Moreover, the uncertainty surrounding the asteroid's composition significantly affects predictions about its behaviour during atmospheric entry. Consequently, scientists are diligently gathering more data to improve their predictions. Scientists lack precise data on its composition, density, and porosity. This lack of complete data influences predictions about its behaviour upon entering Earth's atmosphere. Determining the asteroid's composition is paramount to estimating its impact effects. 

Atmospheric Entry Scenarios and Potential Consequences 

Experts have outlined various scenarios for 2024 YR4's potential atmospheric entry. Crucially, the asteroid's composition plays a vital role in determining its impact effects. Scientists have identified possibilities based on the object's material makeup. Consequently, determining the exact composition of the asteroid is critical in predicting its impact. Experts estimate that 2024 YR4 likely consists primarily of rock rather than metal. This composition suggests it might fragment during atmospheric entry. However, fragmentation could still result in significant damage, as highlighted by Dr. Kathryn Kumamoto of the Lawrence Livermore National Laboratory. 

Furthermore, historical events provide crucial context for understanding potential outcomes. The Tunguska event of June 30, 1908, serves as a primary reference point. This incident involved a similarly sized rocky asteroid that exploded above Siberia. The resulting blast wave released energy equivalent to 12 megatons, devastating an area spanning 2,150 square kilometres. This historical precedent underscores the potentially devastating impact even a relatively small asteroid can have. Furthermore, scientists examine historical precedents to understand the scale of potential effects. This historical context aids in risk assessment. 

Assessing Asteroid Impact Scenarios: Insights from Dr. Lorien Wheeler's Research 

Meanwhile, Dr. Lorien Wheeler of NASA's Asteroid Threat Assessment Project has analysed oceanic impact scenarios.
