当大的小行星体或慧星撞击月球表面时，其表面物质的喷射可以达到逃逸月球的速度（2.4km/s）从而进入宇宙空间，其中一部分为地球所捕获并降落到地球上，这表明月球陨石与月球表面的冲击成坑事件密切相关，特别是大的小行星体低角度撞击更有利于喷射物质的逃逸。由于月球经过岩浆分异作用，所以月球陨石属无球粒陨石。2
发现历史和数量
月球陨石的发现开始于20世纪80年代。在Apollo和Luna计划采样返回10年之后，于1982年才确认第一块月球陨石ALHA 81005。这块陨石是美国陨石考察队（ANSMET）在南极Alan Hill山区发现的，该陨石样品被送往美国休斯顿空间中心进行处理和保管，由于该中心负责月球样品处理和保管，研究人员熟悉月球样品，他们在处理该样品时发现其结构特征与月球样品非常相似，而促使他们考虑到ALHA 81005陨石可能来自月球。其实，在此样品之前，日本南极考察队在Yamato发现了一块月球陨石Y791197，由于当时缺乏经验，这块陨石被误认为是钙长辉长无球粒陨石（Eucrite）。据确认时间顺序，Y791197、Y82192和Y82193分别是第二、三、四块月球陨石。此外，Y793169和EET87521陨石曾被误认为是钙长辉长无球粒陨石，后来被确认为月球陨石。1
月球陨石稀少，发现过程非常缓慢。到1993年，才发现12块月球陨石，而且主要来自南极，南极之外仅在澳大利亚发现一块Calcalong Creek。到2000年，月球陨石数量达到了31块，同样，绝大部分来自于南极。由于Calcalong Creek陨石曾在市场上标价4万美元/g，这激发了民间陨石爱好者对月球陨石的极大兴趣，到1997年，在南极以外发现了第二块月球陨石。2000年之后，民间在非洲沙漠地区寻找月球陨石取得了巨大成功，月球陨石数量和质量也随着飙升。至2013年，已公布发现月球陨石165个，总重量65.2kg，如考虑成对陨石，这些陨石代表了81次陨石降落，其中10个月海玄武岩、50个斜长岩、21个玄武质斜长质混合角砾岩。在数量上，32（块（成对19块）月球陨石发现于南极，其他148块发现于南极之外的沙漠地区。在数量上，沙漠月球陨石占月球陨石的绝大部分。1
岩石类型
由于缺乏大气层的保护，月球在历史上经历了强烈的撞击作用，因此，月球上布满了大大小小的撞击坑，同时，在月球表面形成了一层数米至20多米厚度不等的月壤。与此相似，月球陨石除少量具有完整结晶结构玄武岩外，其余大部分月球陨石均为碎屑岩。根据岩石结构和矿物组合，月球陨石可分为玄武岩、斜长岩和玄武岩-斜长岩质混合角砾岩等三类，这与月球岩石的月海玄武岩、高地斜长岩和过渡地区的混合角砾岩相对应。另外，根据岩石学和化学成分特征，月球陨石主要有三种端元类型物质组成，即角砾岩化斜长岩、玄武岩和角砾岩化玄武岩、苏长岩成分的冲击熔融玻璃即月球岩石中的克里普岩。1
