This also include lost minor planets which have not been observed for many years, or even decades.
As of June 2018, and according to the Minor Planet Center's statistic, there are 256,152[1] or approximately 32% unnumbered minor planets (uMPs) of a total of 779,736,[2] which may differ from JPL Small-Body Database.[3][a]
This partial list contains bodies first observed until 1994, with other lists covering 1995–2004. Due to the increasing number of new principal designations, unnumbered minor planets with a first observation date after 2004 are not listed.

2005–present
Since 2005, an additional 220,000 minor planets have been found (92% of all unnumbered ones). They are not part of this list due to their large number and frequent changes (increase of the number of observations, extension of the observations arc and lowering of the uncertainty parameter). New partial lists may be created in the future, as additional observations ultimately lead to new numberings and to fewer unnumbered bodies. According to the trend in the statistics shown above, the total of bodies first observed in 2005 decreased by 7% from 9,791 to 9,111 within 9 months. This is approximately a 10% decrease per year (see versions of this page from July 2017 and April 2018).
