NOTE:  For the next short while these A/CC news pages will update less often. All discoveries and observing credits will be reported in time, but we may miss some interim impact risk assessments and undercount NEOCP objects, and there may be some days without a traffic report for Earth's Busy Neighborhood.

Asteroid/Comet Connection (A/CC) Resources:

The latest A/CC news is available via framed access, RSS news feed RSS news feed, or redirection.

Navigation tips: Use the << and >> arrows on the menus for each regular section (Observers, Risks, etc.) to move to the previous and next day's news for that section. Use the Index menu item to access specific days through a calendar interface. To keep track of what's new each day, watch the Chronology section.

Traffic Report  on 7 November '19

Eighteen objects reported inside ten LD

Bulletin - 1422, updated 2228 UTC:  Three new discoveries of close passers have been announced today.

Earth passageI D~Size~Inside ten LDNotes
4.02 LD at 0202 UTC Nov. 112019 VX315 m  Nov. 8 - 13 MPEC
6.73 LD at 0728 UTC Nov. 22019 VG49 m  Oct. 30 - Nov. 4 MPEC

Note: 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.

Impact Risk Monitoring  on 7 November '19

Summary Risk Table for Risk Assessments Updated Today   (last checks: NEODyS at 2236 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 and NEODyS listings is 100 years, and both post impact solutions beyond that for some special objects.
For the latest official risk assessments, and for explanations of the terminology, see the NASA/JPL Sentry and NEODyS CLOMON2 risk pages.

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 Once superceded or eliminated, a former impact solution has zero relevance to an object's risk.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.
