An exoplanet system consists of a massive central exoplanet, a regular moon, and an incoming captured asteroid.
Name the attractive force that keeps both the regular moon and the captured asteroid in stable or semi-stable orbits around the exoplanet.
The simplified schematic below shows the orbits of the regular moon and the captured asteroid around the exoplanet.
Identify which label (JJJ, KKK, or LLL) represents the exoplanet, the regular moon, and the captured asteroid. Briefly justify each choice.
Explain why it is physically possible for the regular moon and the captured asteroid to eventually collide.
