Provisional designation in astronomy
- 天文学临时编号（天文学临时编号是天体被发现后即时给予的命名，待计算出可靠的轨道资料后，会被正式编号取代。但小行星数量太多，大部分在发现后数年至数十年内都无法计算出轨道，因此长期使用临时名称，无正式命名）
Provisional designation in astronomy

abstract:
Provisional designation in astronomy is the naming convention applied to astronomical objects immediately following their discovery. The provisional designation is usually superseded by a permanent designation once a reliable orbit has been calculated.
