标题：梅西耶天体
简介
1774年发表的《星云星团表》第一版记录了45个天体，编号由M1到M45。1780年增加至M70。翌年发表的《星云星团表》最终版共收集了103个天体至M103。现时梅西耶天体有110个，M104至M110是后人把由梅西耶及他朋友梅襄（Pierre Méchain）所发现而未被编入《星云星团表》的天体所加入的。
不过后人发现，M40是大熊座中的一对双星，M73（NGC6994）是宝瓶座中的一组小星群，而M102据说于1781年被梅襄“发现”，1783年他又否认，在他给柏林的贝努里的通信中说那是M101的观测结果的重复记录，所以实际上梅西耶等人观测到的深空天体为107个。M40、M73、M102常被称为“遗失的梅西耶天体”。
