It is called a white dwarf. It is the penultimate stage of a star the size of the Sun, which progresses with age from a yellow or orange star, to a red giant, to a white dwarf, and ultimately (after an immensely long period of time) a black dwarf. (There are no confirmed black dwarf stars because their formation may take much longer than the current age of the universe.)

What is is a cold dead star called?
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
What is the name of the star that is very dim and red in color?
The star that is very dim and red in color is known as a red dwarf. Red dwarfs are the most common type of star in the universe, characterized by their low temperatures and luminosity. An example of a well-known red dwarf is Proxima Centauri, which is the closest star to the Sun.
Why can't a lowest-mass star become giant?
A lowest-mass star, often referred to as a red dwarf, does not have enough mass to ignite helium fusion in its core, which is a crucial process for becoming a giant. Instead, red dwarfs can remain in the main sequence for billions of years, gradually burning hydrogen. When they exhaust their hydrogen, they typically cool and dim rather than expanding into a giant, as they lack the necessary core temperature and pressure for further fusion processes. Thus, they evolve differently from more massive stars that can become giants.
What star is very dim and a red color?
A very dim and red star is typically a red dwarf, which is the most common type of star in the universe. An example of a red dwarf is Proxima Centauri, the closest star to the Sun. These stars have a low luminosity and temperature, giving them a reddish appearance. Red dwarfs are often difficult to see with the naked eye due to their faintness.
9 stages of a star?
Stellar nebula: a cloud of gas and dust in space. Protostar: a young star still forming through gravitational collapse. Main-sequence star: stable fusion of hydrogen into helium in the star's core. Red giant: expansion of the star as it runs out of hydrogen fuel. Helium fusion: fusion of helium atoms in the core. Planetary nebula: outer layers of the star expelled into space. White dwarf: the core left behind after the outer layers are ejected. Black dwarf: a cooled and dim white dwarf. Supernova or black hole: the final stage, depending on the mass of the star.
What best describes giant star?
hot, bright stars
What is is a cold dead star called?
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
What is the dim star that forms from a collapsed red giant called?
It is called a white dwarf. It is the penultimate stage of a star the size of the Sun, which progresses with age from a yellow or orange star, to a red giant, to a white dwarf, and ultimately (after an immensely long period of time) a black dwarf. (There are no confirmed black dwarf stars because their formation may take much longer than the current age of the universe.)
What is a small dim star that is the leftover center of an old star?
a white dwarf
Is a red giant star farther away then a red dwarf star from earth?
Red dwarf stars may be the most common stars throughout the galaxy, and possibly the universe. They are so dim, however, that they are difficult to see.The red dwarf Proxima Centauri is the closest star to our Sun; however, it is not visible without a telescope. Doubtless there are a great number of stars further away that are entirely lost to view because they are so dim.If two stars have approximately equal apparent magnitudes, the dim & tiny red dwarf star is far closer than the enormous red giant.
What is the comparative and superlative forms of dim?
dimmer, dimmest
Does it make sense that a cool star should be dim?
no
What is the brightest star of capricornus?
The brightest star in the constellation Capricornus is Deneb Algedi, which is a binary star system located approximately 39 light-years away from Earth. It is a white giant star with a visual magnitude of about 2.8, making it the brightest star in Capricornus.
How does a stars temperature change as the star ages from main sequence star to a red giant and from a red giant to a white dwarf?
A regular stars temperature cools as it balloons into a red giant. The color shift is evident by the word red because red is the coolest color of heat. The surface of a dying star is cool because it is so much farther away from the core than when it is on the main sequence. After a star sheds its 'skin' the only thing that is left is the white hot core, which will eventually dim to a brown dwarf which is nothing but the cool charred remains of the white dwarf and will give off little to no light.
Does Saturn have a bright or dim light?
A supergiant star has an atmosphere that extends far from the star's center. On a surface area basis, square meters say, the surface is very dim. But since the size is so great the overall brightness is high. Betelgeuse is a good example. The outer atmosphere is so tenuous that there is actually a star orbiting within it. But it is so large that it shines brightly at the right shoulder of Orion.
Is the white dwarf the brightest star?
No; actually, white dwarves are rather dim.
A star that is very hot but dim is a?
That might be a white dwarf.
