What is the closet star to earth?

Answer 1

Technically speaking, the sun is the closest star to Earth.

.

The next closest known star to the Earth is Proxima Centauri, red dwarf star

approximately 4.2 light years from Earth ... only about 278,000 times as far

from us as the Sun is. See the related link below for further information about

Proxima Centauri.

.

The next two closest known stars comprise the binary star system called Alpha

Centauri. Alpha Centauri is 4.4 light years from Earth.

.

It is postulated that another star, a red or brown dwarf star, closer to the Earth

than Proxima Centauri, orbits the sun in a highly elliptical orbit. This possible

star is code named Nemesis. See the related link below for further information

about a companion star.
That would be the Sun, an average everyday star. The next closest star to earth is Alpha Centauri, which is only four light-years away.

Answer 2

The Sun is a star. It's 93 milion miles from Earth. Aside from that, the stars in the Alpha Centari system lie roughly 4 light years from Earth. These are the closest stars other than our own Sun. It is also believed that the Sun may have a counterpart approximately 1 light year from us. If this is true, this star (now nicknamed "Nemisis") would have to be a Red Dwarf.

Answer 3

The nearest star to the Sun that we know of is Proxima Centauri, believed to be part of the Alpha Centauri system. If it is part of that system, it has an orbit around the system's barycenter of about 550,000 years, and is currently in that part of its orbit which puts it closer to the Sun than the barycenter.

It's just barely possible that a very small, very dim, very low mass star might be closer than Proxima, but recent surveys have all but ruled out any unknown red or brown dwarfs within about 10 light years.

Answer 4

-- The nearest one averages roughly 149.7 million kilometers. That's the one called the "Sun".

-- The next nearest one is in the constellation Centaurus. It's about 39,735,000 million kilometers.

Answer 5

The closest star to our solar system is proxima centauri at about 4.2 light years away.

Well the closest star to my solar system is Alpha Centauri. It is the closest star system to the Solar System, being only 1.34 parsecs, or 4.37 light years away from our Sun or 5,878,625,373,183.61 miles away

Answer 6

The closest star to earth is the sun. The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).

Answer 7

Strictly speaking, the CLOSEST star to the Earth is our own Sun. The next closest after that is Proxima Centauri, a tiny red dwarf 4.2 light years away. Even though it is the closest star to the Sun, it cannot be seen by the naked eye, because it is too dim!
The sun. It's a medium-sized star.
Technically the sun is the star closest to the Earth, but because we experience it so differently from the other stars, we do not normally think of it as such. The closest star to us aside from the sun is Proxima, a small star that is part of the Alpha Centauri star system. On average, Proxima is 4.22 light years away while the star system as a whole is 4.27 light years away.
The Sun is technically the closest star to the Earth. Besides that though, the star Alpha Centauri is closest. It is approximately 4.37 light years away
The star closest to earth is the sun, averaging 93 million miles over the course of

one full year.

After the sun, the next nearest star is Proxima Centauri, roughly 270 thousand times

farther from us than the sun is.

Answer 8

The closest star to Earth is the Sun. It is located approximately 93 million miles away from Earth.

Answer 9

The closest start on Earth is the Proxima Centauri. It is also the dimmest star from the Alpha Centauri or the Star System.

Answer 10

The closest star to earth is the sun. After that the closes is Proxima Centauri.
