2006 JY26 is a near-Earth object that is also horseshoe companion to the Earth like 3753 Cruithne.[5]
Discovery, orbit and physical properties
[edit]2006 JY26 was discovered by E. J. Christensen on 6 May 2006, observing for the Catalina Sky Survey.[6][7]
Its orbit is characterized by low eccentricity (0.083), low inclination (1.44º) and a semi-major axis of 1.01

It is listed on the Sentry Risk Table with a 1 in 210 chance of impacting Earth on 3 May 2074.[9][11] The nominal best-fit orbit shows that 2006 JY26 will be 0.0099
Horseshoe companion to the Earth and orbital evolution
[edit]Recent calculations indicate that it follows a horseshoe orbit with respect to the Earth.[5] It had a close encounter with the Earth on 10 May 2006, at 0.0029
Origin
[edit]It may have been originated within the Venus–Earth–Mars region or in the main asteroid belt like other near-Earth objects, then transition to Amor-class asteroid before entering Earth's co-orbital region.[5]
