# Meteorites from Phobos and Deimos at Earth?

## TL;DR

This paper investigates the potential for meteorites originating from the moons Phobos and Deimos to reach Earth, finding that ejection speeds required are feasible given typical impact velocities.

## Contribution

It demonstrates that meteorites from Phobos and Deimos can reach Earth due to their low ejection speed requirements, expanding understanding of extraterrestrial material sources.

## Key findings

- Ejection speeds from Phobos and Deimos are 900 and 600 m/s respectively.
- These speeds are below typical impact velocities at Mars' orbit.
- Meteorites from these moons can feasibly reach Earth.

## Abstract

We examine the conditions under which material from the martian moons Phobos and Deimos could reach our planet in the form of meteorites. We find that the necessary ejection speeds from these moons (900 and 600 m/s for Phobos and Deimos respectively) are much smaller than from Mars' surface (5000 m/s). These speeds are below typical impact speeds for asteroids and comets (10-40 km/s) at Mars' orbit, and we conclude that the delivery of meteorites from Phobos and Deimos to the Earth can occur.
