Seas which are not on Earth

Lunar maria are very big areas on the Moon. In the past, people thought they were water and called them "seas".

Scientists think that there is liquid water under the ground on some moons, for example Europa.

Scientists also think that there are liquid hydrocarbons on Titan, but a better name is "lakes", not "seas".
