WT1190F (UDA34A3 or UW8551D) is a possible object orbiting the Earth that has not positively been identified with any other satellite (as far as I am aware). It was first discovered on February 18, 2013, and again on November 29, 2013, and most recently on October 3, 2015. The linkage was only made in 2015, however.

its orbit brings it from slightly within synchronous orbit to beyond the orbit of the Moon, nearly twice its orbit. Its inclination is only 3 degrees, suggesting it may have come from orbit of the Earth. Due to its dimness, it is likely very small, less than 3 meters or so.

I will look at its current orbit tomorrow, and see what information I can gain from this. After some not-so-extensive research I still can't seem to find any object that fits with this one's orbit, but either way it seems an interesting one and could very likely be a temporary moon of Earth
