Priority List

The List of Suggested Observations

The Priority List classifies the need to observe Near-Earth Asteroids into four categories: urgent, necessary, useful and low priority. This service focuses on newly discovered objects to ensure that the highest possible percentage of these bodies can be recovered at other apparitions.

Near-Earth Asteroids (NEAs) observed at two or more oppositions, but not numbered yet, will eventually be included when they show significant ephemeris uncertainty.

Objects brighter than magnitude 22.0 V and at least 40 degrees of elongation from the sun are eligible for this list according to this PLOT. It is updated on a daily basis using data coming from the Minor Planet Center and the NEODySdatabases.

Each category of this list is represented by an abbreviation and the background color in the first column as indicated. For more information read the "Explanation of Symbols".
