Minor Bodies in the Outer Solar System:

Magnitudes and Colours

O.R. Hainaut, ESO, H. Boehnhardt, MPS, and S. Protopapa, UMd

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 and normalized to 1 in V) over the visible range are derived for each object.
