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.
Neptune and Pluto.
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.
A planet's revolution is its orbit around the sun. A planet's rotation is its movement about its axis. For example, the Earth's revolution around the sun takes 365.26 days, and its period of rotation is 24 hours.
A revolution is the period it takes for the planet to revolve one time around the sun. Its otherwise known as the planet's year.
I believe that if a planet makes one revolution, such as the Earth or Moon, it has completed its orbit once.
The rotation of a planet refers to the planet spinning like a top; a "revolution" is the time required for the planet's orbit around the Sun.
Around its axis is a day. Around its orbit is a year.
That's the planet Mars .
When you travel around the Sun or a planet, due to gravitational attraction, it is called an "orbit". It is also a "revolution" around the Sun or planet.
