Size and Shape

Asteroid Ida is classified as a minor planet and is part of the Koronis family. It was discovered by Austrian astronomer Johann Palisa on September 29, 1884. With a diameter of approximately 31.4 kilometers (19.5 miles), Ida is considered a relatively large asteroid in comparison to others in our solar system.

Composition

Spectroscopic analysis of Ida has revealed that it mainly consists of silicate rock, similar to the composition of Earth's crust. Additionally, it contains significant amounts of metal, including iron and nickel. This composition suggests that Ida might have originated from the inner regions of the asteroid belt.

Satellite Dactyl

One of the fascinating aspects of Asteroid Ida is the discovery of its natural satellite named Dactyl. In 1993, during the Galileo spacecraft's flyby of Ida, Dactyl was spotted orbiting around the asteroid. It was the first confirmed detection of a moon orbiting an asteroid, providing valuable insights into the formation and dynamics of these celestial bodies.

Discovery and Naming

Asteroid Ida was named after the nymph Ida from Greek mythology, who nursed the infant Zeus on the island of Crete. The name Ida reflects the ancient and mythological significance associated with celestial objects.

Galileo Spacecraft Encounter

The encounter between Ida and the Galileo spacecraft on August 28, 1993, marked a significant milestone in our understanding of asteroids. The close flyby provided detailed images and data, revealing the surface features and topography of Ida. This encounter also led to the discovery of Dactyl, expanding our knowledge of asteroid systems.

Hydrogen Content

Recent studies using ground-based telescopes and space missions like NASA's Dawn mission have revealed the presence of hydrated minerals on Asteroid Ida. These minerals contain water molecules bound within their crystal structure, suggesting the possibility of water-rich asteroids playing a role in the delivery of water to early Earth.

Surface Geology

Observations of Ida's surface have shown evidence of impact craters, grooves, and boulders. These features provide clues about the geological history of the asteroid and the processes it has undergone over millions of years. Further analysis of Ida's surface geology will contribute to our understanding of the dynamic nature of the asteroid belt.
