792 Metcalfia is a minor planet orbiting the Sun. It was discovered in 1907 by Joel Hastings Metcalf and was named after its discoverer. This is an X-type asteroid in the main belt some 2.62 AU from the Sun. It has a rotation period of 9.17 hours and spans 61 km. The best fit meteorite analog is Gorlovka OC sample RS-CMP-048.^[3]
