"A team of astronomers has discovered the most-distant body ever observed in our Solar System. It is the first known Solar System object that has been detected at a distance that is more than 100 times farther than Earth is from the Sun."

“Farout” is at about 120 astronomical units, its brightness suggests that it is about 500 km in diameter (likely making it spherical) and it has a pinkish hue, a color generally associated with ice-rich objects.
Very nice discovery.
