Size is not the differentiation of whether something is a planet or moon. The difference is what ir orbits. A planet orbits a star, and only a star. A moon orbits a planet. A moon is always smaller than the planet it belongs to, but some large moons are bigger than small planets. Ganymede and Titan are both larger than the planet Mercury, but are still much smaller than than planets they orbit, Jupiter and Saturn.
Venus is only slightly smaller than Earth.
