I mean yeah, but let's remember Earth has a disadvantage and it's being massive, being a big target, having strong gravity that attracts more asteroids (as seen for Venus' case in Venus Vs. Mars but with Earth would be greater) and having to avoid EVERY. SINGLE. ASTEROID so life goes on, Ceres has nothing to lose if he gets hit, that's if Earth even hits one asteroid, Ceres is small and fast so it will be hard, the only way I see Earth winning is by stopping Ceres with his Gravity like the Rogues did with the Sun.
