He compared the photo plates taken at certain time intervals using a blink comparator . The goal was the discovery of the hypothetical Planet X .
Over time, Giclas discovered 17 asteroids, including (1886) Lowell , (2061) Anza, and (2201) Oljato . Oljato is believed to be the original body of the Chi Orionid meteor shower . In addition, he discovered the periodic comet 84P / Giclas .

The asteroid (1741) discovered in 1960 was named Giclas in his honor .
