4183 Cuno

4183 Cuno is a stony asteroid classified as an Amor asteroid. Amor asteroids are a group of near-Earth asteroids that approach the Earth's orbit but do not cross it. This means their perihelion (closest point to the Sun) distance is between 1.017 AU and 1.3 AU. Cuno was discovered on June 5, 1959, by E. L. G. Leonard at Mount Lemmon Observatory.

Its orbit is relatively well-determined, allowing for accurate predictions of its future positions. Cuno's orbital characteristics, such as its eccentricity and inclination, have been studied extensively. It poses no immediate threat to Earth, as its orbit, while near Earth's, does not intersect it.

The physical characteristics of Cuno, such as its size and albedo (reflectivity), have been estimated through various observations. These estimates can vary depending on the method of observation and the data used. Generally, its diameter is estimated to be a few kilometers across. Further observations and studies are ongoing to refine our understanding of Cuno and other near-Earth asteroids, which helps in understanding the potential risks and resources they may represent.
