These pages contains photometric information on Minor Bodies in the
outer Solar System, i.e. comets, transneptunian objects, centaurs and
trojans. Satellites of MBOSSes are included, but not the giant planets'.
The methods used are described in detail in the companion paper,
Hainaut, Boehnhardt & Protopapa (2012), which is an update of the
original paper on this topic, by Hainaut & Delsanti (2003).
The visible and near-infrared magnitudes and colours are collected
from the literature. Only measurements identified as "simultaneous"
(i.e. within less than about an hour from each-other) are combined
into colours, so not to introduce rotation artifacts.
The number of measurements is now large enough so that data-sets with
an internal high dispersion can be safely identified and removed. The
rejection method is safe for individual outliers; it is described in the paper.
The object type is defined using physico-dynamical classes
derived from those from Gladman et al. in the SSBN book
[ADS].
The absolute R magnitude and the spectral gradient (slope of
the reflectivity spectrum derived from the colours) over the visible
range are derived for each object.
Database Tables
The current status of the photometric database is listed below. The data

Plots
The plot page contains an extensive
collection of colour-colour diagrams, histograms, reflectivity
spectra, etc... They are available as GIF previews and vectorial EPS files.
Everything
All the plots and tables are available as one large
PDF document.
Reference databases
The original, frozen databases are available here for reference:
MBOSS-1, from the original Hainaut & Delsanti 2003 (PDF, ADS), and
MBOSS-2 (ASCII) from the current paper.
