Rider Family: Rider is not the originator of the family, but is the most important.
60km with impact basin on the terminator. More eccentric, more inclined, similar SMA to Rider. Other members of family derived from Riderparent.
2 other members of rider family.

sub-Armstrong: (maybe 2 members in collisional family)
 | 79Mm x 96Mm

eccentricity = (ap-pe)/(pe+ap)
eccentricities of fueling stop asteroids should be <0.1
inclinations of fuel stops should be <2 deg.
