2014 SV349 is a large trans-Neptunian object from the scattered disc located in the outermost region of the Solar System. The object is a dwarf planet candidate and measures approximately 423 kilometers (260 miles) in diameter. It was discovered on 19 September 2014, by American astronomer Scott Sheppard at the Cerro Tololo Observatory, Chile.[1]
Orbit and classification
This minor planet orbits the Sun at a distance of 35.0–88.4 AU once every 484 years and 10 months (177,075 days; semi-major axis of 61.71 AU). Its orbit has an eccentricity of 0.43 and an inclination of 18° with respect to the ecliptic.[3] 2014 SV349 is moving closer to the Sun and will come to perihelion in 2106.[3] As of 2025, it is at 59.1 AU from the Sun.[7]
It is classified as a scattered disc object,[4] or "near-scattered" object in the classification of the Deep Ecliptic Survey,[5] that still gravitationally interacts with Neptune (30.1 AU) due to its relatively low perihelion of 35.0 AU, contrary to the extended-scattered/detached objects and sednoids which never approach Neptune as close.
Physical characteristics
Based on a generic magnitude-to-diameter conversion, 2014 SV349 measures approximately 423 kilometers (260 miles) in diameter, for an assumed albedo of 0.9 and a magnitude of 5.1.[4][6]
