<< Reading:  The University of New Mexico has a news release about a paper on the meteorite NWA 11119, which is described as "the oldest, igneous [volcanic] meteorite ever recorded," formed "prior to the assembly of the terrestrial planets."



Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting about transient natural objects that approach our planet's gravitational sphere of influence (SOI), which has a radius of about 2.41 LD from Earth's center. This puts a focus on some of the most important and very best NEO observation work, representative of the much larger NEO discovery and tracking effort. Object temporal distances are derived by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.

NEOCP Activity  on 7 August '18

The MPC's NEO Confirmation Page has 82 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 82 objects listed. Of these, 45 were "one nighters." So far The Tracking News has counted a total of 89 listings on the NEOCP today.

To learn how observers use the NEOCP, see the Practical guide on how to observe NEOCP object at Suno Observatory by Birtwhistle et al.
