The constellation Pisces is made up of 21 main stars, according to Universe Today. The constellation is the 14th largest constellation, and contains as many as 86 minor stars and other deep-sky objects within its confines.
A:A red giant star ranges from 62 million to 621 million miles in diameter, or 100 to 1,000 times the size of the sun. However, red giants have cooler temperatures than the sun because the energy travels over a larger surface area.
A:The North Star is another name for the star Polaris. It is called the North Star because its location in the Northern Hemisphere remains constant throughout the year as other stars seem to move around it.

A:The brightest star visible from Earth is the sun. Though it is not exceptionally bright by the standards of other stars, its relative proximity to Earth makes it, by far, the brightest object in the sky, with an apparent magnitude of -26.74.
A:According to Sky-Watch, two of the most famous constellations are Ursa Major, the big bear, and Orion, the hunter. Ursa Major stands out because it contains the well-known Big Dipper. Orion is popular because it is near the equator and can be seen from any place on the planet.
A:The constellation Pegasus contains at least 16 stars of magnitude 4 or brighter. Three of the four stars in the Great Square belong to Pegasus. Alpheratz, the star at the northeast corner of the square, was designated as the alpha star of the constellation Andromeda.
A:An observer at the equator will see all of the constellations during the course of one year. The polar constellations Polaris and the Southern Cross appear near the horizon, while the rest pass overhead based on the season.
A:A pattern in the stars is called a constellation. According to the Las Cumbres Observatory Global Telescope Network, the sky is divided into 88 official constellation groups. The constellation groups are referred to as asterisms.
A:The word "Leo" means lion in Latin. The constellation originally represented the ferocious Nemean lion that Hercules strangled to death as one of his 12 labors. According to legend, Zeus was impressed enough to make both of them constellations. Leo is not just a constellation, but one of the 12 constellations that make up the Zodiac. Unlike many constellations, Leo does look something like the creature it depicts.
A:Five facts about Ursa Major are: it is also known as the Great Bear, it is the largest constellation in the sky, it has a companion constellation known as Ursa Minor, the body and tail are part of the Big Dipper and most of Ursa Major is circumpolar. Circumpolar means that the constellation can be seen all year long.
A:Hydra, spanning 1303 square degrees of the sky, is the largest constellation. Hydra is located in the skies of the southern hemisphere and was first named by the Greek astronomer Ptolemy in the second century.
A:While Capella appears to be a single star, it is actually a group of four stars that make up the sixth-brightest object in the night sky. The two stars that make up the brightest part of Capella have a surface temperature comparable to the Sun, about 4,900 degrees Kelvin.
A:Arcturus is one of the brightest and most easily recognized stars in the northwestern sky. Located in the constellation of Boötes, this orange giant is at its most prominent during springtime in the Northern Hemisphere.
A:The constellation Leo is visible most nights of the year to stargazers in the Northern Hemisphere. Leo rises before midnight starting in November and is visible in the evening sky through the following July. August is the only month of the year when Leo is not visible at night.
A:Stars are categorized into seven stellar classes based on their surface temperature, as explained by the HyperPhysics Department at Georgia State University. Each spectral class has its own letter and set of characteristics.
A:There are many places to find pictures of constellations online, including EarthSky, Space.com and HowStuffWorks. It also helps to do a Google image search. It is important to consider that there are different types of pictures available, such as artwork, digital diagrams and real-life photography.
A:Fixed groups of stars are constellations. Constellation names are often given based on an object that the stars resemble when grouped. The names are subjective, such as Orion the Hunter. Though the stars in constellations appear close together, many stars within a constellation are great distances away from each other.
A:The International Astronomical Union recognizes 88 official constellations. Forty-eight of the 88 constellations were described by the ancient Greeks. Constellations are not the same as asterisms, which are simply recognizable patterns of stars such as the Big Dipper.
A:Regulus is found in the constellation Leo, where it also called Alpha Leonis. It is the brightest star in the constellation. It is actually a four-star multiple star system with the pair Regulus B and Regulus C and another pair of Regulus A and an unnamed white dwarf.
