Near-Earth Asteroids (NEAs)

Near-Earth Asteroids (NEAs) are space rocks that orbit the Sun and come close to Earth's orbit. They vary in size from small boulders to objects hundreds of kilometers across. NEAs are important to study because they can impact Earth, potentially causing damage depending on their size and speed. Scientists track their orbits to predict future positions and assess any potential threat. While most NEAs pose no immediate danger, understanding them helps us prepare for and possibly defend against future impacts, and also offers insights into the history of our solar system.
