In the search for the hypothetical Planet Nine, scientists may have uncovered another explanation for the patterns in the orbits of Kuiper Belt objects.
Whether you call it Planet X or Planet Nine, talk of another planet lurking in our Solar system won’t go away. So what does the discovery of a new object – nicknamed “The Goblin” – add to the debate?
Discovery of many icy worlds helps unravel the solar system’s history.
It turns out that a common physical process called diffusion can explain the orbits of faraway minor planets – no need for a Planet Nine.
Why Planet Nine should be found in the next few years … if it exists.
The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
