Strewn field, as a product of meteoroids\/asteroids breakup, comprehensively reflects the trajectory, dynamics, and physical properties of meteoroids\/asteroids. It typically has a length of several to a dozen kilometers. Nevertheless, the recently found massive Aletai irons in the northwest China comprise the longest known strewn field of ~430 kilometers. This implies that the dynamics of Aletai could be unique. Petrographic and trace elemental studies suggest that all the Aletai masses exhibit unique compositions (IIIE anomalous), indicating that they were from the same fall event. Numerical modeling suggests that the stone skipping\u2013like trajectory associated with a shallow entry angle (e.g., ~6.5\u00b0 to 7.3\u00b0) is responsible for Aletai\u2019s exceptionally long strewn field if a single-body entry scenario is considered. The stone skipping\u2013like trajectory would not result in the deposition of large impact energy on the ground but may lead to the dissipation of energy during its extremely long-distance flight.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ye Li, Bin Li, Weibiao Hsu, A.
