2015 FJ ₃₄₅ is a planetoid that was discovered on March 17, 2015 at Mauna Kea and belongs to the group of the Kuiper Belt planetoid. The asteroid will orbit the Sun in a moderately eccentric orbit in 503 years , so that it is in a 3: 1 orbit resonance with Neptune. The eccentricity of its orbit is 0.20, with it being inclined at 34.95 ° to the ecliptic .
