2002 UP11 vs 2015 VF105

See update about this case:
https://groups.yahoo.com/neo/groups/mpml/conversations/messages/31516

=================================
2002 UP11 and 2015 VF105 have similar orbit parameters.
The uncertainty for 2015 VF105 is unknown and I do not find its observations.


Using the Mercury software, it seems that they had a relative close approach on May 8th, 2001 when their nominal relative distance and velocity were:
  • distance 0.00147 AU
  • velocity: ca 5 m/s
Maybe in the future, when further observations will be available, it will be possible to study them looking for a common origin
