What you’re seeing in the image sequence is twin-lobed, dog-boned shaped asteroid 216 Kleoptra. Discovered on the night of April 10th, 1880 by astronomer Johann Polisa from the Austrian Naval Pola Observatory, the asteroid ranges on a 4.7 year orbit, from a perihelion 2.1 Astronomical Units (AU) from the Sun, to a distant aphelion of 3.5 AU.
