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
Antares is the alpha star in Scorpius.
Antares or Alpha Scorpii is a red supergiant star of spectral type M1.5 Iab. It is about 65,000 times more luminous than our sun.
Betelgeuse, or Alpha Orionis, is a red supergiant and second brightest star in the constellation Orion.
All visible stars are within the the Milky Way Galaxy. Antares is no exception.
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.

Alpha Orionis
Betelgeuse (Alpha Orionis) is a red supergiant star.
Antares or Alpha Scorpii is a red supergiant star of spectral type M1.5 Iab. It is about 65,000 times more luminous than our sun.
Betelgeuse, or Alpha Orionis, is a red supergiant and second brightest star in the constellation Orion.
All visible stars are within the the Milky Way Galaxy. Antares is no exception.
Antares (Alpha Scorpii) is a huge red hypergiant star, with a radius 800 times that of our own sun. There are some bigger stars though, such as Betelgeuse (1180 solar radii) and V354 Cephei (1520 solar radii), but the biggest known star is VY Canis Majoris, which is estimated to have a diameter between 1800 and 2100 times that of our own sun. If it were in the centre of our solar system its edges would almost reach the orbit of Saturn.
