Heinrich Wilhelm Matthias Olbers (Bremen) discovered the comet on March 6, 1815. Its orbit was first computed by Carl Friedrich Gauss on March 31, Friedrich Bessel calculated an orbital period as 73 years, later as 73.9 years, calculations by other astronomers during that era resulted anywhere between 72 and 77 years.
The comet was last detected in 1956. It will next come to perihelion on June 30, 2024. the comet will be closest to the Earth on January 10, 2094 when it passes at a distance of 0.756 AU.
