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.
On average, Pluto is 40 times further from the sun than the Earth is. From Pluto, our sun would be 1,000 times dimmer than it is seen from Earth. The dwarf planet's surface is covered with patches of frozen methane, with a hazy atmosphere including methane gas. What the sun might look like from the surface of Pluto: From the distant dwarf planet, the sun would be 1,000 times dimmer than it is seen from Earth. The computer-generated artist's impression is based on one possible idea of what Pluto's surface is like, where the surface is covered with patches of methane.
