Tillides

Tillides are a group of small, stony asteroids located in the outer region of the asteroid belt, between the orbits of Mars and Jupiter. They are characterized by their low albedo, which means they reflect very little sunlight, and their spectral features, which indicate a composition rich in silicates and metals. Tillides are believed to be remnants of larger asteroids that have been shattered by collisions over time.

The largest known tillide is 1981 Midas, with a diameter of approximately 120 kilometers. Other notable tillides include 1989 UC, 1991 BA, and 1991 VG. These asteroids are of particular interest to astronomers and planetary scientists because they provide insights into the early solar system and the processes that shaped it.

Tillides are classified into several sub-types based on their spectral properties and composition. The most common sub-types are the S-type, which are rich in silicates, and the M-type, which are rich in metals. Other sub-types include the C-type, which are carbonaceous and rich in organic compounds, and the E-type, which are enstatite-rich.

The study of tillides is an active area of research in planetary science. Scientists use various techniques, such as spectroscopy and radar imaging, to study the composition and structure of these asteroids. By analyzing the data, they can gain a better understanding of the formation and evolution of the solar system.
