The orbit of Triton is what's known as a retrograde orbit. This means that the moon orbits in the complete opposite direction of the planet's rotation. Triton is the only large moon discovered in our solar system so far that does this.
Scientists and astronomers are not sure why this happens.
One theory is that the moon condensed this way from original material in the early solar system.
Another theory, and the most widely accepted theory, is that Triton was not originally a moon of Neptune, that it was formed elsewhere and was captured by Neptune's gravity. As a matter of fact, the surface features of Triton and the size of Triton are very similar to the dwarf planet Pluto. From time to time, Pluto does cross Neptune's path of orbit, so it is very likely that Triton was either a dwarf planet itself or a moon of Pluto before Neptune's gravity forced it to switch orbits.
Triton has retrograde motion because it likely originated as a captured object from the Kuiper Belt, a region beyond Neptune. Captured moons often exhibit retrograde orbits due to the complex gravitational interactions between the moon, the planet, and other celestial bodies.
First, the question should say "Uranus and Venus". By "opposite" we mean opposite to the direction off all the other planets.
In the case of Uranus it is probably a result of massive impacts that changed its spin axis direction.
For Venus it may also be something to do with collisions. Alternatively there
are theories suggesting it may have something to do with the action of the extremely dense Venus atmosphere.

1) it doesn't really ... it's tilted about 90 degrees, so it spins on its side.
2) A planet's "spin" is the result of ALL the various collisions in the lifetime of the planet ... thus its random.
Any time that a moon orbits in the opposite direction of the planet's rotation and the orbits of its other moons, it is likely that the moon did not form when the planet did but instead was passing the planet when it got captured by its gravity.
Triton has a retrograde orbit because it was captured rather than formed. It is thought that it was a dwarf planet in the Kuiper belt before being captured by Neptune.

What is Triton orbital period?
Triton, the largest moon of Neptune, has an orbital period of about 5.9 Earth days. It orbits Neptune in a retrograde direction, meaning it moves in the opposite direction of the planet's rotation. This unique orbital motion is thought to be the result of Triton being a captured object from the Kuiper Belt.
What moon revolves around its planet in a retrograde orbit?
Neptune's moon Triton revolves around the planet in a retrograde orbit, meaning it orbits in the opposite direction of the planet's rotation. This is a unique characteristic compared to most moons in the solar system, which revolve in a prograde orbit.
Which large Jovian moon is thought to have been captured into its present orbit?
The large Jovian moon thought to have been captured into its present orbit is Triton, which orbits Neptune. Triton's retrograde motion and unique characteristics suggest it was once a Kuiper Belt object that was captured by Neptune's gravity.
What moon has a retrograde orbit?
Neptune's moon Triton has a retrograde orbit, meaning it orbits in the opposite direction to the planet's rotation. This is unique among the major moons in our solar system.
What is retrograde motion as applied to a planet?
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
What planet has a moon that exhibits retrograde motion?
Neptune has a moon named Triton that exhibits retrograde motion. Retrograde motion is when a moon orbits its planet in the opposite direction of the planet's rotation.
What does the retrograde motion of neptune's moon Triton indicate about its origin?
The retrograde motion of Neptune's moon Triton suggests that it was likely captured by Neptune's gravity rather than forming in orbit around Neptune. This could have occurred when Triton was a wandering object in the early solar system that was captured by Neptune's gravitational pull.
What is Triton orbital period?
Triton, the largest moon of Neptune, has an orbital period of about 5.9 Earth days. It orbits Neptune in a retrograde direction, meaning it moves in the opposite direction of the planet's rotation. This unique orbital motion is thought to be the result of Triton being a captured object from the Kuiper Belt.
The apparent westward movement of a planet is known as?
The apparent westward movement of a planet is known as retrograde motion. This phenomenon occurs when a superior planet passes Earth in its orbit, making it appear to move backward in the sky relative to the stars.
What moon revolves around its planet in retrograde orbit?
The moon Triton orbits Neptune in a retrograde orbit, meaning it moves in the opposite direction of the planet's rotation. This is unique compared to most moons in our solar system, which orbit their planets in a prograde direction.
Does Neptune prograde or retrograde?
Neptune prograde, which means it orbits the Sun in the same direction as the planets in our Solar System.
What moon revolves around its planet in a retrograde orbit?
Neptune's moon Triton revolves around the planet in a retrograde orbit, meaning it orbits in the opposite direction of the planet's rotation. This is a unique characteristic compared to most moons in the solar system, which revolve in a prograde orbit.
Which large Jovian moon is thought to have been captured into its present orbit?
The large Jovian moon thought to have been captured into its present orbit is Triton, which orbits Neptune. Triton's retrograde motion and unique characteristics suggest it was once a Kuiper Belt object that was captured by Neptune's gravity.
What planet has a moon with a retrograde revolution?
Neptune. The moon is called Triton.
Was retrograde motion a theory?
Retrograde motion describes something by definition. It is not and has never been a theory.
What moon has a retrograde orbit?
Neptune's moon Triton has a retrograde orbit, meaning it orbits in the opposite direction to the planet's rotation. This is unique among the major moons in our solar system.
Why is the moon Triton on neptune famous?
Triton is the only known large natural satellite to orbit its planet in retrograde (backwards).
