why planet nine may not actually exist

Astronomers looking into the orbits of Kuiper Belt objects may have found a flaw in data we thought pointed to the existence of a large planet beyond Neptune’s orbit.

a planet four times the size of its star shows how solar systems die

When some stars die, they take their entire systems with them. Others appear to give their planets a fighting chance.

A recent paper imagines a new explanation for the strange motions of Trans-Neptunian Objects observed by astronomers for the last 200 years, but it doesn’t mean that we won’t still search for Planet Nine.

A massive collision seems to be the only plausible reason why Uranus is the oddball it is, and now we have an idea of what it might have looked like. So what do we do with this data?
