Traffic Report  on 15 January '17

One object reported inside ten LD

Today one transient natural object is known to be inside ten lunar distances (LD) of our planet. 2017 AJ13 is headed away from 6.83 to 7.66 LD, while NHATS target 2016 YC8 will arrive inside the ten LD space tomorrow.

This report was generated at 1738 UTC.



Notes: Ten times the distance to the Moon (ten LD) has no astronomical importance but is a useful boundary for reporting on transient natural objects that approach the actually significant 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 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 15 January '17

The MPC's NEO Confirmation Page has 46 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 46 objects listed. Of these, seven were "one nighters." So far The Tracking News has counted a total of 54 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.
