Astrophysics Quote by Neil deGrasse Tyson

“Newton's laws specifically state that, while the gravity of a planet gets weaker and weaker the farthest from it you travel, there is no distance where the force of gravity reaches zero.

““Newton's laws specifically state that, while the gravity of a planet gets weaker and weaker the farthest from it you travel, there is no distance where the force of gravity reaches zero. The planet Jupiter, with its mighty gravitational field, bats out of harm's way many comets that would otherwise wreak havoc on the inner solar system. Jupiter acts as a gravitational shield for Earth, a burly big brother, allowing long (hundred-million-year) stretches of relative peace and quiet on Earth. Without Jupiter's protection, complex life would have a hard time becoming interestingly complex, always living at risk of extinction from a devastating impact.””
