'''NGC 2232'''是一个位于[[天球赤道]]附近的[[麒麟座]]，以麒麟-10为中心的一个明亮的[[疏散星团|疏散星团]]。<ref name="nightsky" /> 它在[[猎户座大星云]]附近的[[古爾德帶]]，<ref name=Currie2008/>距太阳约1060光年。<ref name=Kharchenko2005/>该星系的平均[[徑向速度]]为{{Val|26.6|0.77|u=km/s}}。<ref name=Monroe2010/> NGC 2232 是距离太阳最近的疏散星团之一，是一个研究年轻恒星向[[主序星]]过渡的一个潜在目标之一。<ref name=Orban2004/>

星团的角半径为{{Val|36|ul=arcminute}}，核心角半径为{{Val|7.2|u=arcminute}}。是一个由20个集中恒星组成的稀疏簇<ref name=Kharchenko2005/> 。它被认为是一个超级太阳星团，该星团的恒星的铁含量通常比太阳更高，[[金屬量|金屬量]]为{{Val|0.22|0.09}}或{{Val|0.32|0.08}}，取决于所做的假设。<ref name=Monroe2010/> 至少四个恒星[[紅外過量]]波长为8μm，为暖尘埃，其中HD 45435的波长超过24μm.，可能说明恒星处于早期演变阶段。<ref name=Currie2008/>该星团中只有一颗恒星是[[特殊恆星]]。<ref name=Jenkner1987/>
