スコット・S・シェパード/list Discoveries
Sheppard was the lead discoverer of the object with the most distant orbit known in the Solar System, 2012 VP (nicknamed Biden). In 2014, the similarity of the orbit of 2012 VP to other extreme Kuiper belt object orbits led Sheppard and Trujillo to propose that an unknown Super-Earth mass planet (2–15 Earth masses) in the outermost Solar System beyond 200 AU and up to 1500 AU is shepherding these smaller bodies into similar orbits (see Planet X or Planet Nine). The extreme trans-Neptunian objects 2013 FT and 2014 SR, announced in 2016 and co-discovered by Sheppard, further show a likely unknown massive planet exists beyond a few hundred AU in the Solar System, with 2013 FT being the first known high semi-major axis and high perihelion object anti-aligned with the other known extreme objects. In 2018, the announcement of the high perihelion inner Oort cloud object 541132 Leleākūhonua (nicknamed "The Goblin") by Sheppard et al., being only the third known after 2012 VP and Sedna, further demonstrated that a super-Earth planet in the distant solar system likely exists as Leleākūhonua has many orbital similarities as the two other known inner Oort cloud objects.
Sheppard has been involved in the discovery of many small Solar System bodies such as trans-Neptunian objects, centaurs, comets and near-Earth objects.
Three comets are named after him which are Sheppard-Trujillo (C/2014 F3), Sheppard-Tholen (C/2015 T5) and comet Trujillo-Sheppard (P/2018 V5).
The possible dwarf planets discovered by Sheppard are 471143 Dziewanna, 2010 KZ, 2010 FX, 2013 FY, (523671) 2013 FZ and 2015 KH.
In 2018, Sheppard was the lead discoverer of the most distant observed object in our solar system and first object observed beyond 100 AU, dwarf planet 2018 VG (nicknamed Farout), which is around 120 AU from the Sun.
He discovered a minor-planet moon around likely dwarf planet 2013 FY.
He is also a co-discoverer of a minor-planet moon orbiting the binary trans-Neptunian object 341520 Mors–Somnus.
Among the numerous irregular moons of the major planets in whose discovery he has been involved are:
