Name
Kep1er was a name that was suggested and created by the fans of the show, Planet Guardians, through the website Naver. The word means 'Kepler' which derived from Johannes Kepler and the Kepler's laws of planetary motion. The literal meaning of 'Kepler' in the dictionary is a small crater in the North-west quadrant of the moon, centre of a large bright ray system. The name also kept a relation to Girls Planet 999 by keeping the '플' from the Korean translation of the name, '걸스플래닛999'.
