Traffic Report on 27 May '18

Six objects reported inside ten LD

There are six transient natural objects known to be inside ten lunar distances (LD) of our planet today. Nearest is newly announced risk-listed intruder 2018 KY2, which exits Earth's sphere of gravitational influence as it travels out from 2.25 to 4.89 LD. Yesterday it passed us at 0.78 LD at 0524 UTC, and went by the Moon at 1.15 LD about 16 hours later.

Neighborhood Traffic - sorted by Earth passage distance, grouped by 1.0, 2.41, 5.0 & 10.0 LD boundaries
Earth passage	I D	~Size	Distance today	Inside ten LD	Notes
0.39 LD May 23	2018 KW1	4 m	5.52 to 7.08 LD	May 17 - 29	intruder, NHATS target
0.78 LD yesterday	2018 KY2	13 m	2.25 to 4.89 LD	May 22 - 29	NEW, intruder, exits Earth SOI, risk - MPEC

2.05 LD May 22	2018 KS	9 m	8.53 to 10.20 LD	May 16 - 27	NHATS target, exits ten LD

2.48 LD May 23	2018 KT2	14 m	8.03 to 9.89 LD	May 18 - 28	NHATS target
3.13 LD May 21	2018 KU2	15 m	9.80 to 11.41 LD	May 15 - 27	NHATS target, exits ten LD

6.10 LD May 29	2018 KN2	27 m	6.77 from 7.74 LD	May 25 - June 3	DOU

This report was generated at 1928 UTC with new discovery 2018 KY2 (MPEC) and with the recovery of distant 2014 HQ124 in today's DOU MPEC, which also has follow-up for three objects in the active traffic tables here plus departed risk-listed 2018 JN. And we have added to this reporting that JPL calculates that 2018 KS, which flew by at 2.05 LD on May 22nd this year, also came by at about 1.61 LD last May and roughly 8.1 LD the May before that.

Approaching Traffic - sorted by 10-LD bubble entry date
Earth passage	I D	~Size	Distance today	Inside ten LD	Notes
9.50 LD May 29	68347 2001 KB67	371 m	10.07 from 11.42 LD	tomorrow - May 30	radar target
5.56 LD June 10	2018 EJ4	186 m	19.91 from 21.22 LD	June 4 - 16	radar/NHATS target - DOU
8.96 LD June 11	2015 DP155	162 m	16.52 from 17.32 LD	June 6 - 15	NHATS target - DOU

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. "Distant" is used here to describe an object that has come within ten LD since A/CC began these traffic reports (2007) but is not now so close. 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 27 May '18

The MPC's NEO Confirmation Page has 19 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had nineteen objects listed. Of these, five were "one nighters." So far The Tracking News has counted a total of 20 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.

Impact Risk Monitoring on 27 May '18

**Summary Risk Table for Risk Assessments Updated Today** (last checks: NEODyS at 2358 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 NASA/JPL Sentry and NEODyS CLOMON2 risk pages.

2018 KY2	JPL Sentry	1641	2075-2115	2	2.22587e-08	-8.94	-8.97	0	JPL: Computed at 05:58 today Pacific time based on 16 observations spanning 4.6050 days (2018-May-21.29062 to 2018-May-25.89566). Diameter approximately 0.013 km. from weighted mean H=27.13.

2018 JN	JPL Sentry	1641	2100-2112	2	1.6534e-06	-6.19	-6.47	0	JPL: Computed at 07:03 today Pacific time based on 146 observations spanning 22.033 days (2018-May-05.42349 to 2018-May-27.45623). Diameter approximately 0.033 km. from weighted mean H=25.08.

Legend: VI# = VI count, Prob Cum = cumulative probability, PS Cum/Max = cumulative/maximum Palermo Scale, TS = Torino Scale (next 100 years)

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.
