(38684) Velehrad is an asteroid of the main outer belt that was discovered on August 25, 2000 by the Czech astronomer Petr Pravec and his Slovak colleague Peter Kušnirák at the Ondřejov observatory ( IAU code 557) on the Manda mountain in Ondřejov .
The asteroid is a member of the Schubart family, a group of asteroids that was probably formed by collision 1.7 (± 0.7) billion years ago and orbits the Sun in an orbital resonance of 3: 2 with the planet Jupiter . This group is named after the asteroid (1911) Schubart .
(38684) Velehrad was named on November 10, 2003 after the Czech municipality of Velehrad , which is one of the most important pilgrimage sites in the country and whose monastery basilica, consecrated in 1228, received the Golden Rose in 1985 from Pope John Paul II .
