NGC 3766(Caldwell 97)は、ケンタウルス座の散開星団。
1751年から1752年にニコラ・ルイ・ド・ラカーユによって発見された。
視等級は5.3、視直径は約12′で、天体カタログに収録された137個の恒星を含む。距離は、約1,700パーセク。

2013年、スイス・ジュネーブ天文台の天文チームは、NGC 3766にある36個の恒星が、2~20時間の間隔で、光度にして0.1%という僅かな明るさの変化を確認したと発表した。研究チームは、現行の星の等級に適合しない新種の変光星であると主張している。

NGC 3766 (Caldwell 97) is an open cluster located 5,500 light years from the Earth in the constellation Centaurus.

This spectacular group of young stars is the open star cluster NGC 3766 in the constellation of Centaurus. Very careful observations of these stars by a group from the Geneva Observatory using the Swiss 1.2-metre Leonhard Euler Telescope at ESO’s La Silla Observatory in Chile have shown that 36 of the stars are of a new and unknown class of variable star.
