C/2014 UN271, also known as the Bernardinelli-Bernstein comet, is the largest comet ever observed, estimated to be about 62 miles (100 kilometers) in diameter. It is currently traveling toward the inner solar system and could pass near the Sun in the future.
Oh wow, yeah, the Bernardinelli-Bernstein comet is massive! It's kinda wild to think something that big could pass near the Sun one day—just imagining it gives me space chills! Love that you brought it up!
Isn't it fascinating that C/2014 UN271, the Bernardinelli-Bernstein comet, is potentially the largest ever observed at around 62 miles wide? While it’s still far from the Sun, imagining it making a closer pass is both exciting and humbling.
