Question

Quizplus · Accepted Answer

The question asks for the name of Mercury's twin basin to Mare Orientale on the Moon. The only option that fits this description is Caloris, which is a large impact basin on Mercury that is roughly the same size as Mare Orientale. The other options either do not match the description or are features on different planets. The question specifically asks for the name of the twin basin on Mercury, and the correct answer is Caloris. Galileo is a reference to the famous astronomer and has no relation to a basin on Mercury. Mare Marineris is a feature on Mars, not Mercury. The weird terrain is not a specific feature and Valhalla is a large multi-ring impact basin on Jupiter's moon, Callisto, not Mercury.
