419 Aurelia is a main-belt asteroid that was discovered by German astronomer Max Wolf on September 7, 1896, in Heidelberg. It is classified as an F-type asteroid.

Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave a "somewhat irregular" light curve with a period of 16.784 ± 0.001 hours and a brightness variation of 0.07 ± 0.01 in magnitude. When allowing for varying aspect angles and changes in mean motion, this result is consistent with past studies.^[5]
