668 Dora

668 Dora is a main-belt asteroid discovered on July 27, 1908, by August Kopff at the Heidelberg Observatory in Germany. It is classified as a C-type asteroid, indicating a dark surface composition rich in carbonaceous materials.

Discovery and Naming

The asteroid was discovered by Kopff, a prolific asteroid discoverer. The naming of 668 Dora is believed to be linked to Kopff's wife, Dora. This practice of naming asteroids after family members or close associates was common among early asteroid discoverers.

Physical Characteristics

668 Dora has a relatively low albedo, meaning it reflects a small percentage of sunlight. Its diameter is estimated to be approximately 28-30 kilometers. Its rotation period has been measured and is around 12 hours. Due to its dark surface and relatively small size, detailed studies of its surface features are challenging.

Orbit and Classification

668 Dora orbits the Sun within the main asteroid belt, a region between Mars and Jupiter. Its orbital parameters, such as its semi-major axis, eccentricity, and inclination, place it among the typical main-belt asteroids. Its C-type classification suggests a primitive composition, potentially offering insights into the early solar system.

Significance

While not particularly remarkable compared to other main-belt asteroids, 668 Dora contributes to our understanding of the distribution, composition, and evolution of the asteroid belt. Its discovery adds to the catalog of known solar system bodies, providing data points for astronomical research and modeling. Studying C-type asteroids like Dora helps scientists learn about the building blocks of planets and the materials present in the early solar system.
