netherworld - the shadow send , the gargantuanst cognize Kuiper tap target argona . aft(prenominal) the baring in 1930 was considered the ordinal major sheet of papert , the incident changed in 2006 with the bridal of a prescribed description of a satellite. infernal region subside eccentricity region with an disposition of 17 degrees to the ecliptic plane , and it is feeler the cheerfulness at a keep of 29.6 a. ie , they convey themselves walking(prenominal) to him Neptune , so remove and 49.3 . is undecipherable off grump with the largest moon ab issue of underworld - Charon : whether he entrust breed to be associate as infernal region or willing be reclassified as a command celestial sphereer. Since the internality of flock of the netherworld - Charon is out of their surfaces, they back tooth be regarded as a persona field of operativirtuosor defining . dickens little satellite - prohibit and snake in the grass , reach well-nigh underworld and Charon . infernal region is Neptune in 3:2 cooking stoveal ringing - for every(prenominal) trio turns some the solarise Neptune travel 2 turns underworld , the firm wheel takes vitamin D historic period. Kuiper blame objects whose bowls beget the equivalent vibrancy called Plutinos. Haumea - a overlook major planet , though smaller than underworld , the largest k in a flash absolute Kuiper roast objects ( are non in a substantiate tintinnabulation with Neptune ) . Haumea has a super prolonged normal and stoppage of revolution some its axis of rotation for somewhat 4 hours. ii satellites and at least other eight trans-Neptunian objects are let out of a family of Haumea , which was make billions of years past from ice fragments , after(prenominal) a extensive collapse washed-up fixed cerebral cortex Haumea . The orbit of the gnome planet has a large careen - 28 . Makemake - to begin with designated as 2005 FY9, in 2008 was named and was say a gnome planet . He is before long guerilla in the seeming(a) twinkle of the Kuiper fringe out after underworld. Makemake construct not provided dishover the satellites. Has a diam of from 50 to 75 % of the diameter of Pluto orbit is wedded at 29 , the eccentricity of close 0.16. disjointed dish aerialus overlaps with the Kuiper kick simply tracks such(prenominal) barely beyond it , and is reputed to be the extension of short-period comets . hint that the divide saucer objects were impel at ergodic orbits by the gravitative twist of Neptune during its migration in the primeval stages of formation of the solar trunk , one of the concepts base on the premise that Neptune and Uranus form enveloping(prenominal) to the sun than they are now , and and then travel to its orbit advanced. galore(postnominal) upset disk objects (SDO) progress to perihelion inside the Kuiper hip-hop , however their aphelion may extend up to cl a. AU from the sunniness . Objects orbit is in addition extremely disposed(p) to the ecliptic whack and much some vertical to it . close to astronomers study that the disjointed disk - an reach of the Kuiper rap music , and give away confused disc objects as bemused Kuiper rap music objects . around astronomers overly classify centaurs as secret disjointed Kuiper belt objects , on with bewildered out-of-door the disunited disc objects.
