Can you find the longitude of this orbit's ascending node?

At a certain moment, an asteroid had this position in heliocentric ecliptic coordinates.

x = +0.5877971

y = -2.098983

z = -0.008080998

At the same moment, the asteroid had this sun-relative velocity (also in HEC).

Vx = +11461.5 m/s

Vy = +3209.6 m/s

Vz = +17.9 m/s

What is the longitude of the ascending node for the asteroid's orbit?


The distances (x, y, z) are given in astronomical units.

    Sounds like David S. is taking a course in mathematical astronomy. This is a subject that I have not studied, and I am wondering about a good text. With six numbers given, it would be possible to calculate all of the particulars of the orbit, including the ascending node.
