Neptune (the eighth and outermost planet) was discovered on September 23, 1846. It takes 164.79 Earth years to complete one orbit and will therefore only complete its first orbit since its discovery in 2011.
It is also worth noting that while Pluto is not longer regarded as a planet (it is now a minor planet) it was discovered in 1930 and takes 248.09 Earth years to complete an orbit.

The planet Uranus.
I am not familiar with planets evolving around any singular planet. If you are referring to orbit, the planets orbit the sun, a star, not a planet, in our solar system. Some planets have moons in their orbit.

Orbit
The planet Neptune has not completed a full orbit since its discovery in 1846. It takes Neptune approximately 165 Earth years to complete one orbit around the Sun, so it has only completed a fraction of its first orbit since its discovery.
Neptune and Pluto.
Neptune was discovered in 1846 and it takes about 165 Earth years to orbit the Sun. So, it has just completed one orbit since discovery.

A planet in an orbit greater than any of the others.An object in orbit around a single planet is a moon or satellite of that planet.
Planet Neptune
none the orbit is around the sun
Yes, when Cassini entered orbit around Saturn it did cause the planet's orbit to change.
U answer
Neptune. It takes 165 years to make one orbit.
No, a moon is a natuaral satellite and would always be in orbit around a planet. If it did'nt orbit the planet it would fall into the planet.
