Antares star (Summary and Facts)
(Antares, Antares A, Alpha scorpii are same star name)
*Antares star is a red supergiant star.
*It has 700✖ times the diameter of the sun.
*It is one of closest red supergiant to earth and approaching to its end within the upcoming million year. It will explode into a supernova.
(A big star burns their fuel much faster than a small star, and that's why our sun lives long than Antares)
(A big star burns their fuel much faster than a small star, and that's why our sun lives long than Antares)
*sun is denser than Antares. (Due to its ending life span)
*The luminosity of this star is higher than the sun.
*Antares(Anti-Ares) is a Greek word that means Anti-Mars. Greeks used this word because it looks similar to Mars in the night sky.
*Antares(Anti-Ares) is a Greek word that means Anti-Mars. Greeks used this word because it looks similar to Mars in the night sky.
*It is enough to enclose the orbit of Mars around the sun.
*It is in one of the famous constellations - Scorpio constellation. And It is considered to be the heart of Scorpio Constellation. Generally, It arises in the southern celestial hemisphere.
*It is about 604 light-years from Earth and 16th brightest star in the night sky.
*In the night sky, Antares may appear single with the naked eye, but it is the binary star (When two stars are orbiting a common point[Barycenter]). We can call the second star as Antares B. It is the hot main-sequence star and smaller(compare to Antares) in size.

*It appear all night on 31st May.
*Around 30 November to 2 December, It comes very near to the sun.
*Antares B is massive than our sun. (Approx 7✖ to 8✖ times).
*Antares B is hard to notice with a small telescope because of the glare of Antares.
*Antares B is a bluish star. In lunar occultation, the moon can be hiding Antares glare to the observer on Earth. In the way, a person can see Antares B with a small telescope.
*Planets may hide the glare of Antares. Example Venus But, gaps are huge.(last 550 B.c and next 23 century).
*Antares A and Antares B are also known as alpha Scorpii A and alpha Scorpii B, respectively.
*Brazil has 27 stars in his flag, which represents his 27 states. Antares represents the state of Piaui.
*Antares and Antares B have a radius of 885 solar radii and 4 solar radii. ( 1 solar radius = Sun radii = 696340 km)
*It has a mass of 12.4 solar masses. And Antares B has a mass of 10 solar masses. (1 solar mass = sun mass = 2 * 10^3 kg)
*Antares A and Antares B are separate with 550 astronomical units. And the orbital period is about 2550 years. (Astronomical unit = 149 million km = distance from the center of the earth to the center of the sun)
*In 2015, A team of astronomers found an exoplanet by four times the mass of Jupiter, orbiting the Antares and it takes 550 Earth years. ( 1 Earth orbit = 365 days)
*It is moving with a speed of 20.7 km/sec relative to the Sun in Milky-way.
*Ancient Chinese called supergaint as Fire star.
*It is in our milky-way. The distance between the Antares center to the galaxy center is about 22 thousand light-years.
*Antares and Antares B have a temperature of 3200 C and 18226 C, respectively. (Antares star is cooler than Antares B star because its lifespan is ending)
*Antares B has discovered by Johann Tobias Burg. (In April 13, 1819)
*It is only 12 million years old, but it’s near the end of his lifespan.
*It is the most massive, brightest and evolved stellar member of the nearest association, the scorpius centaurus association.
*It is seen on the left surrounded by a yellowish nebula of gas which it has itself expelled.
*Ancient Māori people of New Zealand called Antares as Rehua.
*Antares B is at an angular separation of 2.86 arcseconds from the sun.
*Betelgeuse is only slightly bigger than Antares.(Betelgeuse is 10th brightest stars of the night sky)
*The surface of Antares is cooler than the Sun and emit much of their energy in the infrared.
*In the central and southern U.S. can see the entire scorpion with ease, but in the northern states, the bottom of the tail scrapes along the southern horizon and may not be visible.
*It is also named as HR6134, HD148478, HIP80763.
*It pump out about 60000 times the energy of our sun.
*Arabic says Antares as Kalb al Akrab in their history. And it means the heart of the scorpion.
*It has covered a big surface than the sun. And therefore, light can escape easily, which makes them a brighter star.
*In India's history, Antares star had a name Kettai but wait, we have many languages, therefore, there were also many names.
*Brazil has 27 stars in his flag, which represents his 27 states. Antares represents the state of Piaui.
