Experts Discuss Hypothetical Asteroid Threat in Table-Top Simulation
A table-top simulation involving asteroid experts, NASA workers, and international partners highlighted the potential threat of a massive asteroid with a 72% chance of colliding with Earth in 14 years. With thousands of ‘near-Earth objects’ still unidentified, the exercise emphasized the need for ongoing preparedness and vigilance to protect the planet from catastrophic impacts.
Earth’s Inner Core Slowing Down Rotation, Impacting Day Length
Recent study shows Earth’s inner core is slowing down its rotation, potentially affecting the length of days. The solid mass of iron and nickel over 3,000 miles below the surface is rotating at a reduced speed, with implications for the planet’s overall rotation. Despite projected minuscule changes in day length, ongoing research sheds light on Earth’s intricate geophysical processes.
NASA Warns of Plane-Sized Asteroid Approaching Earth in 2024
NASA warns of a 98-foot plane-sized asteroid, 2024 LB4, on a trajectory towards Earth, set to make a close approach on June 16, 2024. Despite its size and proximity, NASA assures no immediate threat. Continuous monitoring by the Center for Near-Earth Object Studies highlights the importance of planetary defense efforts and asteroid research. NASA’s Jet Propulsion Laboratory tracks asteroids like 2024 LB4 using advanced telescopes and radar systems to assess potential risks. The close approach in June 2024 underscores the need for ongoing vigilance in monitoring asteroids and ensuring Earth’s safety.
