9954 Brachiosaurus is a main belt asteroid. It orbits the Sun once every 4.58 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9954;orb=0;cov=0;log=0#elem|title = 9954 Brachiosaurus (1991 GX7)|work = JPL Small-Body Database Browser]

Discovered on April 8, 1991 by E. W. Elst, it was given the provisional designation "mp|1991 GX|7". It was later renamed "Brachiosaurus" after Brachiosaurus, a large herbivorous dinosaur. ["MPC 47166" Minor Planet Center]
