Neptunoren troiar
Neptuno planetaren orbita bera duen asteroideetako bakoitza; orbitaren Lagrangeren puntuetan kokatzen direnez, ez dute planetarekin talka egingo
Neptunoren troiarrak[1] (Jupiterren troiarrekin duten analogiaz horrela deituak) bere orbita Neptunorekin partekatzen duten asteroideak dira, betiere, L4 eta L5 izeneko Lagrangeren puntu egonkorren inguruan.[2] Neptunoren Lagrangeren puntu egonkorretatik gertu orbitatzen dira.
Hona hemen IAUren Minor Planet Centerrek onarturiko Neptunoren troiarrak:[3]
