Traffic Report  on 4 April '17

Fourteen objects reported inside ten LD

Today fourteen asteroids are reported within ten lunar distances (LD) of our planet. Nearest of these was tiny risk-listed intruder 2017 GM, which was discovered at 0808 UTC yesterday inbound at 4.25 LD and today at 1031 UTC passed us at 0.042 LD -- the fifth closest passage (not resulting in impact) ever tracked by telescope, and the closest since 2016 DY30 at 0.037 LD in February of last year. For comparison, wherever you are, you're at 0.017 LD from Earth's center. Our surprise object ends the day at 2.18 LD in the daytime sky, out of view for ground-based optical telescopes. Next nearest today, also within Earth's SOI, NHATS target 2017 FT102 is outbound from 1.06 to 1.24 LD.

This report was generated at 2016 UTC with two discoveries flagged as "NEW" in the traffic tables here, including 2017 GM, and two more that have already departed: 2017 GH4 (MPEC), which flew past Earth at 8.31 LD on March 27th, and 2017 FB157 (MPEC), which went by at about 6.3 LD on March 15th. Today's DOU MPEC has follow-up for five objects in the traffic tables, including risk-listed NHATS/radar target 2015 TC25, which had radar observation posted late yesterday from October 2015. The DOU also has follow-up for five departed objects: risk-listed 2017 FB102 and NHATS targets 2017 FS91, 2017 FR91, 2017 FR63, and risk-listed 2017 FW90, as well as, from April-May 2014, prediscovery observation of 2014 JH15 (11.33 days added to 12.59-day arc) and post-discovery for 2014 EY24 (39.00 days added to 17.15).

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.

The MPC's NEO Confirmation Page has 55 listings

When last checked at 2358 UTC today, the Minor Planet Center's Near Earth Object discovery Confirmation Page (NEOCP) had 55 objects listed. Of these, fifteen were "one nighters." So far The Tracking News has counted a total of 82 listings on the NEOCP today.

Impact Risk Monitoring  on 4 April '17

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS and JPL 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 JPL NEO Program Sentry and NEODyS CLOMON2 risk pages.

2016 WQ1JPL Sentry2300R E M O V E DJPL: Risk listing removed at 2254 UTC.

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.
