Prospects for unseen planets beyond Neptune
Renu Malhotra

TL;DR
This paper reviews the evidence and theoretical considerations for the possible existence of unseen large planets beyond Neptune, which could explain anomalies in Kuiper Belt object distributions.
Contribution
It provides a comprehensive review of the current evidence and theoretical models suggesting unseen planets in the distant solar system.
Findings
Anomalous Kuiper Belt object distributions may indicate unseen planets.
Theoretical models support the possibility of large bodies beyond Neptune.
Further observational efforts are needed to confirm these planets.
Abstract
Several anomalous features in the orbital distribution of distant Kuiper Belt objects have recently sparked suggestions of an unseen large planet (or two) orbiting beyond Neptune. I review the theoretical arguments and the prospects for the existence of unseen massive bodies in the distant solar system.
