Scientists have evidence of and say that a new Neptune sized planet lurks beyond the edge of our solar system. There has been no visual sighting of this planet. However it is probably so far out it will be very difficult to find given present technologies.
They are categorized as "dwarf planets" now, leaving only 8 regular planets in our solar system. The names of all the dwarf planets are:CeresPlutoHaumeaMakemakeEris
There are currently over a thousand known planets, most of them discovered recently; I would guess that currently, dozens of planets, perhaps over a hundred planets, are discovered every year.
It has been suggested that you want to know how many major planets were discovered during the year 1850. If so, the answer is "none".However, if you want to know how many were discovered up to the year 1850, then if you exclude the minor planet Ceres and any moons, the answer is 8, as follows:MercuryVenusEarthMarsJupiterSaturnUranusNeptune (Discovered in 1846)
Mercury has been known since ancient times, so there is no specific year in which it was discovered. It is one of the five planets visible to the naked eye and was observed and documented by various civilizations throughout history.
The same planets that orbit today, though Uranus and Neptune had yet to be discovered, along with Pluto (now regarded as a Dwarf Planet).

this has been discovered in the year of 1941
Neptune was discovered on September 23rd, 1846.
The same number as there are now, but they weren't all discovered by then. Mercury, Venus, Earth Mars, Jupiter, and Saturn have been known since ancient times. Uranus was first recorded in 1690 Neptune was discovered in 1846 Pluto was discovered in 1930, and later declassified as a planet. So, in 1780, we knew of 7 planets,

It was discovered before recorded history.
Know ones know the date is ancient but it has been said to have been discovered in BC

MercuryIn this solar system, that would be Mercury at about 88 Earth days. There have been planets discovered around other stars which blaze around their suns in a matter of hours instead of days.
