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.
Mercury is the smallest planet to go around the sun.
Venus.Mercury and Mars are smaller
mercury it was pluto but pluto has been considered as a "dwarf planet"

The only planet with one moon is Earth. The smallest planet is Mercury but it doesn't have any moons.
The moon itself is not considered a planet. It is Earth's only moon. Since Pluto is not considered a planet (as of 2006), the smallest planet in our solar system is Mercury.

The smaller and more distant a moon is, the harder it is to detect. The smallest moon so far discovered is Aegaeon, a moon of Saturn with a diameter of around half a kilometre.
The moon is the smallest out of the Sun,Earth and moon. It should be note, though, that neither the sun nor the moon are planets; the sun is a star and the moon is a natural satellite.
Mercury is the smallest. It's slightly bigger than the moon.
Titan is the largest moon of Saturn. The smallest of the eight planets is Mercury.
Pluto
One cannot say for sure if it is the smallest planet in space, but it is the smallest planet in our Solar System.
Mercury is the smallest planet except for pluto. It has a radius of 2439km.
