Traffic Report  on 29 August '18

Four objects reported inside ten LD

There are four visitors known to be inside ten lunar distances (LD) of Earth today. 1998 SD9, which hasn't been reported recovered yet, comes its closest to our planet on this passage, coming to 4.22 LD at 0726 UTC.

This report was generated at 1945 UTC with follow-up in today's DOU MPEC for outbound 2018 LQ2.



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 29 August '18

The MPC's NEO Confirmation Page has 1 listing

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had one object listed. So far The Tracking News has counted a total of nineteen 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.
