Tridimensional model with large level of detail and reliability of the Bacubirito meteorite is determined by laser scanner measurements. By means of this model and densities published in the literature, we estimate the mass, main geometrical quantities, and regmaglypts distribution on the meteorite. A Monte Carlo method is proposed for uncertainty estimations of the derived geometrical magnitudes. The Bacubirito meteorite mass is m = 19.43 ± 0.51 tons with a maximum length of 4.130 ± 0.005 m; Bacubirito is set as the world’s fifth largest and the longest reported to date.

Bacubirito 陨石的新几何分析

Bacubirito 陨石的立体模型具有大量细节和可靠性，是通过激光扫描仪测量确定的。通过该模型和文献中发表的密度，我们估计了陨石上的质量、主要几何量和regmaglypts分布。提出了一种蒙特卡罗方法，用于对导出的几何幅度的不确定性估计。Bacubirito 陨石质量为 m = 19.43 ± 0.51 吨，最大长度为 4.130 ± 0.005 m；Bacubirito 被设置为世界第五大，也是迄今为止报道时间最长的。
