    This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...

    en.wikipedia.org/wiki/42355_Typhon

    Based on a conventional magnitude-to-diameter conversion, the body measures 162 km in diameter, with an albedo of 0.044 and a magnitude of 7.5. Mike Brown gives it a diameter of 192 km with a magnitude of 7.5. Due to its small size, it is unlikely to be classified as a dwarf planet. As of 2021, no rotational lightcurve has been analyzed.
