Mysterious object moving through space could be lost Soviet probe as NASA weighs in on theory

Harvard researchers identified near-Earth asteroid 1998 KY26 as potentially matching the lost Soviet spacecraft Phobos 1 based on nongravitational acceleration readings. Phobos 1 launched in 1988 and lost contact with ground control in 1989 during its mission to Mars and its moon Phobos. NASA has not confirmed the theory, and the object's origin remains unverified.
