Lomonosov is a crater on Mars, with a diameter close to 150 km. It is located in the Martian northern plains. Since it is large and found close (64.9° north) to the boundary between the Mare Acidalium quadrangle and the Mare Boreum quadrangle, it is found on both maps. The topography is smooth and young in this area, hence Lomonosov is easy to spot on large maps of Mars.

The crater was named in 1973 in honour of Mikhail V. Lomonosov.

The impact that created the crater has been identified as a possible source of tsunami waves which washed the shores of an ancient ocean formerly present in the basin Vastitas Borealis.[1][2][3] In July 2019, further support was reported for an ancient ocean on Mars that may have been formed by a possible mega-tsunami source resulting from a meteorite impact creating Lomonosov crater.[4][5]

  • Channels made by the backwash from tsunamis, as seen by HiRISE. Tsunamis were probably caused by asteroids striking the ocean.

Coloring of the base map indicates relative elevations, based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Whites and browns indicate the highest elevations (+12 to +8 km); followed by pinks and reds (+8 to +3 km); yellow is 0 km; greens and blues are lower elevations (down to −8 km). Axes are latitude and longitude; Polar regions are noted.
