Gravity Holds Solar System Practice Test

Two models compare a moon orbiting a planet and a planet orbiting the Sun. In both models, the central object is labeled larger mass, the orbiting object is labeled smaller mass, gravity arrows point toward the central object, and a velocity arrow shows the orbiting object’s motion.

Which claim is best supported by these models about why objects remain bound in the solar system?

A model shows the Sun (labeled larger mass) and a comet (labeled smaller mass) moving past the Sun. The comet has a long velocity arrow showing fast motion. Gravity arrows point from the comet toward the Sun, showing attraction at a distance.

Which conclusion is best supported by the model about whether the comet stays bound to the solar system?
