Neptune. It was discovered in 1846 and takes nearly 165 days to make one orbit of our sun.
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. It takes 165 years to make one orbit.
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 and Pluto.
Neptune, the furthest planet from our sun.
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.
One orbit of Neptune around the sun takes about 164.79 earth years. Since its discovery in the mid-1840s it took until 2010 to complete one orbit.

The eight planets are in order in their various places. If a planet is closer to the Sun, it will have a shorter orbit and therefore will take less time to complete its orbit. If a planet is farther away from the Sun, it will have a longer orbit and will take more time to complete its orbit. For example, Earth, the third planet from the Sun and takes just a year to revolutionize it, but since Uranus, the seventh planet, is farther away from the Sun, it will take 81 years to complete its orbit.
Neptune. It was discovered in 1846, and will not complete its first orbit around the Sun since then until next year, giving it an orbit duration of roughly 165 years.
It is currently in orbit and has been since it was created.
Since we never seen Planet X, we don't know for sure. Astronomers are estimating its orbital period to somewhere between 10,000 to 20,000 years.
