Rosetta mission team members have named the 82-foot-tall (25 meters) boulder on Comet 67P/Churyumov-Gerasimenko "Cheops," after the largest pyramid in Egypt's famous Giza complex. The rock is much smaller than its namesake, however, which rises 456 feet (139 m) into the Egyptian sky.
Rosetta first photographed Cheops upon arriving in orbit around Comet 67P in early August. Over the past few weeks, the probe has taken close-up pictures and several wide-angle views that highlight the rock and its surrounding boulder field.
"The surface of Cheops seems to be very craggy and irregular," said Holger Sierks, the principal investigator for Rosetta's Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS), in a statement.
