The metallic core extends from the center to a large fraction of the planetary radius. Radar observations show that the core or outer core is molten.

Radar echoes (red) are received at the Goldstone antenna and at the Robert C. Byrd telescope in Green Bank, West Virginia.

Credit line: Jean-Luc Margot Caption: Illustration of the trajectory (green circles, one second time interval) of radar speckles tied to the rotation of Mercury. Observers measured how long it takes for the pattern to travel between two antennas (red triangles) to measure the rotation rate of Mercury.
