The reason the name Eva was chosen remains unknown, though Karl Ludwig Littrow suspected a "worldly origin" ("Mit dem Namen könnten wir wie bei Miriam wieder den biblischen Boden zu betreten glauben, wenn wir bei diesem Entdecker nicht an Taufen weltlichen Ursprungs gewöhnt wären").

[6] The orbital elements for 164 Eva were published in 1877 by American astronomer Winslow Upton.

[7] It is categorized as a C-type asteroid and is probably composed of primitive carbonaceous chondritic materials.

This is consistent with a previous study reported in 1982 that listed a period estimate of 13.66 hours.

With a perihelion of 1.718 AU 164 Eva is the closest asteroid over 100 kilometers to approach the orbit of Mars.
