The names of a majority of the visible stars are in, or derived from, Arabic. This is because the records from the Greek and Egyptian astronomers who originally cataloged all of the stars were lost in Europe after the fall of Rome. Those books, such as the Almagest, were only preserved in Egypt, and copies were captured by the Spanish from Arabic libraries in Spain and re-introduced into Europe at the beginning of the Renaissance.

What language produced the names of most of your constellations?
Greek to Latin are the 88 Astronomical Union's constellation names, however, most stars have Arabic names due to Classical names being lost after the fall of the Roman empire. The brightest stars have the names that they always had however, Vega, Sirius, etc, but Aldebaran, Hamal are Arabic. Star names such as Alpha Centauri, Gamma Cassopeia are Greek, Bayer names.
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
What is true of the hottest stars They are the brightest stars. They are the farthest from the earth. They are the least massive. They include the earth's sun.?
None of them.The hottest stars are the most luminous.
Which region contains the most stars in the HR Diagram?
Several regions of the HR diagram have been given names, although stars can occupy any portion. The brightest stars are called supergiants. Star clusters are rich in stars just off the main sequence called red giants. Main sequence stars are called dwarfs.
How are the stars in a constellations named?
The brightest stars in the sky all have names that were given by ancient civilizations. Most of the names we use today have been passed down from Greek and Roman cultures. These include star names such as Beteleguese (in Orion), Sirius (in Canis Major), Arcturus (in Bootes), Spica (in Virgo), and many others. Another way of naming stars is to assign a letter from the Greek Alphabet (Alpha as the brightest) along with the name of the constellation they are in. For instance the brightest star in Leo would be Alpha Leonis. The second brightest would be Beta Leonis, etc. One thing to know is that the only organization that has the official rights to naming stars is the International Astronomical Union. It is simply not possible to have a star named after a person. You may pay $50 to some group for a fancy certificate, but no one will ever refer to that star as "Edna Garffdangle".

A star with an ancient Arabic name is?
The brightest stars in the sky of Earth are also the ones with the most ancient names. Names such as Betelgeuse, Achernar, Sirius, Deneb, and Algol are usually Arabic, dating from around the tenth century when Arab astronomy flourished. Less-bright stars were usually not given proper names at the time, and were thus harder to talk about.
What are the names of the two brightest stars in the constellation Draco the dragon?
The brightest is Gamma Draconis or Eltanin or Etanin (magnitude 2.2) The second brightest is Beta Draconis or Rastaban (magnitude 2.8) Traditionally the star designated as Alpha is the brightest in most constellations but not in Draco. Alpha Draconis or Thuban and is magnitude 3.6
Which Stars are the Brightest Stars you know?
The actual brightest star is R136a1. It is more than 8 million times as bright as the sun and is also the most massive star. The brightest star in the nighttime sky is Sirius.
What is the biggest and the brightest stars in the solar system?
Most likely the sun.
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
What are the different names of the stars?
1. Sun2. Sirius3. Rigel4. Betelgeuse5. Procyon
What is true of the hottest stars They are the brightest stars. They are the farthest from the earth. They are the least massive. They include the earth's sun.?
None of them.The hottest stars are the most luminous.
What does a stars Greek letter designation tell us that its ancient Arabic name?
The Greek letter designation is a Greek letter followed but the possessive form of the constellation name (for example, alpha-Orionus). In most cases (Ursa Major being a notable exception), the brightest star in a constellation designated with the Greek letter alpha, the second-brightest with the Greek letter beta, and so on. Thus the Greek letter designation gives information about both relative brightness and location. There is no connection between the Greek letter designation and ancient Arabic names.

Which main sequence stars are most massive?
Most stars in the universe today are main sequence stars. Sirius A is the brightest star in the nighttime sky. The sun is the most massive main sequence star in the universe today.
