In the race to discover a proposed ninth planet in our solar system, astronomers are conducting the largest, deepest survey for objects beyond Neptune and the Kuiper Belt. Nearly 10 percent of the sky has been explored to date using some of the largest and most advanced telescopes, revealing several never-before-seen objects at extreme distances from the Sun.

The search for distant solar system objects has found two more small worlds far outside the orbit of Neptune, beyond the Kuiper Belt. The new objects, 2014 FZ71 and 2015 FJ345, are in resonance with Neptune’s orbit, implying that these worlds either have interacted with Neptune in the past or are continuing to do so.
