Although Pluto is located far from the Sun, it still remains in orbit due to the gravitational force acting between them. The force of gravity is determined by the masses of the objects involved and the distance between them. While the gravitational force between Pluto and the Sun is weaker compared to objects closer to the Sun, it is still sufficient to maintain Pluto's orbit.
Pluto's orbit around the Sun is governed by the laws of celestial mechanics, particularly Isaac Newton's law of universal gravitation and his laws of motion. According to these laws, the gravitational force between two objects decreases with the square of the distance between them. So, even though Pluto is far from the Sun, the Sun's tremendous mass ensures that it exerts a gravitational pull on Pluto.
Pluto's relatively low mass means it experiences a weaker gravitational force compared to larger planets like Earth or Jupiter. However, this gravitational force is enough to keep Pluto in a stable orbit around the Sun. The precise balance between the gravitational force and Pluto's centripetal force—the force that keeps it in a curved path—is what maintains its orbit.
It's worth noting that the concept of "escape velocity" comes into play when considering whether an object can break free from the gravitational pull of a celestial body. Escape velocity is the minimum velocity an object needs to escape the gravitational pull of a particular body. For Pluto to escape the Sun's gravitational pull entirely, it would need to reach an extremely high velocity, which is not attainable under its current conditions.
Therefore, while the gravitational force between Pluto and the Sun is relatively small compared to closer objects, it is still significant enough to keep Pluto in orbit and prevent it from escaping the Sun's gravitational influence.
