No, there is no dwarf star heading for Earth. The closest star to Earth is the Sun, which is a main-sequence star. Dwarf stars are common in the universe and many are much farther away from Earth.
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
About 0.5 AU, or about half the distance from Earth to the sun.
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.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
No. A white dwarf is the remnant of a low to medium mass star.
The Earth is currently headed away from the nearest dwarf star and won't start heading back towards it until about the beginning of July. However, there's no danger of a collision any time soon; we've been orbiting it like this for about five billion years. (The nearest dwarf star is, of course, the Sun.) There are other dwarf stars "headed towards" Earth in the sense that they're getting closer to us, but again, there's no danger of a collision in the foreseeable future; none of them are headed directly towards us, and the distances involved are so large compared to the relative speeds that the Earth will have become uninhabitable long before any of them could get here even if they were headed directly at us.
A white dwarf star is about the size of Earth.
No, a typical white dwarf star is roughly the size of the Earth.
Earth and the seven other planets of our solar system have a yellow dwarf star: the sun.
Black-headed Dwarf Chamaeleon was created in 1865.
Dwarf yellow-headed gecko was created in 1964.
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
The nearest star to the Earth is our Sun. The nearest OTHER star to our Sun is the red dwarf star Proxima Centauri, 4.2 light years away.
No. While a red dwarf star is quite dim compared to the sun. Viewed from up close, such a star would still be blindingly bright.
The nearest dwarf star is Proxima Centauri, about 4.24 light years away and so dim it can't be seen in binoculars.
Scientists believe that after our Sun's time is over or it blows up, it will become a dwarf star. A dwarf star is a star that is small yet has an astonishing amount of density. It is said that if even a quarter of an inch thick cube of any dwarf star were to be put on Earth, it would sink directly through the Earth and out the other side of Earth back into space where gravity practically does not exist.
