He married the anthropologist Hilda Kuper, with whom he had two daughters: the international human rights lawyer Dr Jenny Kuper and the painter and sculptor Mary Kuper. Kuper was an active member of the Liberal Party of South Africa during the 1950s and some of his involvements are detailed in Alan Paton's book "Journey Continued". During the 1960s, Kuper moved to Los Angeles, California, United States, where he took up teaching and researching at UCLA. His publications include "The Pity of it All", "Passive Resistance in South Africa", and "The Prevention of Genocide". Kuper was a founding member of the Council of the Institute on the Holocaust and Genocide and the Liberal Party of Natal. 
Objects 100 and 50 km in radius (200 km to 100 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the gas giants in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. Asteroid spectral types are mostly Tholen, but some might be SMASS. 
The scattered disc, which overlaps the Kuiper belt but extends much further outwards, is thought to be the source of short-period comets. Scattered disc objects are believed to have been ejected into erratic orbits by the gravitational influence of Neptune's early outward migration. Most scattered disc objects (SDOs) have perihelia within the Kuiper belt but aphelia far beyond it (some have aphelia farther than 150 AU from the Sun). SDOs' orbits are also highly inclined to the ecliptic plane and are often almost perpendicular to it. Some astronomers consider the scattered disc to be merely another region of the Kuiper belt and describe scattered disc objects as "scattered Kuiper belt objects". Some astronomers also classify centaurs as inward-scattered Kuiper belt objects along with the outward-scattered residents of the scattered disc. 
In American Sign Language classifier constructions are used to express position, stative description (size and shape), and how objects are handled manually. The particular hand shape used to express any of these constructions is what functions as the classifier. Various hand shapes can represent whole entities; show how objects are handled or instruments are used; represent limbs; and be used to express various characteristics of entities such as dimensions, shape, texture, position, and path and manner of motion. While the label of classifiers has been accepted by many sign language linguists, some argue that these constructions do not parallel oral-language classifiers in all respects and prefer to use other terms, such as polymorphemic or polycomponential signs. Examples: 1 hand shape: used for individuals standing or long thin objects A hand shape: used for compact objects C hand shape: used for cylindrical objects 3 hand shape: used for ground vehicles Y hand shape: used for aircraft  
[[File:TheIrregulars Colours.svg|thumb|300px|This diagram illustrates the differences of colour in the irregular satellites of Jupiter (red labels), Saturn (yellow) and Uranus (green). Only irregulars with known colour indices are shown. For reference, the centaur Pholus and three classical Kuiper belt objects are also plotted (grey labels, size not to scale). For comparison, see also colours of centaurs and KBOs. ]]The colours of irregular satellites can be studied via colour indices: simple measures of differences of the apparent magnitude of an object through blue (B), visible "i.e." green-yellow (V), and red (R) filters. The observed colours of the irregular satellites vary from neutral (greyish) to reddish (but not as red as the colours of some Kuiper belt objects). Each planet's system displays slightly different characteristics. Jupiter's irregulars are grey to slightly red, consistent with C, P and D-type asteroids. Some groups of satellites are observed to display similar colours (see later sections). Saturn's irregulars are slightly redder than those of Jupiter. The large Uranian irregular satellites (Sycorax and Caliban) are light red, while smaller Prospero and Setebos are grey, as are Neptunian sateliites Nereid and Halimede.
