Answer:
Exoplanets would orbit their own stars instead of the Sun
Explanation:
Our solar system is defined by the planets and other celestial objects which orbit the sun, a star. Exoplanets do not orbit our sun, but are orbiting their own star.
Nothing would guarantee that any amount of exoplanets would have a moon.
The size of a planet is a defined term based on size, but it doesn't necessarily have to have a large mass to be a planet.
