, best known for his 1898 claim of a second moon of Earth as well as a system of tiny moons. It is widely held to be false.

He claimed that it was not normally visible with the naked eye but predicted it would be visible between 2 and 4 February 1898. Twelve claims were made to have seen it at that time but were later proven fraudulent or mistaken by astronomers W. Winkler and Baron Ivo von Benko who had been monitoring the area at the time. Waltemath also claimed that the moon had been sighted previously by Adolphus Greely
Adolphus Washington Greely (March 27, 1844 – October 20, 1935) was a United States Army officer and polar explorer. He attained the rank of major general and was a recipient of the Medal of Honor.

'' it is 427250 km (265480 miles) away from earth, closer than Waltemath's previous moon, and 746 km (464 miles) in diameter. As Waltemath's claim of the second moon was generally considered to be false, reactions to the third were mostly scoffed at; that same article in ''Science'' considered that "''Perhaps it is also the moon presiding over lunacy''".
