How Long is a Year on Pluto?

16 May , 2008 by

Pluto takes 248 years to complete each orbit around the Sun. So a year on Pluto lasts 248 years. During this period, Pluto travels around the Sun in a very elliptical orbit. At its closest point, or perihelion, Pluto gets as close as 4.4 billion km from the Sun. At its most distant point, or aphelion, Pluto is 7.4 billion km from the Sun.

You can also look through these books from Amazon.com if you want more information about Pluto.

With this widely eccentric orbit, the temperatures on Pluto can very a significant amount. Temperatures can plunge to 33 kelvin, or -240 Celsius.

During this orbit, Pluto can actually get closer to the Sun than Neptune. The last time this happened was on February 11, 1999.
