13P/Olbers is a periodic comet in our solar system.
Heinrich Wilhelm Matthäus 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 a, later as 73.9 a, calculations by other astronomers have resulted anywhere between 72 and 77 a.
The comet was last detected in 1956, it will be closest to the Earth on January 10, 2094.
There is some speculation[4] that 13P/Olbers has an associated meteor shower on Mars coming from the direction of Beta Canis Major.
