Traffic Report  on 11 May '19

Twelve objects reported inside ten LD

There are twelve asteroids reported to be less than ten lunar distances (LD) from Earth today. The nearest, risk-listed 2019 JJ3, exits our planet's SOI as it slides out from 2.04 to 3.38 LD.

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 11 May '19

The MPC's NEO Confirmation Page has 137 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 137 objects listed. Of these, 42 were "one nighters." So far The Tracking News has counted a total of 151 listings on the NEOCP today.
