Rosetta’s amazing images of huge boulders and deep cliffs on comet

NEW YORK: The European Space Agency’s Rosetta orbiter is continuously taking snaps and sending amazing images of the comet’s nucleus and beams back to Earth.
This picture was taken on Dec. 10 by Rosetta’s NavCam when the orbiter was 12.5 miles away. The smaller lobe of the rubber-duck-shaped comet is on the right side of this picture, and the larger lobe is on the left. The smooth-looking slope with the boulders is the comet’s skinny neck.
NASA’s website featured a slightly altered image of the cliffs as its astronomy picture of the day Tuesday. NASA’s version highlights the steepness of the jagged cliffs seen above.
The authors of the NASA page write that the wall of the cliff rises about 1 kilometer (0.6 of a mile) high. That may sound treacherous, but because the comet’s gravity is low — Earth’s gravity is several hundred thousand times stronger — a person could probably jump off the edge and land without getting hurt.
Let’s get back to that smattering of boulders in the comet’s midsection. Although they look small in the picture, the biggest ones are actually about 65 feet across.
