Template:R from moveJanuary 17, 1997) was an American astronomer known for discovering Pluto in 1930.


Tombaugh was born in Streator, Illinois.[1] After his family moved to Burdett, Kansas, Tombaugh planned to attend college. After a hailstorm ruined his family's farm crops, he no longer had money for the expense of college.[2]

After he discovered Pluto, he did go to college at the University of Kansas and graduated with two degrees in astronomy.
