Minor Planet Designations

The choice of an appropriate name for a celestial body presents difficulties as the total number of objects increases rapidly and considerably. Eventually one is forced to introduce a numbering system. Very large numbers of objects, however, require the simultaneous use of numbers and names in order to avoid mistakes. In particular, minor-planet nomenclature requires such a procedure. Until the middle of the nineteenth century, nomenclature problems did not exist. Ceres, Pallas, Juno, and Vesta...

Foreword

Parents name their children. Children name their pets. Why Otherwise rational human beings put an inordinate effort into this naming activity. Some names are selected to remind the namer of some other person, place or event. In other instances, the choice of a name means something that sounds good, or is easily spelled. What's the baby's name is much more likely to be asked than some question about its state of health, its weight or the color of its eyes. People are...

Schrutka

Furthermore, Schrutka is an eminent computer of cometary orbits, and he worked extensively on the difficult cases of P Tempel 1, P Tempel-Swift and P Westphal....

He also does extensive orbital work on minor planets, including the...

Statistics and Classification of the Names

This dictionary contains information on all 10038 planets which had been named at the end of 2002. The object (1) Ceres was discovered on January 1, 1801 and is thus the 'eldest' numbered and named planet (50000) Quaoar was discovered only on June 4, 2002 and represents the latest named planet. Overall 52224 planets were numbered up to the end of 2002. The distribution of the discoveries during the more than two centuries can be taken from the cumulative diagram Fig. 1.

Sources of Information

During the second half of the 19th century, the AN were the leading resource in this regard, because they appeared promptly and were distributed widely. The AN were both a scientific journal and a data base. Contributions taken from this source are referred to here by 'AN,' followed by the number of the volume and the column, as well as by the year. All other journals are referred to by the system of abbreviations used in Astronomy and Astrophysics Abstracts. Concurrently with the AN, the BAJ...
