Lomonosov is a crater onMars, with a diameter close to 150 km. It is located in theMartian northern plains. Since it is large and found close (64.9° north) to the boundary between theMare Acidalium quadrangle and theMare 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 ofMikhail V. Lomonosov.
The impact that created the crater has been identified as a possible source oftsunami waves which washed the shores of anancient ocean formerly present in the basinVastitas Borealis.[1][2][3] In July 2019, further support was reported for anancient ocean on Mars that may have been formed by a possiblemega-tsunami source resulting from ameteorite impact creating Lomonosov crater.[4][5]
