Scott S. Sheppard in the context of Outer Solar System

2018 AG₃₇ is a distant trans-Neptunian object and centaur that was discovered 132.2 ± 1.5 AU (19.78 ± 0.22 billion km) from the Sun, farther than any other currently observable known object in the Solar System. Imaged in January 2018 during a search for the hypothetical Planet Nine, the confirmation of this object was announced in a press release in February 2021 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo. The object was nicknamed "FarFarOut" to emphasize its distance from the Sun.2018 AG₃₇ was discovered when it was near aphelion, the farthest point from the Sun in its elliptical orbit. The object is estimated to be at least 400 km (250 mi) in diameter. Because of its extreme distance, 2018 AG₃₇ appears extremely faint with an apparent magnitude of 25—only visible to the largest telescopes in the world.

2012 VP₁₁₃ is a trans-Neptunian object (TNO) orbiting the Sun on an extremely wide elliptical orbit. It is classified as a sednoid because its orbit never comes closer than 80.5 AU (12.04 billion km; 7.48 billion mi) from the Sun, which is far enough away from the giant planets that their gravitational influence cannot affect the object's orbit noticeably. It was discovered on 5 November 2012 at Cerro Tololo Inter-American Observatory in Chile, by American astronomers Scott Sheppard and Chad Trujillo, who nicknamed the object "Biden" because of its "VP" abbreviation. The discovery was announced on 26 March 2014. The object's diameter has not been measured, but its brightness suggests it is around 450 km (280 mi) in diameter. 2012 VP₁₁₃ has a reddish color similar to many other TNOs.

2012 VP₁₁₃ has not yet been imaged by high-resolution telescopes, so it has no known moons. The Hubble Space Telescope is planned to image 2012 VP₁₁₃ in 2026, which should determine if it has significantly sized moons.

2021 PH₂₇ is a kilometer-sized Atira-type near-Earth asteroid orbiting very close to the Sun. It was discovered by Scott Sheppard using the Dark Energy Camera (DECam) at Cerro Tololo Inter-American Observatory on 13 August 2021. 2021 PH₂₇ has the smallest semi-major axis and shortest orbital period among all known asteroids as of 2026, with a velocity at perihelion of 106 km/s (240,000 mph). It also has the largest relativistic perihelion shift of any known object orbiting the Sun, 1.6 times that of Mercury. 2021 PH₂₇ shares an identical orbit and color as 2025 GN1, which has led astronomers to believe that the two asteroids split apart from a parent body over 10,500 years ago.

Gridr (Saturn LIV), originally known as S/2004 S 20, is a natural satellite of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, and Jan Kleyna on October 7, 2019 from observations taken between December 12, 2004 and March 22, 2007. It was given its permanent designation in June 2021. On 24 August 2022, it was officially named after Gríðr, a jötunn in Norse mythology. She is the mother of Víðarr the silent and the consort of Odin. She warned Thor about the treachery of Geirröðr and equipped him with her belt of strength, her iron glove, and her staff Gríðarvöl (Gríðr's-staff).

Gridr is about 4 kilometres in diameter, and orbits Saturn at an average distance of 19.418 million km in 1010.55 days, at an inclination of 163° to the ecliptic, in a retrograde direction and with an eccentricity of 0.197.
