Comet 13P/Olbers will reach its perihelion (the closest point on its orbit to the Sun) on Sunday 30 June 2024, when it will be approximately 1.18 AU from the Sun (i.e. 118% of the distance from the Sun to the planet Earth, or 176 525 500 km). At this time the comet will be 1.92 AU from the Earth, in the constellation of Lynx, having a magnitude of 6.1, which means that it may be possible to view it from the Northern Hemisphere with a small pair of binoculars in the early evening, although it will be no more than 13° above the horizon at dusk, and set shortly thereafter.

Comet 13P/Olbers was discovered by German astronomer Heinrich Wilhelm Matthias Olbers on 26 April 1815. The designation 13P/Olbers implies that it was discovered by Olbers, that it is a Periodic Comet (defined as a comet with a period of less than 200 years, beyond which it becomes impossible to predict the return of comets reliably), and that it was the 13th such body discovered.
Comet 13P/Olbers has an orbital period of 67.9 years and a highly eccentric orbit tilted at an angle of 44.6° to the plain of the Solar System, that brings it from 1.16 AU from the Sun at closest perihelion (116% of the distance between the Earth and the Sun, and inside the orbit of Mars) to 32.1 AU from the Sun at aphelion (32.1 times as far from the Sun as the Earth or a little outside the orbit of the planet Neptune). As a comet with a period of less than 200 years, 13P/Olbers is considered to be a Periodic Comet, and a comet with a period of more than 20 years but less than 200 years, it is also considered to be a Halley-type comet.
