144 Vibilia is a large, dark main belt asteroid that was discovered by C. H. F. Peters on June 3, 1875, from the observatory at Hamilton College, Clinton, New York. Peters named it after Vibilia, the Roman goddess of traveling, because he had recently returned from a journey across the world to observe the transit of Venus. Peters also discovered 145 Adeona on the same night.
Based upon its spectrum, this object is classified as a C-type asteroid. This means it probably has a primitive carbonaceous composition. It is the only large member of the Vibilia asteroid family.
Vibilia has been observed to occult a star twice so far (in 1993 and again in 2001).
13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 131 km. Based upon radar data, the near surface solid density of the asteroid is 2.4+0.7
−0.5 g cm−3.
