Sednoid
A sednoid is a trans-Neptunian object with a perihelion greater than 50 AU and a semi-major axis greater than 150 AU . [1] [2] Only three objects are known from this population, 90377 Sedna , 2012 VP 113 , and 2015 TG 387 , all of which have perihelia greater than 64 AU , [3] but it is suspected that there are many more. These objects lie outside an apparently nearly empty gap in the Solar System starting at about 50 AU, and have no significant interaction with the planets. They are usually grouped with the detached objects . Some astronomers, such as Scott Sheppard, [4] consider the sednoids to be inner Oort cloud objects (OCOs), though the inner Oort cloud , or Hills cloud, was originally predicted to lie beyond 2,000 AU, beyond the aphelia of the three known sednoids.

A sednoid is a trans-Neptunian object with a perihelion greater than 50 AU and a semi-major axis greater than 150 AU . [1] [2] Only two objects are known from this population, 90377 Sedna and 2012 VP 113 , both of which have perihelia greater than 75 AU , [3] but it is suspected that there are many more. These objects lie outside an apparently nearly empty gap in the Solar System starting at about 50 AU, and have no significant interaction with the planets. They are usually grouped with the detached objects . Some astronomers, such as Scott Sheppard, [4] consider the sednoids to be inner Oort cloud objects (OCOs), though the inner Oort cloud , or Hills cloud, was originally predicted to lie beyond 2,000 AU, several times as far as the aphelia of the two known sednoids. |
