Ida and Dactyl in enhanced color
Galileo captured this image of asteroid Ida and its moon Dactyl about 14 minutes before its closest approach on August 28, 1993.

The range from the spacecraft was about 10,500 kilometers (6,500 miles). This was from the imaging sequence that produced the discovery of Dactyl. The color is based on violet and infrared filters; it represents actual variations on the surface of Ida, but has little relationship to the colors that human eyes would see.

Most NASA images are in the public domain. Reuse of this image is governed by NASA's image use policy.

Original image data dated on or about August 28, 1993
