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]
