Before Pluto was reclassified as a dwarf planet, Mercury was the second smallest planet.The second smallest planet in the solar system is Mars with a diameter of 4,221.6 miles.Mars is the 2nd smallest planet, Mercury is the smallest.Mercury
Neither - Mercury is the smallest planet in our Solar System at 0.055 Earth masses and Jupiter is the largest planet in our Solar System at 318 Earth masses (e.g. which is 2.5 times the mass of all the other planets put together).
