The very wide binary asteroids (VWBA) are a subgroup of binary asteroids that exhibit very long primary periods and, mostly, short secondary periods that are similar to those of the primary of "normal" small binary asteroids. It is unlikely that confirming mutual events will be seen by photometric observations, mostly because the orbital periods of the assumed satellites will be on the order of days. This paper introduces three additional candidates for this subgroup: (215442) 2002 MQ3, 2009 EC, and 2016 BU13. All three are considered to be among the more convincing examples that such systems exist.
极宽双小行星（VWBA）是双小行星的一个子群，其主周期非常长，且大多数情况下次周期较短，与“正常”小双小行星的主周期相似。通过光度观测不太可能确认相互事件，主要是因为假定卫星的轨道周期将在数天量级。本文介绍了该子群的另外三个候选者：(215442) 2002 MQ3、2009 EC和2016 BU13。这三个都被认为是此类系统存在的更具说服力的例子。
