Traffic Report  on 27 April '13

One object reported inside ten LD

One asteroid is reported to be within a radius of ten lunar distances (LD) from Earth today. 2013 GH66 is outbound from 6.88 to 7.26 LD. No other objects are known to be coming inside ten LD until late July.

This report was generated at 1433 UTC.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. 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.
