Traffic Report  on 26 December '12

Two objects reported inside ten LD

There are two objects reported passing within ten lunar distances (LD) of our planet today. Inside Earth's Hill sphere, radar target 2012 XM55 is outbound from 3.33 to 3.64 LD. And 2012 XP55 comes inside ten LD, traveling from 10.17 to 9.25 LD.

Next known to be approaching is intruder 2012 DA14 (risk-listed radar target), which arrives inside ten LD on February 8th.

This report was generated at 1449 UTC with follow-up in today's DOU MPEC for 2012 XP55.


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.
