Eos was discovered on January 18, 1856, by the German astronomer Hermann Goldschmidt. Goldschmidt made significant contributions to asteroid discoveries during his career, and Eos was among his notable findings.


Eos is named after the Greek goddess of dawn. The name perfectly symbolizes the brilliance and freshness associated with the rising sun, mirroring the significance of this asteroid in our understanding of the early solar system.

Physical Characteristics

Size and Composition

Eos has an estimated diameter of approximately 95 kilometers (59 miles). Its composition primarily consists of silicate rock, similar to many other asteroids found in the main asteroid belt between Mars and Jupiter.

Surface Features

Studies of Eos reveal a diverse range of surface features, including impact craters, ridges, and grooves. These features provide valuable insights into the geological history of the asteroid and the processes that have shaped its surface over millions of years.

Rotation and Orbit

The rotation period of Eos is approximately 6.8 hours, meaning it completes one full rotation on its axis in this time. Eos orbits the Sun at an average distance of about 2.73 astronomical units (AU).

Classification in the Main Asteroid Belt

Eos is classified as a member of the main asteroid belt, which is a region located between the orbits of Mars and Jupiter. It is one of the many asteroids that populate this vast celestial neighborhood.

Belonging to the Eos Family

Eos belongs to the Eos family of asteroids, a cluster of objects sharing similar orbital characteristics. The formation and evolution of asteroid families provide valuable clues about the history and dynamics of the main asteroid belt.

Eos' Spectral Classification

Eos has been classified as an S-type asteroid based on its spectral characteristics. S-type asteroids are composed primarily of nickel-iron mixed with silicate materials and are among the most common types found in the asteroid belt.

Scientific Significance

Understanding Early Solar System Formation

Studying asteroids like Eos contributes to our understanding of the early solar system's formation. By analyzing their composition and structure, scientists can gain insights into how planets and other celestial bodies evolved over billions of years.

Potential Resource Exploration

Asteroids have gained attention for their potential as valuable resources. The study of asteroids like Eos may aid in future endeavors exploring space mining and extracting precious metals, minerals, and even water for interplanetary missions.

Impact Hazard Assessment

Characterizing asteroids, including Eos, is crucial for assessing potential impact hazards on Earth. By understanding their orbits, sizes, and compositions, scientists can better predict and mitigate the risks associated with potentially hazardous asteroids.
