Neptune. It takes 165 years to make one 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 (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.
Neptune, the furthest planet from our sun.
Neptune. It was discovered in 1846 and takes nearly 165 days to make one orbit of our sun.
The moon closer to the planet would complete an orbit first because it has a smaller orbit, which means it has a shorter distance to travel around the planet compared to the moon that is farther away.
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.
It takes 88 days for mercury to complete an orbit.

Orbit
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total. Its distance means that is has further to go to complete one orbit, while it also means that the planet travels the slowest. The further a planet is from the gravitational pull of the sun, the slower it will move tangentially.
It takes Earth 365 and 1/4 days to complete an orbit.
