724 Hapag is a minor planet orbiting the Sun in the asteroid belt[3] that was found by Austrian astronomer Johann Palisa in 1911 and named after the German shipping company Hamburg America Line.[3] It was assigned a provisional name of 1911 NC, then became a lost asteroid until it was rediscovered in 1988 as 1988 VG2 by Tsutomu Hioki and N. Kawasato at Okutama, Japan.[4]
Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico in 2011 gave a light curve with a period of 3.1305 ± 0.0001 hours and a brightness variation of 0.11 ± 0.01 in magnitude.[2]
