292 Ludovica is a main belt asteroid. It was discovered by the Austrian astronomer Johann Palisa on 25 April 1890 in Vienna. The reason for this name selection is unknown.[6]
Photometric data collected during 2010 was used to produce a light curve for 292 Ludovica, revealing a rotation period of 8.90±0.05 h with a brightness variation of 0.35±0.05 in magnitude. This result is consistent with previous studies.[7]
