(16543) Rosetta is an asteroid of the main belt , which on 5 September 1991 by the Belgian astronomer Eric Walter Elst at de Observatoire Haute-Provence ( IAU code 511) in the southeast of France was discovered.
The celestial body was named after the Rosetta space probe on January 5, 2015 , in memory of its successful arrival at the Churyumov-Gerasimenko comet on August 6, 2014, which it then accompanied for more than two years.
