In 2006 (yes, it was that long ago - yikes) the International Astronomical Union (IAU) officially adopted the definition of dwarf planet - they are large enough for their gravity to pull themselves into a sphere, they orbit the sun and not another larger body, but they don't gravitationally dominate their orbit. That last criterion

On the 91st Martian day, or sol, of NASA’s Mars 2020 Perseverance rover mission, the Ingenuity Mars Helicopter performed its sixth flight. The flight was designed to expand the flight envelope and demonstrate aerial-imaging capabilities by taking stereo images of a region of interest to the west. Ingenuity was commanded to climb to an altitude of 33 feet (10 meters) before translating 492 feet (150 meters) to the southwest at a ground speed of 9 mph (4 meters per second). At that point, it was to translate 49 feet (15 meters) to the south while taking images toward the west, then fly another 164 feet (50 meters) northeast and land.
