The number of planets has not changed. Our (human) awareness of the planets has changed over time and the definition of "planet" has changed recently. Neptune is the only planet (today's definition where Pluto is not a planet) which was discovered after 1825 (Uranus was discovered in 1781 by Sir William Herschel).
Neptune was predicted and observed by John Couch Adams in 1846 (and independently by Urbain Jean Joseph Le Verrier).
