The smallest planet in our solar system is Mercury. It's the smallest known planet in our galaxy, since we would not be able to see one that small in any other far off systems. smaller planets could exist, would they still have to fulfil the same criteria? Ceres, a dwarf planet is only 900km in diameter. This is about the limit, much smaller than this and the planet would struggle to hold a spherical shape.
