The Virgo Cluster is a tiny cluster of galaxies in the constellation Virgo, with a center distance of 53.8 0.3 Mly (16.5 0.1 Mpc). The cluster is the heart of the larger Virgo Supercluster, of which the Local Group (which contains our Milky Way galaxy) is a part. It has around 1,300 (and maybe up to 2,000) member galaxies. The Virgocentric flow is how the Local Group perceives the mass of the Virgo Supercluster. The mass of the Virgo Cluster is estimated to be 1.2.

What is the Virgo Cluster made up of?
The cluster is made up of spiral and elliptical galaxies in a rather varied mix. The spiral galaxies of the cluster are thought to be dispersed in an oblong prolate filament, roughly four times as long as it is wide, spanning down the line of sight from the Milky Way as of 2004. Elliptical galaxies have a higher center density than spiral galaxies.
The cluster is made up of at least three subclumps: Virgo A, which is focused on M87, Virgo B, which is centered on M49, and Virgo C, which is centered on M60, as well as an LVC (Low Velocity Cloud) subclump, which is centered on the giant spiral galaxy NGC 4216. The Event Horizon Telescope Collaboration spotted the event horizon of a supermassive black hole in the large elliptical galaxy M87 in 2019.
The dominant subclump, Virgo A, is produced by a mixture of elliptical, lenticular, and (typically) gas-poor spiral galaxies, and has a mass of around 1014 M, which is roughly an order of magnitude greater than the other two.
What is the size of the Virgo Cluster?
The Virgo Supercluster (Virgo SC) or Local Supercluster (LSC or LS) is a mass concentration of galaxies that includes the Milky Way and Andromeda galaxies. Within its 33 megaparsec diameter, there are at least 100 galaxy groups and clusters (110 million light-years). The Virgo SC is part of the PiscesCetus Supercluster Complex, a galaxy filament, and is one of around 10 million superclusters in the observable universe.
According to a 2014 study, the Virgo Supercluster is just one lobe of Laniakea, a larger, rival referent of the term Local Supercluster centered on the Great Attractor.
In the Virgo Supercluster, how many planets are there?
It can be found in the direction of the constellation Virgo, as its name suggests. Virgo comprises 1,300 possibly even 2,000 constituents, compared to the hundreds of galaxies in the prior groups and clusters. They total 1.2 quadrillion solar masses, which are scattered out over 7.2 million light-years.
The Virgo Supercluster contains how many galaxies?
This is a collection of genuine photographs of the galaxies that make up our Local Supercluster. They’ve been shrunk down (albeit not to scale) and roughly positioned in relation to each other.
Clustering of galaxies appears to be the norm rather than the exception; roughly three-quarters of all galaxies are found in clusters. Many tiny clusters of galaxies, like as the Local Group, are seen in close proximity. The Virgo Cluster, a massive cluster of 2000 galaxies, approximately 65 million light years away. The Local Supercluster is named for the proximity of about 50 nearby tiny groups of galaxies to the Virgo cluster, which suggests that they all form one vast flattened cluster of clusters.
The Local Supercluster is frequently referred to as the Virgo Supercluster since it is centered around the Virgo Cluster of galaxies.
Its equatorial plane is nearly parallel to our own Galactic plane.
With a diameter of nearly 100 million light years, our Supercluster has a combined mass of about 1015 times that of the Sun.
The Local Group, which is located on one of the Local Supercluster’s edges, appears to be rotating around its core at a rate of about 400 kilometers per second.
Is the Virgo Cluster visible?
The stars of the Big Dipper can be used to find Arcturus and Spica. The arc of the Dipper’s handle forms a curving line that leads to Arcturus and eventually Spica. These are the brightest stars along this imaginary line, and they’re easy to see even in less-than-ideal lighting.
With Arcturus and Spica, Denebola, Beta Leonis, forms a roughly equilateral triangle. It marks the tail of the celestial Lion and is located east of Regulus, Leo’s brightest star. The Sickle, a backward question mark formed by some of Leo’s brightest stars and resembling the Lion’s head and mane, is easily identified. Regulus is the brightest and easternmost of the three stars that form a triangle on the other side of Leo, while Denebola is the brightest and easternmost of the three stars that form a triangle on the other side of Leo.
Denebola has a visual magnitude of 2.1 and is a white A-type main sequence star. It’s also a member of the Great Diamond asterism, which includes Arcturus, Spica, and Cor Caroli, the brightest star in the Canes Venatici constellation. Between Denebola and the brighter Regulus, five other famous Messier galaxies can be found: Messier 65, Messier 66, Messier 105, Messier 95, and Messier 96.
The Spring Triangle’s Vindemiatrix, Epsilon Virginis, is near the center. With an apparent magnitude of 2.8, it is a yellow G-type massive star. After Spica and Porrima, it is the third brightest star in Virgo.
In the region between Vindemiatrix and Denebola, the Virgo Cluster galaxies can be viewed. The spring is the greatest time of year to observe galaxies from northern latitudes.
What is the total number of superclusters?
A supercluster is a massive collection of smaller galaxy clusters or galactic groups that are among the universe’s greatest structures. The Milky Way is a member of the Local Group galaxy group (which includes over 54 galaxies), which is a member of the Virgo Supercluster, which is a member of the Laniakea Supercluster. Superclusters, unlike clusters, grow with the Hubble expansion due to their huge size and low density. There are 10 million superclusters in the observable universe, according to estimates.
Is there a total of eight planets or nine?
Our solar system consists of eight planets, 146 moons, a slew of comets, asteroids and space debris, ice, and numerous dwarf planets, including Pluto. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets.
What are the five galaxies that are the closest to us?
The closest galaxies to Earth are listed in order of increasing distance. Many of the distances are simply estimates, and some could be off by as much as 50%. This list’s distance ranking should only be regarded as a guess. The units of measurement are light years (ly).
Virgo is a Greek god.
Astraea, the Goddess of Innocence and Purity, is the sign of Virgo. Pandora was sent to Earth by Zeus as a punishment for man, according to the creation story. She opened the box the gods had instructed her not to open, releasing the plagues of hate, envy, disease, and other calamities into the world. Of course, Hope did not manage to flee, but life on Earth had become miserable. The gods returned to the heavens one by one to live. The last to leave was Astraea.
In which supercluster does Earth reside?
The Virgo Supercluster of galaxies is where Earth is located in the universe. A supercluster is a collection of galaxies bound by gravity. We are in the Local Group, a smaller group of galaxies within this supercluster. The Milky Way is the second biggest galaxy in the Local Group, behind the Milky Way.
