Why does Triton orbit opposite of Neptune?
Why does Triton orbit opposite of Neptune?
At some point in Neptune’s early history, Triton’s orbit around the Sun may have carried it too near the giant planet. Gas drag in Neptune’s extended atmosphere or a collision with an existing moon of Neptune slowed Triton enough to place it in an elongated orbit, which was also retrograde and highly inclined.
Why do Neptune’s moons have weird orbits?
Orbital resonance Astronomers have found many examples of orbital resonances in the solar system. Pluto and Neptune are in a resonance in which Pluto orbits the Sun twice for every three times that Neptune does. This resonance keeps the two objects’ orbits stable.
Why is Triton spiraling in toward Neptune?
In fact, Triton is thought to have been captured from the Kuiper Belt some time in the past, and it is very much like what Pluto must be like–largely made of ices. Because it orbits retrograde, it is slowly spiralling toward Neptune due to tidal interactions.
How does Triton Neptune’s moons orbit?
Triton is the biggest of Neptune’s thirteen known moons. This moon is suspected to have been captured by Neptune, which would explain its highly unusual orbit and rotation. One of the only bodies in the solar system to have a retrograde orbit, Triton also rotates at an angle of 157° to the axis of Neptune’s rotation.
What is different about the orbit of Triton around Neptune compared to other big moons around their planets What does this tell us about how Triton became a moon?
Triton is unique among all large moons in the Solar System for its retrograde orbit around its planet (i.e. it orbits in a direction opposite to the planet’s rotation). Most of the outer irregular moons of Jupiter and Saturn also have retrograde orbits, as do some of Uranus’s outer moons.
Does Triton rotate clockwise or counterclockwise?
But unlike the earth’s moon and most other solarsystem satellites, Triton moves in a retrograde direction: it circles the “wrong” way—clockwise—around Neptune which spins counterclockwise on its axis.
How is Triton Unique among the moons of the outer solar system?
Triton is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune’s gravity millions of years ago.
How does Neptune rotate?
Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the Sun, which is similar to the axial tilts of Mars and Earth. This means that Neptune experiences seasons just like we do on Earth; however, since its year is so long, each of the four seasons lasts for over 40 years.
What is unusual about Neptune’s moon Triton relative to other moons quizlet?
What is unusual about Triton? It orbits its planet backward. Only one of the moons of the jovian planets has an atmosphere thicker than Earth’s atmosphere.
Does Neptune orbit backwards?
Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet’s rotation. It is the only large moon in the Solar System to do this. Astronomers are not quite sure of the reason for this retrograde orbit.
What is the orbit of Triton around Neptune?

What is unique about Neptune’s moon Triton compared to all other large moons in the solar system?
Orbit and rotation Triton is unique among all large moons in the Solar System for its retrograde orbit around its planet (i.e. it orbits in a direction opposite to the planet’s rotation).
