Someone needs another definition for ‘moon.’ Phil Plait on 2014 OL339:
…a 150-meter (or so) diameter rock discovered serendipitously in July by a team of asteroid hunters. Its orbit is highly elliptical; it crosses the orbit of Venus and gets out as far as Mars. It’s also slightly tilted compared with the Earth’s orbit by about 10… the numbers work out such that it takes—get this—364.92 days to circle the Sun once. Sound familiar? That’s only a few hours less than the Earth’s orbital period (one year, of course). When two objects orbit with periods very close to the same number (or simple multiples, like one taking exactly twice as long as the other) we say they are in resonant orbits.
So, it’s not earth’s new moon?
