A fragment of 2024 BX1
Sample of Ribbeck found after 6 days and showing terrestrial alteration, giving the sample a brown color
Olivine in Ribbeck, showing fracture lines, indicative of shock metamorphism
Thin sections of 2024 BX1 samples, with enstatite crystals (En), olivine (Ol), plagioclase (Plag) and metal (Met)
