Traffic Report  on 1 July '12

One object reported inside ten LD

One asteroid is reported traveling within ten lunar distances (LD) of our planet today. Within Earth's Hill sphere, risk-listed radar target 2012 MY2 is outbound from 1.60 to 2.16 LD. No other objects are known to come within ten LD until November.

This report was generated at 1509 UTC with follow-up in today's DOU MPEC for 2012 MY2.


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.
