The Discovery of Calliope

Asteroid Calliope was first discovered on December 16, 1854, by English astronomer John Russell Hind. Hind is known for his significant contributions to the field of astronomy, having discovered ten asteroids in total.

The Origin of the Name

The name "Calliope" was inspired by Greek mythology. Calliope, one of the nine Muses, is the muse of epic poetry and eloquence. The naming convention for asteroids often draws from various mythologies and cultural references.

Size and Composition

Asteroid Calliope has an estimated diameter of approximately 147 kilometers (91 miles). Its composition is believed to be primarily carbonaceous, which indicates a high presence of organic compounds, such as carbon and water ice.

Orbit and Rotation

Calliope orbits the Sun at an average distance of about 2.28 astronomical units (AU) with an orbital period of around 3.6 years. It has a moderately inclined orbit, tilted by approximately 12 degrees relative to the ecliptic plane. The rotation period of Calliope is currently unknown.
