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 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.
Antares, a red supergiant star located in the constellation Scorpius, is approximately 550 light-years away from Earth. This distance translates to about 5.2 trillion kilometers (or roughly 3.2 trillion miles). As one of the brightest stars in the night sky, Antares is easily recognizable, but its vast distance emphasizes the immense scale of the universe.
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.
Antares has a spectral class of M1LB.
About 1.953125 x 1011 or 195,312,500,000 times.
Antares is a slow variable star. All stars are "thermal"

Polaris is the closest of the three stars.
Betelgeuse and Antares are both prominent red supergiant stars, but Betelgeuse is generally brighter than Antares. Betelgeuse has an apparent magnitude of about 0.42, while Antares has an apparent magnitude of around 1.0. This means that Betelgeuse appears brighter in the night sky compared to Antares. However, both stars are among the brightest in their respective constellations.
Both are red supergiants.
All visible stars are within the the Milky Way Galaxy. Antares is no exception.

There is lots of information available about the star named Antares. It can be found in libraries, or online. Antares is one of the largest stars that man has ever discovered.
Antares is the most important star in the Scorpius Constellation.
A binary system is a term referring to two objects (usually stars, but also planets, galaxies or asteroids) whose gravitational interaction causes them to orbit about a common centre of mass.Antares has a companion star (or binary star) called Antares B which is at a distance of approximately 550 AU from Antares A. (Neptune for comparison is only 30 AU from the Sun). This "companion" takes around 878 years to orbit Antares A.
The brightest star in the constellation Scorpius is Antares, also known as Alpha Scorpii. It is a red supergiant star and is one of the brightest stars in the sky.
Antares is under the head or "claws" of Scorpius - the first three stars that emerge from the sky. It is easily recognizable as it is very bright and gives off a reddish hue.
