Ever looked up at the night sky and wondered about those space rocks zooming through the cosmos? You’ve probably heard terms like comet, asteroid, meteor, and meteorite, but what do they actually mean? Let’s break it down!

On December 27, 2024, a potentially dangerous asteroid named 2024 YR4 was discovered by the ATLAS telescope in Río Hurtado, Chile. This celestial object quickly caught the attention of astronomers worldwide due to its concerning trajectory. Estimated to be between 130 and 300 feet wide, this space rock is comparable in size to a football field. For context, asteroids of this magnitude have the potential to cause significant damage if they were to impact Earth. The discovery of 2024 YR4 serves as a stark reminder of the ongoing threats posed by near-Earth objects (NEOs).

On December 14, 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt became the last humans to walk on the Moon. Since then, over five decades have passed without a single crewed lunar mission. Given the rapid advancements in technology, many wonder: Why haven’t we returned?
