2014 FC69 is a trans-Neptunian object of the scattered disc on an eccentric orbit in the outermost region of the Solar System . It was first observed on 25 March 2014, by American astronomers Scott Sheppard and Chad Trujillo at the Cerro Tololo Observatory in Chile.[1] It is one of the most distant objects from the Sun , even further away than Sedna .
Orbit and classification
[ edit ]
As of 2021[update] and based on an orbital uncertainty of 6–7 and an observation arc of only 682 days, 2014 FC69 orbits the Sun at a distance of 40.1–104.2 AU once every 612 years and 10 months (223,847 days; semi-major axis of 72.15 AU ). Its orbit has an eccentricity of 0.44 and an inclination of 30° with respect to the ecliptic .[2]
Based on the best-fit (albeit uncertain) orbital solution, 2014 FC69 is a scattered disc object ,[4] or "near-scattered" in the classification of the Deep Ecliptic Survey ,[5] that still interacts gravitationally with Neptune due to its relatively low perihelion of 40.1 AU, contrary to the extended-scattered/detached objects and sednoids which never approach Neptune as close as 2014 FC69 does.
Most distant objects from the Sun
[ edit ]
2014 FC69 last came to perihelion around 1865,[2] moving away from the Sun ever since and is currently about 85.6 AU from the Sun,[8] which is further away than the dwarf planet Sedna . Other than long-period comets , it is the 10th-most-distant known larger body in the Solar System (also see List of Solar System objects most distant from the Sun § Known distant objects ) .[9]
Physical characteristics
[ edit ]
Based on a generic magnitude-to-diameter conversion from its magnitude of 4.6, 2014 FC69 is approximately 533 kilometers (330 miles) in diameter, assuming an albedo of 0.9.[4] [7]
As of 2021[update] , no rotational lightcurve for this object has been obtained from photometric observations. The body's rotation period , pole and shape remain unknown.[2]
