Look up information about each star's mass and diameter, calculate the volume, and calculate mass / volume.
Or simply assume that the star with the smallest diameter has the largest density. This is usually the case, since the stars' mass varies way less than their volume.
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.
Betelgeuse is generally brighter than Antares. Betelgeuse is a red supergiant star in the constellation of Orion and is one of the brightest stars in the night sky, while Antares is a red supergiant in the constellation Scorpius and appears slightly dimmer than Betelgeuse from Earth's perspective.
The main star of Virgo is Spica, is the brightest star in the constellation Virgo, and the 15th brightest star in the nighttime sky. It is 260 light years distant from Earth.

Antares is an important star in the constellation of the Scorpion.
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.
polaris
It switches every 10,000 years with Spica as the North Star
Antares and Betelgeuse are supergiant stars, while Polaris is not. Alpha Centauri is a binary star system consisting of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.
NIcolus Copernicus did many observations on the spica but no one knows who discoveed the Spica Star
Antares is a red supergiant star and not a constellation or an asterism.
Spica is a binary star system located in the constellation Virgo. The primary star, Spica A, is a blue giant with a diameter of about 7.5 times that of the Sun, while the secondary star, Spica B, is a main-sequence star.
spica is hotter. even though btelgeuse is bigger it is not as hot as spica
YES, Spica is in Virgo.It is the brightest star in the constellation.
Antares is a slow variable star. All stars are "thermal"
spica
antares is one of the biggest star known.
Spica is the brightest star in the constellation Virgo.It has a spectral type of B1 and has a temperature of 22,400oK
