What kind of star is hot and has a very small radius?
north star
Why does luminosity of the star depend on both its radius and surface?
If the radius is larger, the surface will also be larger. As a functional dependency, you only need one - the radius, or the surface - whatever.
What star in Orion has the largest radius?
Saturn has the largest radius followed by Jupiter.The Equatorial radius of Saturn (not the rings) is about 60,268 kmThe Equatorial radius of Jupiter (not his rings) is about 71,492 kmso Jupiter is larger
Which is about the size of a city giant black hole white dwarf neutrons star?
Neutrons star is the same size of a city. This is 10 km radius.
What correctly describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
In what unit do I measure the radius of a star?
You can use kilometers. Or you can compare it to the radius of our Sun, and say, for example, "This star has 600 times the diameter [or radius] of our Sun."
Which star has a radius of 10 km?
That's the approximate radius of a neutron star, a.k.a. a pulsar.
Temperature and radius of merak star?
the distances of the merak star
What kind of star is hot and has a very small radius?
north star
What is the radius of the star Rigel?
Rigel has a radius of about 78 solar radii or 0.363 AU.
Why does the luminosity of the star depend on both its radius and its temperature?
The bigger the star's radius, the greater its surface area which emits the light. The bigger the temperature, the more luminous is the light the star is emitting.
What is the area of a star?
It's (4 pi) times (the star's radius)2.
How big is barnards star?
It has a radius of between 0.15 and 0.20 that of our Sun. The Sun has a radius of about 696,000 km, so Barnard's Star has a radius of between 104,400 km and 139,200. Average about 121,800 km
How wide is alnitak?
Alnitak is a multiple star: Alnitak Aa has a radius which is 20 time the sun's radius.
How much bigger is Pistol Star than the Sun?
Its radius is estimated to be about 300 times the radius of the Sun.
What is the radius of a red giant star?
A red giant can have a radius of 50 million to 500 million kilometres.
How can solar radii be used to describe the sizes of star including the subgroups of white dwarf giants and supergiants?
A star's radius is the distance from it centre to its visible surface. The bigger the star, the larger the radius. The radius is not the best means of comparing stars, it is perhaps better to compare stars by their mass.
