Astronomers said it’s traveling 93,000 mph
(150,000 kph), so fast it likely originated outside

kilometers) from the sun and getting closer.
It’s expected to completely sidestep Earth,
remaining beyond Mars’ orbit.
Scientists predict the comet will hurtle past the
sun in December and keep going until it’s back
in interstellar space. It should be visible with
professional telescopes well into next year. Its
nucleus is estimated between 1.2 miles and 10
miles across (2 kilometers and 16 kilometers).
Officially known as C/2019 Q4, the comet was
discovered two weeks ago by an amateur
