Currently, Mercury. Used to be Pluto, R.I.P. Pluto :(
Venus.Mercury and Mars are smaller
Pluto was the smallest but is no longer classed as a planet, it is now a dwarf planet, so going by that, Mercury is now the smallest, followed by Mars, so it would be Mars.
Neither. Titan is the largest moon of Saturn but the second largest in the solar system. The largest moon in the solar system is Ganymede, which orbits Jupiter.
Pluto is no longer considered a planet by the International Astronomical Union; it is classified as a dwarf planet. Among the eight recognized planets in our solar system, Mercury is actually the smallest.
Starting from least to greatest magnitude in size: Earth Sun Solar System Milky Way Galaxy Universe
