Which star is cooler and more brighter than the sun?
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
What is Bigger a Hyper Giant Star or Super Giant Star?
Hypergiants are super luminous supergiants. It isn't all about sheer size. Eta Carinae is a hypergiant but it is smaller than the supergiant Antares. This is due to the fact that Eta Carinae is about 60 times as luminous as Antares and 10 times as massive. Although size doesn't matter, the largest star VY Canis Majoris is a Hypergiant.
Is a red giant star larger then the sun?
Yes because the Sun is not a giant so all giants are bigger than the Sun.
What super is a star that is millions of times brighter than the sun?
Brightness is defined as the luminousity as seen from Earth. So the brightest star is the Sun.HD 93129A is a blue supergiant and one of the most luminous stars in the Milky Way and is 5,500,000 times more luminous than the Sun.
What is the difference between a red supergiant and a red giant?
A red supergiant is the largest type of star by volume, but not by mass. It is also one of the"coolest" active stars. These stars have fused most of their hydrogen to helium, and pressure from its core have swelled its size, to between 200 and 800 times the diameter of our Sun. Since the mass has not increased with the volume, the star's average density is comparatively low.
Star that is larger than the sun?
any giant or supergiant
What is the difference between a giant star and a supergiants?
A supergiant simply is a large giant - so, it is larger (in diameter) than a "regular" giant star.
Explain how a red star can be more luminous than a bluish-white star?
By being far larger - a red giant/supergiant.
Who is the bigger the big giant star or the sun?
A giant star is smaller than the sun.
Is a supernova a super giant?
A supernova may have been a supergiant star at one time, but it did not have to be. Any star with a mass greater than 3 times our sun will supernova. There are millions of stars having masses between 3 solar masses and supergiant mass for every single supergiant star... and every one will supernova when it dies.
Is it true that the sun is classified as a supergiant star?
No. The sun is a main sequence star far smaller than any supergiant.
Will a super red giant live longer than a red giant star and which will burn hotter?
A supergiant is brighter than a red giant. That means it spends its energy faster, and lives less. To burn its energy faster, it must be hotter in its nucleus. That doesn't necessarily mean that its surface temperature is faster (rather, it will usually be bigger, and have a larger surface to irradiate).
Which star is cooler and more brighter than the sun?
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
How big is a red giant?
A red giant will be about 10 to a 100 times bigger than our Sun. However that is just a red giant. A red supergiant will be about 100 to 1,500 times bigger than the Sun, whereas a red hypergiant will be anything greater that 1,500 times that of the Sun - Like VY Canis Majoris.
What is Bigger a Hyper Giant Star or Super Giant Star?
Hypergiants are super luminous supergiants. It isn't all about sheer size. Eta Carinae is a hypergiant but it is smaller than the supergiant Antares. This is due to the fact that Eta Carinae is about 60 times as luminous as Antares and 10 times as massive. Although size doesn't matter, the largest star VY Canis Majoris is a Hypergiant.
What is a bright giant?
A bright giant is a class of star that don't quite make it into the supergiant class but are much more luminous than giants.Eg. Epsilon Canis Majoris (Adhara): a blue-white (B-type) bright giant
Why do you call the sun a dwarf star?
Despite being larger than most stars, the sun is called a yellow dwarf because it is far smaller than the giant and supergiant stars.
