“The first observed interstellar comet, seen in 2019 on an unbound hyperbolic orbit; Borisov is just passing through and will never return.”

Borisov was found in 2019 as the first interstellar comet — the second visitor from another star after 'Oumuamua. Its coma glowed with carbon monoxide, richer than any local comet's, and it came, it blazed, and its orbit will never bring it back.
It is already outbound, its blue-green coma fading as it leaves the Sun's warmth behind. The Wanderers gave it a proper send-off this time, with tail-ribbons, and it seemed genuinely touched, in the way comets can be.
It will wander the galaxy for eons, a snowball from a dead star system. Perhaps another world's telescopes will catch it someday, and the Wanderers have left a marker in its honor: here passed a stranger who belonged everywhere.

Comets, meteors, asteroids — they owe allegiance to no court and carry messages between all of them. Their creed: arrive, burn bright, leave before they name a holiday after you.
