Chang'e 3 (left, M147290066LR) and Chang'e 4 (right, M1303619844LR) are very similar in size and instrumentation. The Chang'e 3 image looks a bit fuzzier because the landing site is at 44° north latitude where the LRO orbit is about twice as far from the Moon relative to the Chang'e 4 site at 45° south latitude (1.6 meter pixels enlarged to 0.85 meter pixels; 5.2 feet vs. 2.8 feet). Each panel is 463 meters (1520 feet) wide, large arrows indicate landers and small arrows indicate rovers.
