Feast your eyes on the first interstellar comet ever directly observed – TechCrunch

“It’s traveling so quickly it practically does not care that the Sun is there,” said UCLA’s David Jewitt, who leads the Hubble group seeing 2I/Borisov. Basically the angle it’s coming in, plus the speed at which it’s taking a trip, indicate it can’t perhaps be in even a super-wide orbit of the Sun. Fascinating in its own way, but comets are so dynamic: clouds of dust and ice surrounding a much smaller sized core. Note that these interstellar visitors are really believed to be quite typical, with perhaps thousands in the solar system at any given moment.

Keep in mind that these interstellar visitors are really thought to be quite common, with maybe thousands in the solar system at any given minute.
