This full-resolution radar mosaic from Magellan at 52 degrees north latitude, 170 degrees east longitude, shows a 94 kilometer (56 mile) segment of the longest channel discovered on Venus to date. The channel is approximately 1.8 kilometers (1.1 miles) wide. At over 7000 kilometers (4200 miles) long, it is at least several hundred kilometers longer than the Nile River, Earth's longest river; thus, making it the longest known channel in the solar system. Both ends of the channel are obscured, however, so its original length is unknown.
