Is A Hidden Planet at the Edge of Our Solar System?

Did we just uncover a new member of our solar system?

Astronomers have spotted 2017 OF201, a newly discovered object with an orbit that stretches from over 4 billion to nearly 150 billion miles from the Sun. For context, even far-out Pluto only reaches about 4.5 billion miles at its most distant!

This icy enigma is estimated to be 300 to 500 miles wide—possibly large enough to be spherical, which could qualify it as a dwarf planet. But there’s still so much we don’t know. Could 2017 OF201 be a hidden world lurking on the solar system’s fringe?

This short video dives into what we know, how it stacks up against Pluto, and why scientists are so intrigued by this distant discovery.
