It was discovered on 11 November 2010, by American astronomers [[David L. Rabinowitz|David Rabinowitz]], [[Megan E. Schwamb|Megan Schwamb]] and [[Suzanne W. Tourtellotte|Suzanne Tourtellotte]] at ESO's [[La Silla Observatory]] site in northern Chile,<ref name="MPC-object" /> when it was 38&nbsp;[[Astronomical unit|AU]] from the Sun.

 

== Orbit and classification ==

{{mp|2010 VZ|98}} orbits the Sun at a distance of 34.3–266.6&nbsp;[[Astronomical unit|AU]] once every 1846 years (674,262 days; [[semi-major axis]] of 150.5&nbsp;AU). Its orbit has a high [[orbital eccentricity|eccentricity]] of 0.77 and an [[orbital inclination|inclination]] of 5[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> [[Small number statistics]] suggest that this body may be trapped in a 3:2 [[orbital resonance]] with an unseen [[planet beyond Neptune]] with a [[semi-major axis]] of 195–215&nbsp;AU.<ref name="Marcos-2014" /> The first [[precovery]] was taken by the [[Sloan Digital Sky Survey]] at the [[Apache Point Observatory]] in 1998, extending the body's [[observation arc]] by 12 years prior to its discovery. The precoveries were found in May 2015 ({{small|MPS 604632}}).<ref name="MPC-object" />

 

== Physical characteristics ==

A rotational [[lightcurve]] of {{mp|2010 VZ|98}} was obtained from [[Photometry (astronomy)|photometric]] observation by members of the [[Carnegie Institution for Science]] at [[Las Campanas Observatory]], Chile. The light-curve gave a [[rotation period]] of {{val|9.72|0.05}} hours with a brightness variation of 0.18 magnitude ({{small|[[LCDB quality code|U=n.a.]]}}).<ref name="Benecchi-2013" />

 

=== Diameter and albedo ===

While American astronomer [[Michael E. Brown]] assumes a diameter of 471 kilometers and an [[astronomical albedo|albedo]] of 0.07,<ref name="Brown-dplist" /> the ''Johnston{{'s}} Archive'' estimates a diameter of 443 kilometers with generic albedo of 0.09.<ref name="johnstonsarchive-TNO-list" /> The ''Collaborative Asteroid Lightcurve Link'' assumes an albedo of 0.10 and calculates a diameter of 401 kilometers.<ref name="lcdb" /> These estimates are based on an [[absolute magnitude]] between 5.0 and 5.3.<ref name="Brown-dplist" /><ref name="lcdb" />

 

== Naming ==

As of 2018, this [[minor planet]] remains unnamed.<ref name="MPC-object" />
