What are the constellations you see in the southern hemisphere in summer?

In the southern hemisphere during summer, notable constellations include Orion, which is prominent due to its bright stars, and the Southern Cross (Crux), a distinctive feature of the southern sky. Other visible constellations include Scorpius, with its bright star Antares, and Centaurus, which contains Alpha Centauri, the closest star system to Earth. Additionally, the Large and Small Magellanic Clouds, irregular dwarf galaxies, can also be observed. These constellations are best viewed from December to February, the summer months in the southern hemisphere.


Which constellations can you see in the summer?

In the northern hemisphere the constellations on the meridian on June 21 have a right ascension of 18 hours, and constellations from 15 to 18 hours can be seen in summer evenings. They are not as bright as the winter constellations. The main ones are Boötes (main star Arcturus), Corona Borealis, Serpens Caput, Libra, Hercules and Ophiuchus. In the southern sky, Scorpio (main star Antares). In the summer the circumpolar constellations like Cassiopeia, Ursa Major, Perseus and Draco can be seen although not in their usual winter positions.


What is the temperature of the brightest star in scorpius?

(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.


How many stars does antares have?

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.
