Watson's telegram to Europe announcing the discovery became lost, and so notification did not arrive until several weeks later.

As a result, another minor planet, later designated 176 Iduna, was initially assigned the number 175.

[4] The initial orbital elements for 175 Andromache proved unreliable, and it was only in 1893 that an accurate ephemeris was produced.

Because the orbital period is fairly close to being double that of the giant planet Jupiter, 175 Andromache initially became of interest in the study of gravitational perturbations.

The size ratio between the major and minor axes is 1.09 ± 0.09, as determined from the W. M. Keck Observatory.
