43-Foot Asteroid's Close Encounter with Earth | Unveiled by NASA 43-Foot Asteroid's Close Encounter with Earth | Unveiled by NASA Understanding Asteroids : What are asteroids? :  Asteroids primarily consist of rocky material left over from the formation of the solar system and its planets, dating back about 4.6 billion years.  The majority of these asteroids are situated within the asteroid belt between Mars and Jupiter, estimated to contain around 1 million asteroids. Their Nature : Asteroids orbit the sun, exhibiting either flattened or circular trajectories.  Their movement lacks a precise path, often tumbling or moving erratically through space. They're commonly known as 'minor' celestial bodies. NASA's Discovery : The Defence Coordination Office at NASA recently disclosed that an asteroid from the Apollo Group made a close pass by Earth on December 12.  This office is tasked with monitoring the sky and near-Earth objects, utilizing advanced spac...
