WebIt is possible to have a gravitationally bound system where the masses do not “fall together,” but maintain an orbital motion about each other. We have one important final observation. Earlier we stated that if the total energy is zero or greater, the object escapes. Strictly speaking, (Figure) and (Figure) apply for point objects. WebFeb 26, 2024 · The stars of the Pleiades are gravitationally bound. As such, they move through space as a cohesive group, at roughly the same speed and in roughly the same direction, so their relative positions remain stable. The effect is like multiple lanes of traffic all moving together at the speed limit. biobuster near me
