Every star is pretty huge, compared to anything in our life experience.
In size.
So a simple question can be so difficult. All are giants except Alpha Centauri, however, as this is a homework question, the teacher is obviously looking for Betelgeuse.
Of the stars listed, Alpha Centauri is the nearest star to Earth. But there is one closer; Proxima Centauri is a tiny, dim red dwarf star; "near" Alpha Centauri only by astronomical standards, it is still 3 light MONTHS away. But that's still 3 light months closer to the Sun.
From our corner of the galaxy, these stars are the most brilliant signposts in the heavens and can be enjoyed even from the light-polluted hearts of major cities.

In those list of stars, Alpha Centauri is the closest to the Earth. However, the Sun is the closest of all star to the Earth.
Alpha Centauri, although it appears to the naked eye as a single star, is a binary pair. Together they are designated Alpha Centauri AB, the more massive and luminous in the pair designated Alpha Centauri A, the less massive and luminous Alpha Centauri B. Together, this pair is the third brightest "star" in the night sky. There is a third star probably interacting gravitationally with the pair, Proxima Centauri, also designated Alpha Centauri C, a red dwarf which is not visible to the naked eye but is the next closest star to our Sun. Alpha Centauri B has about 90% of the mass of our Sun and is about 45% as bright. Note that Alpha Centauri B is not the "second" star (second brightest) in the constellation Centaurus: that is Beta Centauri, which is itself a trinary star system.
The Sun is "really" the closest star at 150,000,000 km (93,000,000 miles)Proxima Centauri is the closest star to us, at a distance of approximately 4.2 light years.(Proxima is Latin for "next to" or "nearest to")Alpha Centauri is the closest star system to us at a distance of approximately 4.3 light yearsThe Centauri system is a triple star system Centauri A and B have a mean separation of 11 AU's and are similar in size and temp to the Sun.Centauri C is a red dwarf it can not be seen with the unaided eye and was not discovered until 1918See related link for more information.
Alpha Centauri is not a single star but a multiple star system.The two main stars are Alpha Centauri A and Alpha Centauri B. These orbit each other fairly closely (closely enough that despite them being only a little over four-light years from Earth, they appear as a single star to the naked eye).Considerably further away from the two (but still close, by astronomical standards) is the star known as Proxima Centauri. It's believed to be gravitationally associated with (i.e. orbiting) the AB pair and is also known as Alpha Centauri C. Proxima is far enough from AB that, if it were bright enough to be seen with the naked eye, it would appear as a distinct star (in fact, it's a couple of degrees from AB; about four times the width of the full Moon).Because of its orbit (if it's in orbit, which we don't actually know for sure ... it might just happen by coincidence to be passing close by), Proxima is currently nearer to us than A and B are, hence the name.
Stars usually don't have "trails". If you see a "shooting star", that is not really a star, but a piece of dust that happens to fall into the atmosphere. It is also possible that you confuse this with pictures you saw of comets.
No. Approximately 6000 stars can be seen with the naked eye, but there are many trillions of star out there that we can NOT see with the naked eye. Even the closest star after the Sun - Proxima Centauri - can't be seen without telescopes.
Polaris is the closest of the three stars.
No. The sun is the closest star. The next closest star is Proxima Centauri
Proxima Centauri has an insignificant luminosity to Betelgeuse. Although it is the closest known star(4.2 light-years) to our Sun, it is virtually impossible to see because it is so dim. Betelgeuse, on the other hand, is a lot farther (640 light-years). Yet, it is one of the brightest stars in our night sky. This is because Betelgeuse has an extremely high luminosity.
No; in fact, the Alpha Centauri system is the closest star system to Earth.The closest star to us is the Sun; the next-closest star is Proxima Centauri, part of the Alpha Centauri system.
The Sun is the closest star. Next closest are the three stars of the Alpha Centauri system, of which the closest is Proxima Centauri.
Alpha Centauri
Alpha Centauri is the second-closest, at 4.5 Light Years away. The closest star is Proxima Centauri, which is 4.2 light years distant. However, Alpha Centauri is a star very much like our Sun, while Proxima Centauri is a very dim dwarf star, hardly visible from Earth even though it is closest.
Technically speaking the closest star to Earth is the sun which is about 93 000 000 miles (150 million kilometers) away. After that the next nearest star is Alpha Centauri and it is 4.37 light years away from our sun.
Proxima Centauri is the closest star to our sun-- but it's neighbor, Alpha Centauri, is nearly the same distance.
As the closest star to our sun, Proxima Centauri is in our galaxy.
ANSWER:With the Sun being the first, Proxima Centauri is the next closest at 4.22 light years away in the Alpha Centauri star system. See the related link for more information.
The Alpha Centauri system is about 4.2 light years away. The closest star is actually Proxima Centauri.
