further to become Red Super Giants (RSG). Betelgeuse (Alpha Orionis) is a well-known example of a RSG.
