Oct. 20 (UPI) -- A rare encounter of two comets this week will have stargazers in awe after nearly a year of no easily seen comets.
Two comets C/2025 A4, nicknamed "Lemmon" and its counterpart C/2025 R2 called "Swan," will reach its closest point to Earth after astronomers discovered the pair this year.
On Monday, the more dim comet Swan will fly near the planet before Lemmon's expected arrival on Tuesday. Their fly-bys are being live-streamed for spectators.
"So far, living in the Northern hemisphere, I could admire C/2025 A6 Lemmon only, but C/2025 R2 Swan is quickly joining the show and we are ready to amaze every astronomy lover with our live feed!" Astronomer Gianluca Masi told Space.com.
It's peak bright spot will be from Monday until Tuesday.
