In the field of astrology, generational planets are planets that affect an entire generation of people. The generational planets are the outer planets Uranus, Neptune, Pluto, Sedna, and Quaoar. Uranus was discovered by amateur astronomer William Herschel on 13 March 1781. Uranus exhibits the ideals of the 18th century, where people such as Benjamin Franklin endeavoured to use their inventive mind to move man into a more enlightened era. It has an orbit of 84 years, staying in each sign of the zodiac for approximately 7 years. Uranus is considered to be a higher octave of Mercury, which means that as people develop within their selves, their character and means of communication will exhibit more influences of the sign and house of Uranus. In essence, Uranus can be seen as a person's higher self. Because it takes Uranus 84 years to travel through the zodiac, transiting Uranus just might conjoin the natal Uranus within a person's lifetime. Neptune was discovered on 23 September 1846.

Neptune is considered to be the higher octave of Venus because both planet's are gaseous and both strive to achieve the higher ideals of mankind; Venus through the adoption of beauty and Neptune through unconditional love. Because Neptune has such a long orbit, an individual may see transiting Neptune form an opposition to their natal Neptune. Pluto was discovered by Clyde W. Tombaugh on 18 February 1930. When Pluto was first discovered, it was initially known as Planet X. Astronomers had been searching for another planet past Neptune, hoping to solve the dilemma of its rather irregular orbit. It is now known, however, that the perceived irregular orbit of Neptune was the result of a mathematical error because Pluto, being a planetoid smaller than our own Moon, was far too small to affect any type of gravitational pull on the gas giant. Pluto is very much a 20th-century planet and refers to the two world wars, and weapons of mass destruction, nuclear power, and a desire
