Scout: NEOCP Hazard Assessment

Data Table

Scout data are about unconfirmed objects and all information should therefore be treated as potentially unreliable.

The following table contains NEOCP objects analyzed by Scout. Because of the generally short observation arcs and the uncertain quality of the astrometry, the reported impact ratings and scores are meant to identify interesting objects rather than provide a rigorous probability assessment.

Object
NEOCP temporary object designation
#obs
Number of observations available
Arc (h)
Length of the observation data arc in hours
RA (hh:mm)
Right Ascension of the current ephemeris (hh:mm, J2000)
Dec. (deg.)
Declination of the current ephemeris (degrees, J2000)
V (mag)
V-band magnitude estimate of the current ephemeris (mag)
Rate (″/min.)
Plane-of-sky rate of motion (arc-seconds per minute)
Elong. (deg.)
Solar elongation of the current ephemeris (degrees)
POS Unc. (′)
1-sigma uncertainty in the plane-of-sky of the current ephemeris (arc-minutes)
POS Unc.+1 (′)
1-sigma uncertainty in the plane-of-sky one day after the current ephemeris (arc-minutes)
H
Absolute magnitude
Impact Rating
A rating to characterize the chances of an Earth impact (0=negligible, 1=small, 2=modest, 3=moderate, 4=elevated)
CA Dist. (LD)
Close-approach distance to Earth in lunar distances (LD)
MOID (au)
Minimum distance between the orbits of Earth and the object (au)
Vinf (km/s)
Asymptotic velocity relative to Earth (when defined)
NEO
Score for the object being a NEO (0-100)
NEO > 1km
Score for the object being an NEO larger than 1 km in diameter (0-100)
PHA
Score for the object being a PHA (0-100)
IEO
Score for the object being an IEO, Interior Earth Object (0-100)
Geo.
Score for the object having a geocentric orbit (0-100)
TJ < 3
Score for the object having a Jupiter tisserand invariant less than 3, comet-like orbit (0-100)
RMS
RMS of the weighted residuals for the best fitting orbit
