This astronomy illustration shows relative sizes of the Solar System planets.
"A planetary system is a set of gravitationally bound non-stellar objects in orbit around a star or star system. Generally speaking, planetary systems describe systems with one or more planets, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets and planetesimals as well as discernable features including circumstellar disks. The Sun together with its planetary system, which includes Earth, is known as the Solar System." [Planetary system. Wikipedia]
