(4734) Rameau is an asteroid of the inner main belt that was discovered by the German astronomer Freimut Börngen on October 19, 1982 at the Thuringian State Observatory in Tautenburg ( IAU code 033).
The asteroid is a member of the Massalia family, a group of asteroids with low orbital inclination named after their largest member (20) Massalia .
The ageless (not osculating ) orbital elements of (4734) Rameau are almost identical with those of 15 smaller, when one of the absolute brightness starts, asteroids: (14289) 4648 PL , (28481) Shindongju , (35944) In 1999, KT 2 , ( 48034) 2001 DM 53 , (56542) 2000 HJ 63 , (56595) 2000 JX 40 , (60658) 2000 FG 48 , (109642) 2001 RA 1 , (121168) 1999 KS 1 , (147492) 2004 CW 78 , (149850 ) 2005 QN 8 , (204672) 2006 DJ 32 , (291069) 2005 YV 103 , (292821) 2006 UC 265 and (316395) 2010 TW 52 .
The track from (4734) Rameau was secured in 1991 so that numbering could be assigned. The asteroid was named on April 28 of the same year at the suggestion of Freimut Börngen after the French composer and music theorist Jean-Philippe Rameau (1683–1764). As early as 1976, an impact crater on the southern hemisphere of the planet Mercury was named after Jean-Philippe Rameau: Mercury crater Rameau .
