Dates of Last Observation

As a convenience for observers, we listthe dates of last observation forunusual minor planets.

Unusual Minor Planets

Lists ofunusual minor planets(i.e., those whose orbit approachesthat of the earth or whose orbit lies in the outer solar system). Theselists are available in two forms: sortable table format and plain ASCII.

• Sortable table format:
  • List of Atens
  • List of Apollos
  • List of Amors
  • List of Centaurs and Scattered-Disk Objects
  • List of Transneptunian Objects
  • Other unusual objects
  • PHAs
• Plain ASCII format:
  • List of Atens
  • List of Apollos
  • List of Amors
  • List of Centaurs and Scattered-Disk Objects
  • List of Transneptunian Objects
  • Other unusual objects
  • PHAs
  • List of (comets and) NEO designations assigned in the past year.

Forthcoming Close Approaches to the Earth

A list of close approaches to the earthby comets and near-earth minor planets in the next 33 years.

• Also available is alist of PHA close approaches to the earth through the end of the 21st century.

Closest Approaches to the Earth

Alist of the closest approaches to theearth by minor planets.

• Interactive geocentric apparent motion diagrams are available for selected objectshere.

Trojan Minor Planets

Lists ofTrojan minor planets.

Plots of the Solar System

Views (updated daily) of theinner orouter solar system. A similar view of theinnermost region of the solar system is also available.

Distribution of the Minor Planets

Plots showing how the orbital elements of the minor planets are distributed.

Correspondences Of Minor Planet Designations

Analphabetical list of names of numbered minorplanets is available.

Discoverers of the Numbered Minor Planets

The numbered minor planets have been discovered by a large numberof individuals and teams. Lists of the discovery statistics are availableordered bynumber of discoveries andalphabetically. Also available is a listof the number of discoveries made at themost prolific discovery sites.Discovery circumstances are alsoavailable, as isa breakdown ofnumbered discoveries by year.

Provisional Designations

Information on thenumber of new-style provisionaldesignations (and the yearly and half-monthly breakdowns of the total)assigned by the Minor Planet Center (and its predecessors).

Observatory Codes
