Well, honey, we usually determine the radius of a star by observing its luminosity and temperature, using a little something called the Stefan-Boltzmann law. In layman's terms, the brightness and color of a star give us a pretty good idea of just how big it really is. It's not rocket science... oh, wait, yes it is!

How many times larger is the sun than a star that has 0.1 solar radius?
The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.
What is the radius of the star Rigel?
Rigel has a radius of about 78 solar radii or 0.363 AU.
How much bigger is Pistol Star than the Sun?
Its radius is estimated to be about 300 times the radius of the Sun.
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.
What size is markab the star?
Alpha pegasi is the star which have traditional name Marko, comes from the Markab ( an Arabic word ) . This star is the third brightest star in the constellation Pegasus, and one of the four star in the asterism ( Great square of Pegasus ) .Radius of this star is 4.72 times more than solar radius
What is the radius of a G2III star?
The radius of a G2III star can vary, but on average it is around 10 times the radius of the Sun. This class of star is typically larger and brighter than the Sun, but smaller than supergiant stars.
How do you determine the radius if you only have the diameter?
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
What is the radius of a star?
The radius of a star is a measure of its size, typically expressed in units such as solar radii, where one solar radius is the radius of the Sun, approximately 696,340 kilometers (about 432,690 miles). The radius can vary widely among different types of stars, ranging from less than a third of the Sun's radius for small red dwarfs to more than 1,000 times the Sun's radius for massive supergiants. The radius is determined through methods such as observing the star's brightness, temperature, and spectral characteristics.
A star has a size is of 0.1 solar radius how many times larger is the sun than this star?
The Sun has a radius of about 1 solar radius. If a star has a size of 0.1 solar radius, this means the Sun is 10 times larger than that star. To find this, you simply divide the Sun's radius (1 solar radius) by the star's radius (0.1 solar radius). Thus, the Sun is 10 times larger in size compared to the star.
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.
How can one determine the radius of a corner?
To determine the radius of a corner, measure the distance from the corner to the point where two straight edges meet. This distance is the radius of the corner.

As the radius of a star increases how do you think it's luminosity might change?
As the radius of a star increases, its luminosity generally increases as well, following the Stefan-Boltzmann law. This law states that the luminosity of a star is proportional to the fourth power of its temperature and surface area. A larger radius typically means a greater surface area, allowing the star to emit more energy. However, the actual change in luminosity also depends on the star's temperature; a cooler, larger star may not be as luminous as a hotter, smaller one.
How many times larger is the sun than a star that has 0.1 solar radius?
The sun has a radius of approximately 696,340 kilometers, while a star with 0.1 solar radius would have a radius of 69,634 kilometers. To calculate how many times larger the sun is, we divide the sun's radius by the smaller star's radius: 696,340 km / 69,634 km = 10. Therefore, the sun is 10 times larger than a star with 0.1 solar radius.
What are the radius of a Polygon that is 500 sq ft?
Only cyclic polygons can have a radius and they are a tiny, tiny minority of very special types of polygons. For the vast majority of polygons, the concept of a radius makes no sense. Next, even if the polygon was assumed to be cyclic, there is not enough information provided by its area to determine the number of sides - which, in turn will determine its dimensions. For example, the polygon could be a long thin rectangle with a very large radius, or a near-square with a small radius.
What two properties of a star determine its luminosity?
The luminosity of a star is primarily determined by its temperature and size (or radius). A hotter star emits more energy than a cooler one, while a larger star has a greater surface area to emit light. The relationship between these properties is described by the Stefan-Boltzmann Law, which states that luminosity increases with the fourth power of the star's temperature and directly with the square of its radius. Together, these factors dictate the total energy output of the star.
