- Object
- Full designation of the target NEA (near-Earth asteroid).
- Orbit ID
- ID of the JPL NEA orbit used in this analysis
- H (mag)
- Absolute visual (V-band) magnitude in magnitude units.
- Estimated Diameter (m)
- Estimated diameter in meters showing the minimum and maximum likely size based on assumed maximum and minimum albedos of 0.60 and 0.03, respectively. If the size is "known", a single value is shown instead. If a single value is shown, it should still be considered an estimate.
- OCC
- Orbit Condition Code of the NEA's orbit when NHATS-analysis was performed, where 0 implies a well-determined orbit and 9 implies a very poorly-determined (highly uncertain) orbit.
- Min. delta-V [delta-V, dur.] (km/s), (d)
- The total delta-V in km/s and corresponding duration in days for the trajectory solution with the minimum total delta-V.
- Min. Duration [delta-V, dur.] (km/s), (d)
- The total delta-V in km/s and corresponding duration in days for the trajectory solution with the minimum possible total duration.
- Viable Trajectories
- The total number of NHATS-compliant trajectory solutions. This value serves as a proxy for accessibility of the NEA.
- Next Optical Opportunity (yyyy-mm [Vp])
- The year and month (yyyy-mm) during which the asteroid will next be observable optically from the Earth at a magnitude of 24.0 or brighter, solar elongation > 60 deg and plane-of-sky (POS) uncertainty < 1.5 deg. When the latter limit is exceeded the object is considered lost, in which case it can only be observed via a serendipitous re-discovery by an asteroid survey program. Leading and trailing '?' indicate when such a survey re-discovery may be possible. [Vp] is the predicted peak magnitude during the opportunity. Follow this link for more details.
- Next Arecibo Radar Opportunity (yyyy-mm [SNR])
- The year and month (yyyy-mm) of the next optimal Arecibo radar observing opportunity. To be considered observable, the asteroid must be at an accessible declination, the signal-to-noise ratio (SNR) must be at least 10, and the plane-of-sky uncertainty must be less than 0.75 arc-min. [SNR] indicates the peak SNR value during the opportunity. Follow this link for more details.
- Next Goldstone Radar Opportunity (yyyy-mm [SNR])
- The year and month (yyyy-mm) of the next optimal Goldstone radar observing opportunity. To be considered observable, the asteroid must be at an accessible declination, the signal-to-noise ratio (SNR) must be at least 10, and the plane-of-sky uncertainty must be less than 0.75 arc-min. [SNR] indicates the peak SNR value during the opportunity. Follow this link for more details.
