Izquierdo (crater)
Encyclopedia
Izquierdo is a crater on Mercury
located to the east of Beagle Rupes
and Sveinsdóttir crater. The floor of Izquierdo is smooth, the result of having been partially filled with volcanic lava. Circular outlines of the rims of “ghost craters” – smaller, older craters that have been largely buried by the lavas that infilled the basin – are visible in a few places on Izquierdo’s floor. The remnants of a buried inner ring are also barely discernable in spots. There have been more recent impacts into the floor of Izquierdo, resulting in some small, sharply defined craters.
Mercury (planet)
Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits...

Beagle Rupes
Beagle Rupes is an escarpment on Mercury, one of the highest and longest yet seen. It was discovered in 2008 when MESSENGER made its first flyby of the planet. It has an arcuate shape and is about 600 km long. The scarp is a surface manifestation of a thrust fault, which formed when the planet...
