For thousands of years, the solar system was thought to end at the planet Saturn. Then in 1781 Uranus was discovered, followed in relatively short order, (on a cosmic time scale) by Neptune and then Pluto. For the longest time, these three were called the “impersonal” planets, since it takes years for these planets to complete an orbit of the Sun. As such,the sojourn for each of these planets in a sign is measured in years instead of weeks, as is the case with personal planets, the Moon, Mercury, Venus and Mars. They become to be called as generational planets, since whole groups of people, “generations” were marked by these planets in their charts. For many years the astrology texts, the explanations of these planets were brief, declaring that the effect on the planet is on the generation, not the individual. While there is some truth to it, as noted before, there is nothing impersonal about an impersonal planet when it makes a significant aspect in your chart.
