2003 EH1
Asteroid 2003 EH1 is a near-Earth asteroid.[1][2]
Its 5.52 year orbit is highly eccentric, and the asteroid is believed to be a former comet that has lost all the volatile material that comets shed that make them shine brightly, when they approach Sol, our sun.[1] The asteroid is 3 kilometres (1.9 mi) in diameter.
In 2003 Astronomer Peter Jenniskens proposed that the asteroid was the source of the Quadrantid meteor shower.[1]

Meteor showers are usually the residue that collects in the orbits of comets. The Quadrantids are associated with an asteroid -- 2003 EH1. It is thought to be the nucleus fragment from a comet break-up in the 1490s. It was classified as an asteroid when it was discovered by a near-Earth asteroid telescopic survey in 2003.
