Two Rare Comets Will Appear Soon. Here's How to See Them

Two Rare Comets Set to Appear in the Night Sky In the coming weeks, skywatchers will have the opportunity to witness the rare appearances of two remarkable comets, SWAN and Lemmon. These celestial visitors are set to make their presence known, but their returns are separated by centuries. The SWAN comet, last observed in the early 1700s, is expected to return to our skies in around 700 years. Meanwhile, the Lemmon comet, which was last visible in the 1980s, will take an even longer period of 1,300 years before gracing us with its presence again. These comets, with their long orbits, offer a unique chance for astronomers and enthusiasts to study these ancient remnants of the formation of our solar system. While SWAN and Lemmon may not be as bright as some of their more famous counterparts, their rarity and historical significance make them intriguing targets for observation and scientific investigation.
