171923

171923 is a large main-belt asteroid located in the asteroid belt between the orbits of Mars and Jupiter. It is a polymorphic asteroidequiprojective, meaning its rotation period and size can be projected based on observations. The asteroid was discovered on August 2, 1923, by German astronomer Max Wolf at the Heidelberg Observatory in Heidelberg, Germany.

Astronomical observations of 171923 have yielded some distinctive characteristics. The asteroid has a slow rotation period of 15.498 hours, and its average diameter is estimated to be around 22 kilometers. Its surface is likely to be composed of a mix of dark and light minerals, potentially resulting in a highly reflective albedo of 0.485.

In terms of its orbital characteristics, 171923 follows a moderately eccentric trajectory around the Sun, with an orbital period of approximately 3.548 years. Its semi-major axis measures 417,996 kilometers, placing the asteroid in the stable'menonite' regime of the asteroid belt. This indicates a relatively low risk of the asteroid being perturbed into a highly eccentric or Jupiter-crossing orbit.

Little is known about the origins and evolution of 171923, but studies suggest that its surface features may provide clues to its formation and composition. Further analysis of its albedo, spectral classification, and small-scale topographic features could shed more light on the asteroid's geologic and meteorological history.
