We significantly constrain the sky position, distance, and mass of a possible additional, distant planet in the solar system by examining its influence on the distance between Earth and the Cassini Spacecraft. Our preferred region is approximately centered on (RA, Dec) = ($40\arcdeg$, $-15\arcdeg$), extending approximately 20 degrees in all directions.

A Solar-System Window for Hidden Stellar Companions
The paper builds an illustrative mass-distance window for hidden-brane companions and finds overlap with the minimum mass of a QCD-scaled hidden star at the upper end of the allowed range.
