610 Valeska is a minor planet, specifically an asteroid, orbiting primarily in the asteroid belt. Discovered in 1906 by Max Wolf. The origin of the name is unknown, but it may be related to the provisional designation 1906 VK.^[2] In Slavic origin, it also means Glorious ruler. Photometric observations provide a rotation period of 4.9047±0.0002 h with a brightness variation of 0.17±0.03 in magnitude.^[3]
