# The Upcoming Mutual Event Season for the Patroclus - Menoetius Trojan Binary

## TL;DR

This paper provides new observational data and orbital solutions for the binary Trojan asteroid Patroclus-Menoetius, predicting mutual events during 2017-2019 to aid NASA's Lucy mission planning.

## Contribution

It offers updated Keplerian orbit solutions and predicts mutual event timings for the Patroclus-Menoetius binary system.

## Key findings

- New Hubble and Keck observations of the binary system
- Updated orbital parameters for the Patroclus-Menoetius system
- Predicted mutual event times from 2017 to 2019

## Abstract

We present new Hubble Space Telescope and ground-based Keck observations and new Keplerian orbit solutions for the mutual orbit of binary Jupiter Trojan asteroid (617) Patroclus and Menoetius, targets of NASA's Lucy mission. We predict event times for the upcoming mutual event season, which is anticipated to run from late 2017 through mid 2019.
