Short-period comet Olbers (13P/Olbers) is returning to the inner solar system after 68 years. It already reached perihelion (closest point to the Sun) on June 30 and will approach our planet at a minimum possible distance of 283.5 million kilometers on July 20.
In the Northern Hemisphere, the comet will be visible low in the western sky after sunset. For mid-latitude residents, it will be visible about 20–30 degrees above the horizon. The comet’s brightness is between magnitude six and a half and magnitude seven, so it is not visible to the naked eye. However, it can be seen with binoculars.
Olbers’ Comet was first discovered by German astronomer Heinrich Olbers on March 6, 1815. The last time it flew into the inner solar system and came close to Earth was in 1956.
