Traffic Report  on 4 July '12

One object reported inside ten LD

There is one visitor reported within ten lunar distances (LD) of Earth today. Radar target 2012 MY2 exits Earth's Hill sphere, passing from 3.59 to 4.36 LD. No other object is known to come inside ten LD until November.

This report was generated at 1623 UTC.


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.
