2.  2,302 kilometers in diameter  About 2/3 the size of the moon  The diameter of Pluto is roughly ½ the width of the United States

3.  There are no pictures of Pluto showing its color  Pluto is perceived to be grey like the moon  Pluto has lots of methane icecaps and astronomers say that the dwarf planet is rocky

4.  One revolution around sun for Pluto takes 90,520 days or 248 earth years  Pluto rotates all the way around its axis in around 153 hours or 6.39 earth days  Pluto is tilted on its axis at 122.5 degrees

5.  Pluto has a density of 2.05 grams/cm 3  Earth has a density 5.52 grams/cm 3  Pluto is 2.7 times less dense than Earth

6.  Pluto’s gravity is far less than Earth’s  If you weigh 100 pounds on Earth, you would weigh about 6.5 pounds on Pluto  The gravitational acceleration on the surface of Pluto is about 2.2 feet/second squared

7.  Pluto’s atmosphere, when present is composed of carbon monoxide, methane, and nitrogen  When Pluto is closest to the sun, some of the elements turn to gas and form an atmosphere  When Pluto is far from the sun, the gas in the atmosphere solidifies and the atmosphere disappears

8.  Pluto’s surface is mainly frozen methane, and carbon monoxide, as well as ice  The core of Pluto is rocky so scientists think there could be rocky surface on Pluto as well Artist’s interpretation 

9.  Pluto has a rocky core surrounded by a mantle of ice, nitrogen, and methane  Pluto is about 50-70% rock  Ice, methane, and nitrogen make up the rest

10.  It’s not known if Pluto has a magnetic field for sure  Pluto’s small size and slow rotation are signals that Pluto has little or no magnetic field

11.  Pluto has 5 moons  The two newest moons Kerberos and Styx were discovered in 2011 and 2012  Pluto’s main moon Charon is more than half the size of Pluto itself and some people consider it to be a second dwarf planet

12.  In January of 2006, NASA launched a spacecraft to Pluto, it will arrive in 2015  Pluto was named by an 11 year old girl  This girl gave her idea to her grandpa, who then submitted the name to the Lowell observatory  Pluto and its moons are all named after things in the Grecian underworld

13. Pluto fact chart Size 2,302 km in diameter, 2/3 diameter of the moon, ½ width of U.S. General color/features No actual color pictures, perceived to be grey and rocky with methane icecaps and lots of ice Days and years One rotation is 6.39 earth days, one revolution is 248 earth years Density 2.05 grams/cubic centimeter Gravity 2.2 feet/second squared Atmosphere composition Only has and atmosphere when close to sun, made of gaseous nitrogen, carbon monoxide, and methane Surface composition Frozen methane, nitrogen, carbon monoxide, and ice. Rocky Interior composition Rock core with ice mantles, traces of nitrogen and methane Magnetic field Very weak, if any at all Moons 5 moons, Charon, Nix, Hydra, Styx, and Kerberos Unique things Space mission will reach Pluto in 2015
