A white dwarf who's progenitor star was about the same mass as our Sun will leave behind a stellar remnant around the size of our Earth.
Obviously if the progenitor star was larger or smaller, then the stellar remnant will also be larger or smaller.

∙ 7y agoA white dwarf has far more mass than any planet. Jupiter is the most massive planet in the solar system and so would be the "closest" in mass to a white dwarf, but it is still hundreds of times lass massive.

∙ 13y agoDifficult to know for sure. Brown dwarf stars are small and dim, and it's possible that there is one relatively close by that we've never noticed.
The nearest known brown dwarf star is Epsilon Indi Bb, one of two brown dwarf stars orbiting the star Epsilon Indi. It would not be detectable at all if it were not so close to the parent star, and it is possible that there are other solitary brown dwarf stars that are closer. Epsilon Indi is about 12 light-years away.
In fact, there have been suggestions that a brown dwarf star tentatively named "Nemesis" may be distantly orbiting the Sun, occasionally coming close enough to perturb clusters of comets from the Oort Cloud and dropping them into the inner solar system. Nothing like this has been discovered, however, and the idea has been generally discredited.

∙ 14y agowhite dwarf's are stars not just one white dwarfs are a completion of a star so it can be close or far

∙ 11y agoI'm pretty sure it is Sirius A. It is 8.6 light years (50,556,179,654,736 miles) away. It is also a binary system. It's sister star is Sirius B and it is a white dwarf.

How big is Eris compared to earth?
The dwarf planet Eris truly deserves its designation as "dwarf planet"; it is less than one quarter of Earth's diameter, and about one percent of Earth's mass.
What happens star's furnace stops?
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
What is the density of 1 solar mass white dwarf that has a radius of 10.10.10.10 km?
Re the radius, what units are the 10.4 in.(A white dwarf is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth).The density of matter in a white dwarf is, very roughly, 1,000,000 times greater than the average density of the Sun, or approximately 106 grams (1 tonne) per cubic centimeter.There is a limiting mass that no white dwarf can exceed called the Chandrasekhar limit, beyond which electron degeneracy pressure cannot support the object against collapse at which point it turns into a Type 1a supernova.
Compare similarities between white dwarfs and neutron stars?
A nova is created when additional material is accreted onto the hot surface of a white dwarf.If sufficient material is accreted that pushes the mass of the white dwarf over the Chandrasekhar limit of about 1.38 solar masses a type Ia supernova will occur.See related questions.
Why is the sun a dwarf star?
A yellow dwarf star, is a star on the main sequence that has a temperature range of between 5,200 to 6,000 Kelvin. It has a spectral class of G or possibly F.Our Sun is a yellow dwarf - much as you may not believe it, it is a dwarf compared to other stars!!See related question for a size comparison
Is a white dwarf bigger than a main sequence?
No. A white dwarf is the collapsed remnant of the core of a low to medium mass star. It has a mass comparable to that of a star, but is about the size of a small planet.
Are white dwarf stars a low mass star?
A white dwarf is the remnant of a low to medium mass star.
what star is smaller neutron star or white dwarf star?
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
Which planet is closest in mass to the size of planet Earth?
Venus
How is a dwarf planet like a planet?
it is exactly the same as a planet but its diameter and mass are not great enough to be considered a planet.
Is white dwarf a massive star?
No. A white dwarf is the remnant of a low to medium mass star.
Why would a white dwarf become a red dwarf?
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
How does the the mass and size of a white dwarf compare with the mass and size of the sun?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth.
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.
Which is the biggest dwarf planet?
Eris with a mass of 1.7×1022 kg.
The planet whose mass is closest to that of Earth's is?
Venus
What does a high mass and low mass star end as?
white dwarf
