Erlauntza izar multzoa (Praesepe, M44), Karramarroa (Cancer)
konstelazioan kokaturik dagoen izar kumulu irekia da. Gugandik
600 argi-urtera aurkitzen da eta Lur planetatik gertuen dagoen
izar multzoetako bat da. 600 milioi urte eta 23 argi-urteko
diametroa, grabitazionalki elkar lorturik dauden izar populazio
handia dauka, baturik gutxienez 1000 izar badira, denera 500-600
Eguzki masa osatuz.
Argi kutsadura gabeko zeru ilunetatik, antzinatik ezaguna,
M44 izar multzoa hodei txiki bat bezala ikusten da begi hutsez.
The Beehive Cluster (Praesepe,
M44), is an open cluster in the constellation Cancer. Located
about 600 light-years away, it's one of the closest open
clusters to Earth with an age of around 600 million years and 23 light
years in diameter. It contains a large population of stars,
altogether, the cluster contains at least 1000 gravitationally
bound stars, for a total mass of about 500–600 Solar masses.
Under dark skies with no
light pollution, the Beehive Cluster looks like a small
nebulous object to the naked eye and has been known since
ancient times.
