Do mirror planets exist in our solar system?

TL;DR

This paper explores the hypothesis that mirror matter, a theoretical form of matter predicted by physics, could exist in our solar system as unseen planetary or stellar bodies, and discusses potential observational evidence.

Contribution

It investigates the possibility of mirror matter bodies in the solar system and evaluates observable effects and detection prospects.

Findings

Long period comets suggest a possible unseen solar companion.

Mirror matter could explain the existence of hypothetical objects like Nemesis.

Potential observable effects could help detect mirror matter bodies in the solar system.

Abstract

Mirror matter is predicted to exist if parity is an unbroken symmetry of nature. Currently, there is a large amount of evidence that mirror matter actually exists coming from astrophysics and particle physics. One of the most fascinating (but speculative) possibilities is that there is a significant abundance of mirror matter within our solar system. If the mirror matter condensed to form a large body of planatary or stellar mass then there could be interesting observable effects. Indeed studies of long period comets suggest the existence of a solar companion which has escaped direct detection and is therefore a candidate for a mirror body. Nemesis, hypothetical "death star" companion of the Sun, proposed to explain biological mass extinctions, may potentially be a mirror star. We examine the prospects for detecting these objects if they do indeed exist and are made of mirror matter.
