Solar System Scratchpad

[Boiler Plate]
Mercury

A large double-rimmed impact basin on Mercury, 180 miles in diameter. One of the youngest seen. First seen in its entirety during Messenger's third flyby. Its floor has been resurfaced with the most recent volcanism detected on the planet so far and the youngest volcanic surface, probably under 2 billion years old. These plains differ in color than the surrounding area. A volcanic vent was discovered to the north of the crater. The impact may have risen the temperature of the mantle area to the melting point, which spurred the vulcanism. Fourth crater found (after Caloris, Rembrandt, and Raditladi) to have extensive tectonic features, which are of unknown origin.
