3I/ATLAS: Observatory That First Spotted Exocomet Compares The 3 Interstellar Objects Ever To Enter Solar System

We’re about to find many more interstellar interlopers
Named #3IATLAS, a rogue comet that arrived recently is the third interstellar object #astronomers have detected within our Solar System, following #1IOumuamua and #2IBorisov discovered in 2017 and 2019. Scientists think interstellar objects routinely transit among the planets, but #telescopes have only recently had the ability to find one. For example, the #telescope that discovered Oumuamua only came online in 2010.

I think tomorrow is #2IBorisov day, no? Interstellar object number two reaches perihelion out past Mars.
