The Centaurus Cluster (A3526) is a cluster of hundreds of galaxies, located approximately 170 million light-years away in the Centaurus constellation. The brightest member galaxy is the elliptical galaxy NGC 4696 (~11m).
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677.
Both mission targets show evidence for rings and/or cometary activity. Chiron is the second largest known centaur, by diameter, after 10199 Chariklo. Activity was identified in the past, which appears to feed its rapidly-evolving ring system. [4] [5] [6] SW1 is the most active centaur known, averaging over 7 periods of activity each year. [7]
10199 Chariklo / ˈ k ær ə k l oʊ / is the largest confirmed centaur, a class of minor planet in the outer Solar System.It orbits the Sun between Saturn and Uranus, grazing the orbit of Uranus.
In 2010, VBSDC collected data on dust past 18 AU (1.67 billion miles), which is the distance the Pioneer 10 and Pioneer 11 dust counters stopped working. [2] Five other spacecraft have carried dust detectors beyond the asteroid belt including Pioneer 10, Pioneer 11, Ulysses (heliocentric orbit out to the distance of Jupiter), Galileo (Jupiter Orbiter), and Cassini (Saturn orbiter).

Centaur-C flew three times between 1964 and 1965, [47] with two failures and one launch declared successful although the Centaur failed to restart. This version was also powered by two RL10A-3 engines. [47] Centaur-D was the first version to enter operational service in 1965 , [47] with fifty-six launches. [48]
Centaur carrying off a nymph (1892) by Laurent Marqueste (Tuileries Garden, Paris) Jerome's version of the Life of St Anthony the Great , written by Athanasius of Alexandria about the hermit monk of Egypt, was widely disseminated in the Middle Ages; it relates Anthony's encounter with a centaur who challenged the saint, but was forced to admit ...
