Traffic Report  on 14 December '12

Ten objects reported inside ten LD

Ten asteroids are reported to be less than ten lunar distances (LD) from our planet today. Within Earth's Hill sphere, intruder 2012 XB112 (risk-listed radar target) comes inside the Earth-Moon system, moving in from 1.02 to 0.82 and then out to 0.90 LD from Earth. Newly announced risk-listed intruder 2012 XL134 is inbound from 3.77 to 1.63 LD and newly discovered 2012 XP134 from 3.39 to 1.70 LD. And risk-listed 2012 XH112 enters Earth's Hill sphere, passing from 5.73 to 2.82 LD.

More distantly, radar target 2012 XM55 is inbound from 6.96 to 6.39 LD and risk-listed 2012 XM16 from 8.91 to 6.25 LD. Newly announced 2012 XN134 is outbound from 4.68 to 5.22 LD, 2009 BS5 is calculated with some uncertainty to be moving away from 9.0 to 9.5 LD, and two objects exit from being inside ten LD. Intruder 2012 XE54 travels from 7.65 to 10.60 LD and 2012 XJ112 from 9.24 to 11.66 LD.

Up next, 2012 XP55 arrives inside ten LD on December 26th.

This report was updated at 2321 UTC to note radar observation of passing intruder 2012 XB112.

This report was previously updated at 2148 UTC with six new discoveries announced since one much earlier today. These are 2012 XP134 (MPEC), 2012 XN134 (MPEC), 2012 XL134 (MPEC), and departed objects 2012 XO134 (MPEC), 2012 XK134 (MPEC), and 2012 XJ134 (MPEC).

Today's DOU MPEC carries observations of 2012 XJ112, 2012 XB112, 2012 XM55, 2012 XM16, and departed objects 2012 XB133, 2012 XH, and radar target 2010 JK1. (JPL's most recently published orbit solution for JK1 is from November 27th. Such delays are not unusual for radar targets.)

Today's first traffic report was posted at 0254 UTC with departed new discovery 2012 XB133 (MPEC).


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.

Impact Risk Monitoring  on 14 December '12

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL at 2359 UTC)
See the CRT page for a list of all objects rated recently as risks and our ephemerides page for a list of risk-listed objects under current observation.
The time horizon for JPL is 100 years from today and for NEODyS is usually the year 2090. Both also post impact solutions beyond 100 years for a few special objects.
For the latest official risk assessments, and for explanations of the terminology, see the JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from a variant orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" to learn more.
