I think planet x was the last to be discovered. Not sure
The second to last planet in our solar system is Uranus. It is located after Saturn but before Neptune.
Uranus is the second furthest planet from the sun. Neptune, now the furthest planet from the sun, was the second furthest planet from the sun after Pluto was discovered in 1930 until Pluto was reclassified as a dwarf planet in 2003.
Technically, yes. But, just a few years ago, scientists discovered a red, round, sphere-shaped hunk of rock that scientists believe may be a ninth planet(well, tenth planet if you count Pluto). It is still unclear if it really is another planet or not.
Neptune. (Note: Pluto was discovered later, but currently it is no longer recognized as a planet.)
At the end of the 17th century the furthest planet known was Saturn, and it had been known in ancient times. Uranus was discovered in 1783, Neptune in 1846.
As we are discovering more and more exoplanets almost weekly, there will never be a "last" planet discovered.
the scenod to last dwarf planet is: ceres is the second to last DWARF PLANET i think.
Pluto
Neptune, Pluto, Or planet X (Or Nibiru) are discovered. On the future, Nibiru is discovered. The Future Year: 2111

It wasn't discovered to not be a planet, it was decided to no longer be a planet. Recently, the last 2 or 3 years scientist decided (not all) it was not an official planet.
Neptune, discovered on September 23rd 1846 . Pluto was discovered in 1930, but it is now not classified as a planet but is not classed as the second largest (so far discovered) object in the Kipper belt which extends beyond the orbit of Neptune where to date over a thousand minor planets have been discovered and are being discovered daily. so it is Neptune, because it is the farthest from us. Plus the other stuff the person said was hard to understand
Neptune.
The five "classical" planets - Venus, Mars, Jupiter, Saturn and Mercury - have been known since antiquity. They are easily visible with the naked eye in a dark environment, and obviously move against the background of the "fixed" stars.Neptune was the next planet discovered by scientist.To get more interesting information check outwww.google.com search what was the second planet discovered it will gice you tons of information

Nope.. the second planet in the solar system is VENUS
The last planet to discover during the 20th century was Pluto. But it's a dwarft planet so it should maybe be Neptune.
