The Ida Facula (also Mons Ida ) is a mountain on the Jupiter moon Amalthea . The mountain is a "twin" of Lyctos Facula . Ida is up to 20 km high. The surface of the satellite is colored dark red, which scientists attribute to volcanic eruptions of the neighboring moon Io , namely the Tupan-Patera .

Ida Facula is an elongated mountain with a length of 50 km. This mountain was discovered by Voyager 1 in 1979 and later photographed in greater detail by Galileo. Why the facula on Amalthea are lightly colored is not yet sufficiently clear. It is believed that a meteorite released this light mass.

Naming

The mountain was named in 1979 by the IAU after Mount Ida on the island of Crete .
