The Minor Planet Bulletin

Click on image to zoom

The Minor Planet Bulletin is the journal for almost all amateurs and even some professionals for publishing asteroid photometry results, including lightcurves, H-G parameters, color indexes, and shape/spin axis models. It is considered to be a refereed journal by the SAO/NASA ADS. All MPB papers are indexed in the ADS.

Print subscriptions are no longer available to individuals. Institutions (e.g., college libraries) can still obtain print copies via a special subscription. See details in MPB 37-4 or contact the editor, Richard Binzel.

Annual voluntary contributions of $5.00 or more in support of the publication are welcome.
Please send a check, drawn on a U.S. bank and payable in U.S. funds, to "Minor Planet Bulletin" and send it to:

Authors Guide and Word Templates   (v.3.0: updated 2024 February 2)
The ZIP file contains the Authors Guide PDF as well as a "starter" paper in Word 2007+ (DOTX).
Those using Word 97 (DOC/DOT) are encouraged to download OpenOffice and convert their files to the most recent Word format (DOCX).
Please read this updated guide since there are a number of changes from previous guides.
  • A new, optional, table is available for those wanting to include physical and discovery information
    in a more accessible way.
    See the announcement in Minor Planet Bulletin 51-2.
  • The Pts column is no longer required and has been removed from the template for the standard table
    to allow more room for the other columns.
  • The phase column should have only two values: for the first and last date in the range.
    If the phase reaches an extrema between those dates, put an asterisk before the first value. For example,
  • Use semicolons to separate names in the references section. For example:
       Smith, J.J.; Jones, A.A. (2019).
    This also applies if using several references to the same author in the text. For example:
    "This asteroid was observed at three previous apparitions (Jones, 2015; 2017; 2018)..."

Issues for the upcoming quarter-year are released on about the 21st of March, June, September, and December. Full issues and individual papers from vol 1 (1973) to present are available via links on this page.

Important: If the ADS bibcode and "Download PDF" links are missing for the latest issue, it is because the ADS has not processed the files. The links will be made available after the ADS processes the files.
If the "Download PDF" link is visible and there is no PDF available, clicking the link will download an arbitrary page. We are working with ADS to make sure all papers are available and, if not, being able to diasable the link. The "Download Full Issue" link does retrieve the correct file.

Vol 1-7 run Jul-Jun. Vol 8-present run Jan-Dec. Only papers indexed in the ADS are included. Earlier volumes often contain more papers than listed here. It's recommended to download the full issue in vol 1-9.
