Revision as of 09:56, 27 July 2017

This is the project page for the 2017-revision of the List of unnumbered minor planets (version 13-Jul-2017), for short LoUMP. As of July 2017, there are 239,202 unnumbered minor planets (uMP).

The LoUMP consists of mostly red-linked minor planets listed by year. The earliest designated uMPs (from 1927 to 1992) are listed in a 10-column wiki table (see § Original table) the minor planet are just listed by year in a multi-column format. The list may contain at best 20,000 items, i.e. 10% of all existing uMPs.

Analysis

Currently LoUMP is:

  • table barely useful
  • Incomplete
  • Poorly maintained, technically un-maintainable
  • poorly reference
  • doesn't serve as base table for uMP#R (redirects)
  • ugly (full of redlinks)
  • one single 140 KB-sized page
  • contains numbered MPs (updated from uMP)

Potential:

  • list of long-time uMP
  • When were they observer first? when last?
  • Who observed them first (potential discoverer)
  • what's the dynamic classification
  • link to object pages on MPC, JPL and LCDB

Fields

  • Designation — Unnumbered asteroid's preliminary designation.
  • Epoch — Epoch of the elements represented as the Modified Julian Date (MJD), which is defined as the Julian date - 2400000.5.
  • Orbital elements
    • a: semi-major axis in AU
    • e: eccentricity of the orbit
    • i: inclination of the orbit with respect to the J2000 ecliptic plane in degrees
    • w: argument of perihelion (J2000-Ecliptic) in degrees
    • node: Longitude of the ascending node (J2000-Ecliptic) in degrees
    • M: mean anomaly at epoch
  • H – absolute magnitude
  • G – magnitude slope parameter
  • Ref – orbit solution reference
