A ‘Warp’ In Our #SolarSystem Might Be an Undiscovered World: #PlanetY
In addition to #PlanetNine, the solar system may also contain a closer, smaller world that could be spotted soon.

Planet Nine was put forward in 2016 by Michael Brown and Konstantin Batygin of the California Institute of Technology to explain an unusual bunching of orbits of some objects in the #KuiperBelt, such as #Sedna.

A cousin for Pluto? New dwarf planet candidate found
Astrophysicists say they've identified an object beyond the orbit of Neptune that's likely to qualify as a dwarf planet, alongside other trans-Neptunian objects including Pluto, the erstwhile "ninth planet."

The discovery of 2017 OF201 touches upon another ninth-planet contr
