{{#invoke:Infobox|infobox}} (177049) 2003 EE16, provisionally known as 2003 EE16, is a near-Earth asteroid and potentially hazardous object.<ref name=jpldata/> It was discovered on 8 March 2003 by LPL/Spacewatch II at an apparent magnitude of 20 using a {{safesubst:#invoke:convert|convert}} reflecting telescope.<ref name="MPEC2003-E34"/> It has an estimated diameter of {{safesubst:#invoke:convert|convert}}.<ref name="Wayback2003-04"/> The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 2 April 2003.<ref name="Wayback2003-04"/>

Many of the virtual impactors were located near the nominal orbital solution and the asteroid has a low inclination relative to Earth's orbit.<ref name="spaceguard"/> Observation by the Very Large Telescope (VLT) 8 meter facilities on 22 May and 19 June 2003 when 2003 EE16 was very dim with an apparent magnitude between 24–25<ref group="note">At an apparent magnitude of 24, the asteroid was roughly 10 million times fainter than can be seen with the naked eye.
Math: <math>(\sqrt[5]{100})^{24-6.5}\approx 10000000</math></ref> refined the orbit.<ref name="spaceguard"/> It was removed from the Sentry Risk Table on 28 May 2003.<ref name="removed"/>

2003 EE16 has the smallest Earth Minimum orbit intersection distance (MOID) of any known potentially hazardous asteroid.<ref name="jpl-search"/> The Earth MOID is {{safesubst:#invoke:convert|convert}}.<ref name="jpl-search"/> Asteroids with a smaller Earth MOID are less than ~100 meters in diameter such as 2013 XY8 and 2010 TD54. Earth impactors 2008 TC3 and 2014 AA had small Earth MOID values as they were on their impact approach when discovered.
