No force is necessary to keep a moving object in motion. But if you want it to
follow a curve, such as for example a closed orbit, then that takes force. The
force that keeps Neptune in its closed orbit is the same force that keeps every
planet, moon, comet, and asteroid in its own closed orbit around its own central
body. It's the force of gravity.
What else can I help you with?
What word is used to describe the motion of Neptune's biggest moon trion?
The motion of Neptune's biggest moon, Triton, is described as "retrograde." This means that Triton orbits Neptune in the opposite direction to the planet's rotation. This unusual motion suggests that Triton may have been captured by Neptune's gravity rather than forming in place, as most moons do.
What does the retrograde motion of neptune's moon Triton indicate about its origin?
Because Triton revolves around Neptune opposite its rotational direction it is considered retrograde. This indicates that it was likely a planetoid that was captured by Neptune's gravity rather than having formed in orbit around Neptune.
What allow Jupiter Saturn Uranus and Neptune to keep most of the gasses in their atmosphere?
gravity
What is Neptune gravity?
Neptune has a surface gravity of 11.15m/s2 or 1.14g.
What is the percentage of the gravity of Neptune compared to Earth?
Neptune has a gravity that is about 1.14 that of Earth.
What is the planet Neptune's gravity?
It is estimated that the gravity on Neptune is 12% greater than Earth
Is there more or less gravity on Neptune then on earth?
Neptune has slightly more gravity than Earth. It is believed that the gravity is 17% greater than Earth's.
What two motions act upon a satellite to keep it in motion?
Gravity and inertia.
Surface gravity of Neptune?
Neptune's gravity is 1.14 times the earths gravity. So if you weigh 100 pounds you would weigh 114 on Neptune.
What is name force that keep earth certain distance from sun?
Gravity - combined with the Earth's inertia (its mass, and Newton's laws of motion).Gravity - combined with the Earth's inertia (its mass, and Newton's laws of motion).Gravity - combined with the Earth's inertia (its mass, and Newton's laws of motion).Gravity - combined with the Earth's inertia (its mass, and Newton's laws of motion).
Is there gravity on Neptune?
yes there is.
Has Neptune got stronger or weaker gravity than Earth?
Neptune's gravity is stronger, and is equal to 11m/s2.
