Why voyager1 is not bound to the Sun despite being closer thatn the oort Cloud comets?

Question

Voyage 1 is a spacecraft that is approximately 100 AU from the Sun. Many comets in the Oort Cloud reside at 1000 AU or more from the sun. the Ooct Cloud comets are bound to the Sun, but voyage 1 is not. Explain Why voyager1 is not bound to the Sun despite being closer thatn the oort Cloud comets.

Answer 1

Its because Voyager is going at a very fast speed; faster than most comets in the Oort Cloud; The Oort Cloud is farther from the sun, thus making its hold on coments and such weaker; Voyager had to endure the sun's gravity for the 1st beginning of the trip because it came from Earth; which is closer to the sun that the Oort Cloud.

Answer 2

speed is the key here. The Oort cloud objects are bound to the sun because their speed isn't enough to overcome the gravitational force exerted by the sun.

Voyager, on the other hand, is moving at 40 miles a second, fast enough such that the sun's pull isn't enough to keep it trapped in orbit.

Answer 3

Because it is leaving at a speed higher than escape velocity. Eventually Voyager will be 1,000 AU away, then 10,000, then a million. It will never stop.

Answer 4

Probably because of its speed. It is travelling at about 17km/s. This is much more than solar escape velocity at that distance (4.1km/s) so we know it will escape. It is slowing down a bit, but never fear, its off to the stars with its message from earth.
