Jun 24, 2022 · In the case of Aletai, the low entry angle (~6.5° to 7.3°) could contribute to the formation of the long strewn field with a unique stone skipping–like trajectory. The parameter range (e.g., initial velocity, entry angle, and initial mass), calculated from MCMC method for reference, is mainly based on current observations.

Iron, IIIE-an. Country. China. Year found. 1898. Mass. 74 t. [Museum Collection] (1) 480g. History: A new, 23 tonne mass of Aletai was found recently in a pasture of Aletai county (48°2’17"N, 88°23’3"E) in June, 2021. It was buried by soil and grass and covered with light-brown rust.
Jun 24, 2022 · Aletai are unique. In this work, a comprehensive study of petrology, whole-rock trace element geochemistry, together with radionuclide analyses and numerical modeling was carried out for Aletai irons. The results show that a 430-km-long strewn field could be generated if asteroid Aletai entered Earth’s atmosphere at a shallow angle and traveled
The Aletai asteroid would have hit the atmosphere at between 11.9 and 14.9 km/s (43,000-54,000 mph), the authors calculate, near the lower end of space rocks' impact velocities. Advertisement [H/T ...
