Updated analysis of the dynamical relation between asteroid 2003 EH1 and comets C/1490 Yl and C/1385 Ul

Abstract

The asteroid 2003 EH1, proposed as the parent body of the Quadrantid meteor shower, is thought to be the remnant of a past cometary object, tentatively identified with the historical comets C/1490 Yl and C/1385 Ul. In this work, we use recovery astrometry to extend the observed arc of 2003 EH1 from 10 months to about 5 years, enough to exclude the proposed direct relationship of the asteroid with both of the comets. © 2008 The Authors.
