| 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". | Urgent | |
| Necessary | ||
| Useful | ||
| Low priority |
