Nereid, the third largest of Neptune’s moons (mag. 18.69) and Minor Planet Christophe

I'd like to remind any casual readers of this thread that the position of a minor planet as calculated by SkyTools depends on the orbital elements used to plot the position, and any errors are not due to a fault in SkyTools itself, but to poorly determined, and often changing orbital elements as the asteroid passes close to the earth.
