NGC 3766 is an open star cluster in the southern constellation Centaurus. It is located in the vast star-forming region known as the Carina molecular cloud, and was discovered by Nicolas Louis de Lacaille during his astrometric survey in 1751–1752. At a distance of about 1745 pc,[2] the cluster subtends a diameter of about 12 minutes of arc.[3]
There are 137 listed stars, but many are likely non-members, with only 36 having accurate photometric data.[4] Total apparent magnitude of 5.3 and integrated spectral type of B1.7.[2] NGC 3766 is relatively young that is estimated as log (7.160) or 14.4 million years,[3] and approaching us at –14.8 km·s−1.[2] This cluster contains eleven Be stars, two red giants and four Ap stars.[4]
