Traffic Report  on 21 September '13

Three objects reported inside ten LD

Three objects are reported to be inside ten lunar distances (LD) of Earth today. Within out planet's Hill sphere, tiny risk-listed intruder 2013 RZ53, possibly an artificial object, is moving away from 1.01 to 1.32 LD. More distantly, 2013 RF74 is outbound from 7.74 to 9.55 LD and 2013 RM73 leaves ten LD, passing from 9.11 to 11.27 LD.

This report was generated at 1458 UTC with follow-up in today's DOU MPEC for 2013 RF74 as well as observation of distant radar target 152664 1998 FW4.

Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Earth's Hill sphere (of gravitational influence) is estimated to extend out to around 3.89 LD. Object distances are interpreted by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.
