Because Pluto has an orbit around the Sun which is very elliptical, there are times when it crosses Neptune's orbit and becomes closer to the Sun than Neptune. For 20 years, from 1979 to 1999, Neptune was actually farther from the sun than Pluto. For now, Pluto is back to being farther from the sun. It will be more than 230 years before Neptune and Pluto trade places again. Pluto slips inside of Neptune's orbit once every 248 Earth years for a period of twenty years. 1  Javascript must be enabled to use Cool Cosmos.
Since Voyager 1 blasted off in 1977, it has skirted past the kaleidoscopic clouds of Jupiter and the icy rings of Saturn. The spacecraft is now 124 times farther from the Sun than we are, and in the time it takes you to read this paragraph will venture outward 100 miles more. Its most recent observations raise questions about our solar systemâs true reach. Although we often consider Pluto the end of the solar system, Voyager 1 is more than three times farther than that and yet still within the Sunâs domain.
