Which is bigger a neutron star or a white dwarf?
A white dwarf is much larger than a neutron star.
Who is denser white dwarf or a planet?
A White Dwarf because the inside of a planet is denser than the outer layers of the planet combined. So the White Dwarf is smaller.
How dense is the white dwarf to your sun?
A white dwarf is several hundred billion times denser than the average density of the sun.
Is a white dwarf smaller than Pluto?
A white dwarf could be smaller or bigger than the moon since it's size varies depending on the mass of the white dwarf. Since the mass of the moon is 7.347 x 1022 kg and the mass of Pluto is 1.31×1022 kg the size of a white dwarf is also smaller or bigger than Pluto depending on it's mass.
Why no red dwarfs have become white dwarfs?
A red dwarf can last for a trillion years, or for several trillion years, before it runs out of energy (and turns into a white dwarf). That is much longer than the current age of the Universe. In other words, red dwarves didn't yet have time to become white dwarves.
What lives longer a dwarf hamser or a guinea pig?
Guinea Pigs live longer than Dwarf Hamsters.
What is the relationship between a black dwarf and a white dwarf?
A white dwarf will cool very slowly to become a black dwarf. This process will take longer than the current age of the universe.
Can a white dwarf stay a live for more than a thousand years?
Far more than that. It is estimated to take hundreds of trillions of years for a white dwarf to cool to a black dwarf.
Is a white dwarf older the a red dwarf?
Not necessarily. A white dwarf is simply the remains of a low to medium mass star that has died. A red dwarf is a low mass star. Since red dwarfs last longer than medium mass stars, one could easily be older than a white dwarf.
How long does it take for a white dwarf to become a black dwarf?
Billions of years - longer than the life of our universe has passed from now (21st century).
What is a star formed from a white dwarf that has lost its energy?
A white dwarf is the last stage of 97% of star evolution. A white dwarf will eventually cool down, and become a "black dwarf". Black dwarves are not expected to exist yet; to cool down to that level, it would take longer than the current age of the Universe.
Is betelgeuse hotter than a white dwarf?
No, the surface temperature of Betelgeuse is colder than the temperature of a white dwarf, the white dwarf is the hot core of a dead star. Also, red stars are always colder than white stars.
Which is bigger a neutron star or a white dwarf?
A white dwarf is much larger than a neutron star.
Is the sun larger than a white dwarf?
YES. A typical white dwarf star is only a bit bigger than the Earth.
Who is denser white dwarf or a planet?
A White Dwarf because the inside of a planet is denser than the outer layers of the planet combined. So the White Dwarf is smaller.
Is the moon smaller than a 1 solar mass white dwarf?
Yes. The white dwarf would be a bit bigger than the Earth.
How cold is a black dwarf?
A black dwarf is a hypothetical stellar remnant, created when a white dwarf becomes sufficiently cool to no longer emit significant heat or light.The crucial point is hypothetical, as the time required for a white dwarf to reach this state, is older than the Universe itself.Estimates place the temperature to be around 0.06 to 5 kelvin.
