Dwarf Planets

'Oumuamua, the first known visitor from interstellar space, was likely a pancake-shaped chip off a Pluto-like world.

For a few months in 2018, as NASA's Dawn spacecraft used up its last drops of fuel, it gave scientists an incredibly detailed look at one of the strangest places in the solar system: Occator Crater.

Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.

Two NASA telescopes peered more closely than ever before at a planet shedding gas into space.

Ceres, the closest dwarf planet to Earth, may be wrinkling as it shrinks.

Haumea's ring is too faint to be seen from planet Earth, so astronomers have turned to context clues to find out more about these particles.

Nearly three years since NASA's Dawn mission arrived at Ceres, the spacecraft has run out of fuel. Is it time to start thinking about sending another mission to the dwarf planet?
