Asteroid 4106, Nada, was discovered on March 6, 1989 by Toshiro Nomura and Koyo Kawanishi at Minami-Oda Observatory in Kamikawa, Hyogo, Japan. It has a period of 4 years, 207 days.
It was named for Nada High School, a prestigious all-male prep school in Kobe, Japan, where Nomura was a science teacher. "Nada" in Japanese means "the sea that is difficult to cross."
In Spanish, "nada" means "nothing", and this seems to be an astrological meaning of asteroid Nada.
