The section of the "super grand canyon" in this image is approximately 185 miles long.

On the dwarf planet s moon Charon, mammoth cliff faces lurk on a satellite that s just 753 miles in diameter.

NASA recently announced that its New Horizons spacecraft spied a canyon that s both longer and deeper than the Grand Canyon in the American southwest-- a distant geological marvel the space agency is referring to as a super grand canyon.

They re calling the canyon Argo Chasma, and say that it could be as long as 430 miles and as deep as an astonishing 5.5 miles.

Not only that, but Charon s canyon could have cliff faces that are several miles high— plunging vertical faces that could even be taller than the huge cliffs on Miranda, one of Uranus moons.

That makes them possibly the solar system s biggest cliffs, the space agency said.
