Did you know that Pluto was discovered on February 18, 1930 by Clyde Tombaugh?  While studying the orbits of Neptune and Uranus, astronomers thought that there was an undiscovered planet with an orbit event farther away than Neptune.  They called this mystery planet, “Planet X”.

To find the planet, astronomers took pictures of the night sky and looked for points of light that ‘moved’ from picture to picture.  Stars would remain in the same place in each picture, but planets would move.

After the discovery, there were over 1,000 suggestions on what to name the newly found planet.  The name “Pluto” was suggested by an 11-year-old girl.  The first two letters of the name “PL” are the initials of Percival Lowell, the founder of the Lowell Observatory where the discovery of Pluto was made.

It takes Pluto 248 earth years to orbit around the sun.  Other planets’ orbits are circular, while Pluto’s orbit is elliptical, or shaped like an oval.  In 2006 Pluto was reclassified as a ‘dwarf planet’.  In 2003 NASA launched a space probe called, “New Horizons” to study Pluto.  It will reach Pluto in July 2015.

Did you know that Pluto was discovered on February 18, 1930 by Clyde Tombaugh?  There were over 1,000 suggestions on what to name the newly found planet.  The name “Pluto” was suggested by an 11-year-old girl from England.  It takes Pluto 248 earth years to orbit around the sun.  Other planets’ orbits are circular, while Pluto’s orbit is elliptical, or shaped like an oval.  In 2006 Pluto was reclassified as a ‘dwarf planet’.  In 2003 NASA launched a space probe called, “New Horizons” to study Pluto.  It will reach the Pluto in July 2015.

We hope that you have a day filled with discovery.  Remember to use kind words, do kind things, and think kind thoughts.  We Love You.
