Antares is a red supergiant star located in the constellation Scorpius. Its size is quite impressive compared to our Sun. The estimated radius of Antares varies, but it is generally thought to be around 700 to 800 times the radius of the Sun. This immense size makes Antares one of the largest known stars. Keep in mind that the exact measurements can vary due to factors like observational techniques and uncertainties in stellar models.

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.
Antares is an important star in the constellation of the Scorpion.
The red supergiant star in Scorpio is called Antares. It is one of the brightest stars in the night sky and is located at the heart of the Scorpius constellation.
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.
Using the classification system of OBAFGKM for star color (from blue to white to orange-red), Antares is an "M".
Yes, Antares is larger than V382 Carinae. Antares is a red supergiant star, while V382 Carinae is a white hypergiant star. The size of a star is determined by its radius, and Antares has a larger radius compared to V382 Carinae.

Antares has a radius (not raduis) equivalent to approximately 883 solar radii.
Antares is a red supergiant star and not a constellation or an asterism.
Antares is a slow variable star. All stars are "thermal"

Sirius BSirius B has a radii of 0.0084 solar radii.Barnard's star has a radii of 0.196 solar radii.
Antares is red because it is a red supergiant star nearing the end of its life cycle. The red color is due to its cooler temperature compared to other stars, which emits light in the red spectrum. This cooler temperature causes the star to appear red in color when observed from Earth.
