'''{{mp|(527603) 2007 VJ|305}}''' ([[provisional designation]] '''{{mp|2007 VJ|305}}''') 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 {{convert|250|km|mi|abbr=off|sigfig=2|sp=us}} in diameter and is [[List of possible dwarf planets|"possibly" a dwarf planet]]. The rather reddish [[extended scattered disc object]] belongs to the group of extreme trans-Neptunian objects. It was discovered on 4 November 2007 by astronomers [[Andrew C. Becker|Andrew Becker]], [[Andrew W. Puckett|Andrew Puckett]] and [[Jeremy Martin Kubica|Jeremy Kubica]] at the [[Apache Point Observatory]] in New Mexico, United States.<ref name="MPC-object" /><ref name="MPC-CEN-SDO-list" />

== Orbit and classification ==

== Orbit and classification ==

{{mp|2007 VJ|305}} orbits the Sun at a distance of 35.1–347&nbsp;[[Astronomical unit|AU]] once every 2640 years and 11 months (964,601 days; [[semi-major axis]] of 191.1&nbsp;AU). Its orbit has an exceptionally high [[orbital eccentricity|eccentricity]] of 0.82 and an [[orbital inclination|inclination]] of 12[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> The body's [[observation arc]] begins with a [[precovery]] taken during the [[Sloan Digital Sky Survey]] at [[Apache Point Observatory|Apache Point]] in November 2000.<ref name="MPC-object" /> It has a [[minimum orbital intersection distance]] with [[Neptune]] of 5.4 AU.<ref name="MPC-object" />

It belongs to a small group of [[detached object]]s with perihelion distances of 30&nbsp;AU or more, and semi-major axes of 150&nbsp;AU or more.<ref name="MPC-query-ETNO" /> These extreme trans-Neptunian objects (ETNOs) can not reach such orbits without some perturbing object, which leads to the speculation of [[Planet Nine]].
