Editing Clyde Tombaugh (section)

===Further research===
Tombaugh continued searching for over a decade after the discovery of Pluto, and the lack of further discoveries left him satisfied that no other object of a comparable [[apparent magnitude]] existed near the [[ecliptic]]. No more [[trans-Neptunian object]]s were discovered until [[15760 Albion]], in 1992.

However, in 2005 the relatively bright object {{dp|Makemake}} was discovered. It has a relatively high orbital [[inclination]], but at the time of Tombaugh's discovery of Pluto, Makemake was only a few degrees from the ecliptic, near the border of [[Taurus (constellation)|Taurus]] and [[Auriga (constellation)|Auriga]],<ref>based on Minor Planet Center online Minor Planet Ephemeris Service: March 1, 1930: RA: 05h51m, Dec: +29.0</ref> at an apparent magnitude of 16.<ref name=FY9>{{cite web|title=Horizons Web-Interface|publisher=[[JPL Solar System Dynamics]]|url=http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=2005FY9|access-date=July 1, 2008|archive-date=August 17, 2016|archive-url=https://web.archive.org/web/20160817003911/http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=2005FY9|url-status=live}}</ref> This position was also very near the [[galactic equator]], making it almost impossible to find such an object within the dense concentration of background stars of the [[Milky Way]].  In the fourteen years of looking for planets, until he was drafted in July 1943, Tombaugh looked for motion in 90 million star images (two each of 45 million stars).<ref>Tombaugh (1980:172)</ref>
