2013 FS28 is an extreme trans-Neptunian object from the extended scattered disc on a highly eccentric orbit in the outermost region of the Solar System. It measures approximately 466 kilometers (290 miles) in diameter. The detached, extended scattered disc object belongs to the group of extreme trans-Neptunian objects. It was first observed on 16 March 2013, by American astronomers Scott Sheppard and Chad Trujillo at the Cerro Tololo Observatory in Chile.[3][1][2]
Orbit and classification
[edit]2013 FS28 is 83
It belongs to a small group of detached objects with perihelion distances of 30
Numbering and naming
[edit]As of 2018, this minor planet has neither been numbered nor named by the Minor Planet Center. The official discoverer(s) will be defined when the object is numbered.[1]
Physical characteristics
[edit]According to the Johnston's archive and to American astronomer Michael Brown, 2013 FS28 measures 464 and 468 kilometers in diameter based on an assumed albedo of 0.09 and 0.07, respectively.[5][7] As of 2018, no rotational lightcurve of has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[4][9]
