it is called Alpha or Alphard which is wierd...
Alpha Hydrae (Alphard) is a red giant star located in the constellation Hydra. It has a diameter that is estimated to be around 50 times that of the Sun.
Menkar (Alpha Ceti) is the alpha star in Cetus.
There is no star that is simply called "Alpha". There are several that have "alpha" in their name, for example Alpha Centauri, Alpha Cruxis, Alpha Canis Majoris, etc. - usually the brightest star in each constellation. Some stars such as Betelgeuse (Alpha Orionis) are not actually the brightest star in the constellation.
LHS 3003 is the closest star to earth from constellation hydra.( 20.67 light years away )
Brittle star
The brightest star is The Persian (alpha alpha), with magnitude 3.11
Polaris (the North star - Alpha Ursae Minoris) is a triple star system, but appears to us as a single star. Alpha Centauri is also another triple star system. And there are many more.
Alpha Centauri is the nearest star system. Its a binary star system of Alpha Centauri A and Alpha Centauri B. If someone asks you what is the nearest star ? then the answer will be "proxima centauri" in my opinion. nearest star: proxima centauri nearest star system: Alpha centauri A and B. Some people believe that its a triple star system of Prixma, Alpha A and Alpha B. centauri.
There is no "star alpha". Alpha is PART of the name of many stars - basically one for each constellation.
go find it
Alphard
There is no star just called "Alpha". Alpha is the first letter of the Greek alphabet, and the main star of each of the 88 constellations is called "Alpha", followed by the name of the constellation (in genitive form). For example, Alpha Canis Majoris, Alpha Centauri, Alpha Geminis, etc.
