Earth Comparison

If You Were There

smallest planet, coldest planet, and farthest from the sun
its orbit is the most elliptical and tilted and only planet that has a moon so close to its size
Pluto remains the only planet that has never been visited by spacecraft
not discovered until 1930
it was once thought as a moon of Neptune that had somehow been pulled in to its own orbit around the sun
some expert scientist believe that Pluto thought to be a planet may be a an asteroid from the outer solar system
Pluto swings inside Neptune's orbit and is closer to the sun Pluto is the only planet that crosses another planets orbit but Pluto and Neptune will never collide
Pluto's orbit tilts so that it misses Neptune's orbit
methane ice covers parts of Pluto's surface all the time
sometimes when Pluto's orbit carries it closer to the sun some of the ice changes into gas creating a thin atmosphere
Pluto's moon Charon is only about 12,000 miles from Pluto Charon is half the size of Pluto
every 124 Earth years Charon and Pluto undergo several mutual eclipses in which each body passes in front of the other repeatedly for several years
the next eclipsing cycle will begin in 2109
the first pictures of Pluto were not taken until 1994 by the Hubble Space Telescope
the atmosphere is going to begin collapsing in the year 2010

smaller than Earth's moon
A year on Pluto takes 248.6 Earth years

if you weigh 100 lb. on Earth you would weigh 8 ounces on Pluto
if you were 10 years old on Earth, you would only be a little over one hour old
