Physical characteristicsThe size of {{mp|2002 XV|93}} has been measured by the Herschel Space Telescope to be 549.2{{±|21.7|23.0}} km.[6] It is likely a dwarf planet.[7] References1. ^{{Cite web|url=http://www.minorplanetcenter.org/iau/lists/TNOs.html|title=List Of Transneptunian Objects|accessdate=2010-10-27|publisher=IAU Minor Planet Center| archiveurl= https://archive.is/20101027133511/http://www.minorplanetcenter.org/iau/lists/TNOs.html| archivedate= 27 October 2010 | deadurl= no}} 2. ^1 2 {{Cite web |date=2010-07-27 |title=MPEC 2010-O39 :Distant Minor Planets (12 August 2010.0 TT) |publisher=Minor Planet Center & Tamkin Foundation Computer Network |url=http://www.minorplanetcenter.org/mpec/K10/K10O39.html |accessdate=2010-08-07| archiveurl= https://www.webcitation.org/67niL9ZA8?url=http://www.minorplanetcenter.org/mpec/K10/K10O39.html| archivedate= 20 May 2012 | deadurl= no}} 3. ^1 2 {{Cite web |type=2008-10-23 last obs |title=JPL Small-Body Database Browser: 2002 XV93 |url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2002XV93 |accessdate=30 March 2016}} 4. ^{{Cite web |title=AstDys 2002XV93 Ephemerides |publisher=Department of Mathematics, University of Pisa, Italy |url=http://hamilton.dm.unipi.it/astdys/index.php?pc=1.1.0&n=2002XV93 |accessdate=2010-08-07}} 5. ^{{Cite web |url=http://www.physics.nau.edu/~tegler/research/survey.htm |title=Kuiper Belt Object Magnitudes and Surface Colors |accessdate=2009-12-30 |last=Tegler |first=Stephen C. |date=2007-02-01 |archive-url=https://web.archive.org/web/20060901063349/http://www.physics.nau.edu/~tegler/research/survey.htm |archive-date=1 September 2006 |dead-url=yes |df=dmy-all }} 6. ^1 2 3 4 5 {{Cite journal | last1 = Mommert | first1 = Michael| last2 = Harris | first2 = A.
