M4 is about 75 light years across. M4 is easy to find in the sky, as it lies 1.

Along with NGC in the constellation Ara , which is also 7, light years away, Messier 4 is the closest globular cluster to our solar system. Messier 6 is an open cluster also known as the Butterly Cluster because its stars form a shape similar to that of a butterfly.

The cluster was discovered by the Italian astronomer Giovanni Batista Hodierna in and Charles Messier included it in his catalogue in The bright stars in M4 are mostly hot, blue, class B stars, but the brightest one is a class K orange giant, BM Scorpii.

The Butterfly Cluster has an apparent magnitude of 4. Ptolemy believed the cluster to be a nebula. The Ptolemy Cluster contains about 80 stars, the brightest of which has a visual magnitude of 5. M7 is approximately light years distant from the solar system.

It is roughly 25 light years in diameter. The age of the cluster is estimated to be around million years. Messier 80 is a globular cluster discovered by Charles Messier in M80 is about 95 light years in diameter and contains hundreds of thousands of stars. It is one of the most densely populated clusters in our galaxy. It lies halfway between the stars Antares and Acrab. It is visible in moderate-sized amateur telescopes. It is home to a significant number of blue stragglers, blue main sequence stars that appear to be much younger because they are bluer and more luminous than stars at the main sequence turn-off point for the cluster.

The progenitor star was T Scorpii. It is a vast star-forming region and one of the most active stellar nurseries containing some of the most massive stars known in the Milky Way. It is believed to contain tens of thousands of stars. Ptolemy described it as a nebula in AD. This open cluster has an apparent magnitude of 3.

Around 80 stars are part of this cluster, they have a combined mass of around times that of the Sun. This cluster is around million years old. Messier 4, also designated as NGC , is a globular cluster, the first one in which individual stars were resolved. It is located at around 7, light-years away from us, being the closest globular cluster to the Solar System. Messier 4 has a radius of around 35 light-years, and it is situated at around 1. Both objects are visible in wide-field telescopes.

Messier 4 is a loosely concentrated cluster of class IX and measures around 75 light-years across, and it is around Messier 80, also designated as NGC , is a globular cluster discovered by Charles Messier in It is located at around 32, light-years away. It is situated in a field of the Milky Way that is rich in nebulae, and it can be observed through modest telescopes. Messier 80 contains hundreds of stars, and it is among the more densely populated globular clusters in the Milky Way.

The brightest star in Scorpius is the red supergiant Antares, which has an apparent magnitude of 0. Currently, around 14 stars in Scorpius have been confirmed to host planets. Antares, designated as Alpha Scorpii, is the brightest star in the constellation of Scorpius, and usually the 15 th brightest star in the night sky.

This supergiant red star would reach the orbits of Mars and Jupiter if it were placed in our Solar System, instead of our Sun. Antares is the brightest, most massive, and most evolved star of the nearest OB association, the Scorpius-Centaurus Association. Antares is actually a binary star, with its two components being the red supergiant star Antares A, and a hot main-sequence star, Antares B. It is located at around light-years away from us, and it is cooler than our Sun.

Antares B, on the other hand, has temperatures of around 18, K, being more than three times hotter than our Sun. Shaula, designated as Lambda Scorpii, is the second-brightest star in the constellation of Scorpius, and the 24 th brightest star in the night sky.

The first-star system is designated as HR , and it has an apparent magnitude of 2. The secondary-star system is designated as HR , and it has an apparent magnitude of 4. These systems are located around light-years away from us.

All of these stars are several times hotter than our Sun. Dschubba, designated as Delta Scorpii, is a binary star located at around parsecs away from us, having a combined apparent magnitude of 2. Dschubba is a Gamma Cassiopeiae variable star.

This star is 4. Sargas, designated as Theta Scorpii, is a binary star located at around light-years away from us. It has an apparent magnitude of 1. Sargas is also the third brightest star in Scorpius. Epsilon Scorpii, also known as Larawag, is the fifth brightest star in Scorpius, located at around Girtab, designated as Kappa Scorpii, is a binary star located at around light-years away from us.

It has an apparent magnitude of 2. The primary star, Girtab A, is also a variable Beta Cephei star. Pi Scorpii, also known as Fang, is a triple star system located at around light-years away from Earth, having an apparent magnitude of 2.

The primary star A, forms an eclipsing binary event of the Beta Lyrae type. Both of its members are hot, B-type main-sequence stars that regularly eclipse each other. Jabbah, also designated as Nu Scorpii, is a multiple star system located at around light-years away from us.

The system is broken down into three groups, Nu Scorpii A, which has an apparent magnitude of 4. U Scorpii is a recurrent nova system in Scorpius, one of the 10 known recurrent novae in the Milky Way. It is the fastest nova with a period of around 10 years. U Scorpii is located near the northern edge of Scorpion, having a maximum apparent magnitude of 7. U Scorpii is situated at around 19, light-years. This star is quite young, being around 20 million years old.

The name is Latin for scorpion , or literally translated as the "creature with the burning sting. The Javanese people of Indonesia call this constellation Banyakangrem, meaning "the brooded swan" or Kalapa Doyong, meaning "leaning coconut tree. In Chinese mythology, the constellation was part of the Azure Dragon. In the Northern Hemisphere, Scorpius lies close to the southern horizon; in the Southern Hemisphere, it lies high in the sky near the center of the Milky Way.

Scorpius used to be larger. The ancient Greeks considered the Libra constellation to be the claws of the scorpion. Scorpius happens to be the location for several interesting exoplanets, who have metrics ranging from extreme old age to potential habitability. By comparison, the universe is about It's about twice Jupiter's mass and orbits around two stars, making it a circumbinary planet.

Gliese Cc is a "super-Earth" that is roughly four times as massive as Earth. It orbits a red dwarf called Gliese C; the star is part of a three-star system that is only 22 light-years away from Earth.
