Stepwise illustration of the orbits of a planet (e.g. Jupiter, blue) and an asteroid in 3:2 mean motion resonance with the planet (e.g. Hilda, pink). The planet's Lagrange points number 3, 4 and 5 are indicated. During successive orbits the asteroid passes through or near the planet's L5, L4, L3, L5, L4, L3, etc. For more details see Hilda family.
