1000 Piazzia was named as part of trio honoring the events surrounding the discovery of Ceres in 1801.[16] A person named Carl Friedrich Gauss who computed the orbit of Ceres, and Heinrich Wilhelm Matthias Olbers who found it again later that year after it has passed behind the Sun.[16] In honor of them, 1001 Gaussia for Gauss and 1002 Olbersia for Olbers were named along with 1000 Piazzia.[16] In the next few years only three more astronomical bodies were found between Mars and Jupiter, Pallas, Juno, and 4 Vesta, however it would be 37 years before another asteroid was found, 5 Astraea in 1845.[16]
By 1868, 100 asteroids had been discovered, however it would not be until 1921 that the 1000th was discovered. The rate accelerated in the 20th century and the ten thousandth would be discovered in 1989.
