143 Adria is a fairly large main-belt asteroid that was discovered by Austrian astronomer J. Palisa on February 23, 1875, at Pula, and named after the Adriatic Sea, on the coast of which the discovery was made. This dark-coloured asteroid has probably a primitive carbonaceous chondritic composition.
One occultation by Adria has been reported so far, from Japan on August 21, 2000. A somewhat spherical shape measuring 98 × 86 km was observed.
Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave an irregular light curve with a period of 22.005 ± 0.001 hours and a brightness variation of 0.08 ± 0.01 in magnitude.
