5. The apparent displacement of the position of a celestial body in the direction of motion of an observer on Earth, caused by the motion of Earth and the finite velocity of light.
6. Genetics A deviation in the normal structure or number of chromosomes in an organism.

[Latin aberrātiō, aberrātiōn-, diversion, from aberrātus, past participle of aberrāre, to go astray : ab-, away from; see ab-1 + errāre, to stray; see ers- in Indo-European roots.]
