1998 KY26
1998 KY26 is a small, near-Earth asteroid. It's notable primarily for its extremely rapid rotation period, approximately 10.7 minutes. This rapid rotation classifies it as a fast rotator, and understanding its composition and structural integrity is of significant interest to planetary scientists.
The asteroid was discovered in 1998, hence the '1998' designation. The 'KY26' portion refers to the specific sequence of discovery within that year, following the International Astronomical Union's naming convention for minor planets.
Due to its small size (estimated diameter of around 30 meters), 1998 KY26 is difficult to observe. Its rapid spin raises questions about its internal structure; such high rotational speeds often indicate a monolithic composition or a 'rubble pile' structure held together by cohesive forces and gravitational attraction. Further study of its spectral properties and potential radar observations are needed to better determine its physical characteristics.
While 1998 KY26 is classified as a near-Earth asteroid, its orbit is well-understood, and current calculations indicate no significant threat of impact with Earth in the foreseeable future. Its primary importance lies in its value as a research subject for understanding the behavior and characteristics of small, rapidly rotating asteroids, and for informing future asteroid deflection strategies.
