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: NoAntares: NoPolaris: YesBetelgeuse: Yes
Polaris is the closest of the three stars.
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.
Out of that list, 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.
No too sure what you mean by "main" stars but the most obvious ones are:- * The Sun * Polaris * Rigel * Betelgeuse * Sirius * Vega * VY Canis Majoris * Antares * Alpha Centauri * Barnard's Star
Polaris is hotter than Antares.
Every star is pretty huge, compared to anything in our life experience.In size.Betelgeuse: Red giant. Diameter 1,180 solar radii.Aldebaran: Orange giant: 45 solar radii.Alpha Centauri - Which one? A, B or C. For A, yellow dwarf: 1.22 solar radii.Polaris: Which one? A, Ab, B , C or D? For A, bright giant, 46 solar radii.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.
Betelgeuse.Polaris A has a radii of about 30 solar radii.Betelgeuse has a solar radii of about 1180.

No. The closest star to Earth is the sun. After that the closest star is Proxima Centauri. Polaris is several hundred light years away, which means a good number of stars are closer.
No, The north star is Polaris. Alpha Centauri is visible in the southern hemisphere skies.

Rigel, Sirius, Betelgeuse, Vega and Polaris
Southern Cross: Alpha Centauri and Beta CentauriPolaris: Alpha Ursae Majoris (Dubhe) and Beta Ursae Majoris (Merak).
No. Rigel is in Orion is is pretty far from Polaris.
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000
Alpha Centauri and Polaris are triple star systems.
Polaris by far. It has a diameter of 75 times the diameter of the Sun. Alpha Cen B has a diameter of 1.7 solar diameters.
The star you're looking for to tell direction is Polaris, the North Star. If you know what time it is, and have an accurate star map, you could use Betelgeuse to tell direction, but it's difficult.
Alpha Ursae Majoris (Dubhe) and Beta Ursae Majoris (Merak), which point to Polaris. (Northern Hemisphere)Alpha Centauri and Beta Centauri, which point to the Southern Cross. (Southern Hemisphere)
No. There are other stars nearer to it.
Our own star (the sun) has to be the most popular. The north Star (Polaris) is popular and useful due to its position - we can find north using it. Proxima Centauri is a very dim red dwarf star, but that is popular as it is the closest one to us after the sun, at a distance of 4.2 light years. Sirus is popular at it is the brightest (after our sun) and Betelgeuse also gets a lot of interest due to its size and reddish colour - it could explode any day now as a super nova.
