All of the planets have been revolving around the Sun since they were formed billions of years ago. There was no start, so to speak, in 1846, nor was there an end, so to speak, in 2011. However, that period of time is 164 years, and it is known that Neptune has a period of revolution of 164.8 years, so you must be talking about Neptune.

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.
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.
One year on Neptune is the same as 164.8 Earth years. The planet was discovered in 1846 and has only completed a single revolution since then.
The planet Neptune.
"Neptune" was discovered on September 23, 1846.
Pluto

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 was named after the Greek god of the sea.
Neptune has the slowest and longest orbit. It has a radius of 30 astronomical units (i.e. 30 times as far as the Earth), and it takes 165 years to go round once. So it has been round almost exactly once since it was discovered in 1846. It was discovered officially on September 24 1846, and it completed its first revolution since discovery on June 30 2011.
