Glossary term: Cratera
Description: Uma cratera é uma depressão circular na superfície de um planeta sólido, lua ou outro objeto pequeno no espaço. Algumas crateras são vulcânicas, especialmente na Terra e em Vênus, mas a maioria é de impacto, causada pelo impacto de uma grande rocha espacial ou núcleo de cometa. Há dezenas de crateras de impacto na superfície da Terra e milhares na Lua. Os mares, as características grandes, escuras e circulares da Lua, são crateras de impacto gigantes, formadas há bilhões de anos e depois preenchidas com lava, que se solidificou desde então.

Caption: Imagem em cores reais do asteroide Ceres adquirida pela sonda espacial Dawn em maio de 2015, a uma distância de 13641 km. A proeminente e brilhante cratera à direita é Haulani. O ponto brilhante menor à sua esquerda está exposto no piso da cratera de Oxo. A ejeção desses impactos parece ter exposto material brilhante, provavelmente gelo de água.
