the temperature of antares star is 3100 degreeC
yes it is hotter than the sun closest to us [earth]

Antares, a red supergiant star, has a surface temperature of approximately 3,500 degrees Celsius (about 6,300 degrees Fahrenheit). Its cooler temperature contributes to its distinctive reddish hue, making it one of the brightest and most recognizable stars in the night sky, particularly in the constellation Scorpius.
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.

Antares is a red supergiant star and not a constellation or an asterism.
(Alpha Scorpii) Antares (meaning "Rival of Mars") is the brightest star in Scorpius, one of the constellations in the zodiac. Antares is a M1.5Iab variable red supergiant star that is about 520 light-years from Earth and is about 230 times as big as the Sun. This incredibly massive, old, low-temperature (3500 K) star is the 15th brightest star in the sky; it has a visual (apparent) magnitude of +0.96 (var.) and an absolute magnitude of -5.2.

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.
The core temperature of Antares is estimated to be around 20 million degrees Celsius. This extreme heat is necessary for the nuclear fusion reactions that power the star and produce its energy.
