Why are some stars different sizes?
But for all other stars, their sizes are determined by that simple balance: the force from the outward radiation, at the surface, has to equal the inward pull of gravitation. Larger radiation forces means the star swells to larger sizes, with the largest stars of all swelling to billions of kilometers.

What is a big star called?
Hypergiants — larger than supergiants and giants — are rare stars that shine very brightly. They lose much of their mass through fast-moving stellar winds. Related: Hypergiant star's weight loss secrets revealed.
Is a black hole a star?
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)

What size are blue stars?
Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.
Is every star the same size?
But stars are not all the same size. They range from the size of a city, to large enough to swallow half our Solar System! Neutron stars pack a lot of mass into a small volume. They may contain the mass of one or two Suns but are often just 20 to 40 km in diameter.
Why are some stars brighter and bigger than others?
The closer a star is to us, the brighter it will appear. Also, stars come in a variety of sizes and brightnesses. Larger stars usually shine more brightly than smaller stars do. So, how bright a star appears in the night sky depends on its size and how far away from us it is.

Who is the smallest star?

What is a yellow giant star?
A yellow supergiant (YSG) is a star, generally of spectral type F or G, having a supergiant luminosity class (e.g. Ia or Ib). They are stars that have evolved away from the main sequence, expanding and becoming more luminous. Yellow supergiants are smaller than red supergiants; naked eye examples include Polaris.
Are there red stars?
The color of a star comes from the temperature of its surface. The hottest stars are blue, cooler stars are white and yellow, and the coolest stars of all are red. Red stars come in one color, but many different shapes and sizes.

variable hypergiant The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.
How big is a yellow star?
Known as a "yellow hypergiant," The star is more than 1,300 times the diameter of the sun, much larger than scientists expected after earlier observations, European Southern Observatory officials said in a statement. You can see the yellow hypergiant in a new video from ESO as well.
Are all stars the same size?
But stars are not all the same size. They range from the size of a city, to large enough to swallow half our Solar System! Neutron stars pack a lot of mass into a small volume. They may contain the mass of one or two Suns but are often just 20 to 40 km in diameter.
Why do some stars appear larger?
A star's brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star – even though they are equally bright!
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
