(662) Newtonia is an asteroid of the main belt , which on 30 March 1908 by American astronomer Joel H. Metcalf in Taunton was detected.
The asteroid was named by Z. Daniel of the Observatory of Princeton University after the small American town Newton in Massachusetts , because he could not decide whether to use the name Isaac Newton (1643–1727) or the astronomer Hubert Anson Newton (1830 –1896) should honor. The asteroid (8000) Isaac Newton has been named after Isaac Newton since 1998 .
