MASSIVE 150-foot Asteroid speeding at 67656 kmph towards Earth, says NASA
Asteroids can pose a significant danger to Earth, at least that's what the past incidents have proved so far! While most asteroids that enter Earth's atmosphere burn up and disintegrate before they can reach the surface, some larger asteroids can cause significant damage upon impact. The responsibility of monitoring near-Earth objects like asteroids and comets that have the potential to survive entry through Earth's atmosphere and endanger the planet falls on space agencies like NASA. Through the JPL watchboard, NASA provides advance notice of any potentially hazardous asteroids that are set to approach Earth.
