Description: How many near-Earth objects have been found thus far, and did any asteroids pass by Earth last month that captured the interest of our Planetary Defense experts? Watch to find out the answers to these questions and more in this month’s Planetary Defense by the Numbers video. Near-Earth objects (NEOs) are asteroids and comets that orbit the Sun and come within 30 million miles of Earth’s orbit. While many NEOs have been found and closely studied, NASA’s Planetary Defense Coordination Office was established to manage the agency’s ongoing efforts to find, track, study, and if necessary, lead efforts to mitigate a potentially hazardous NEO that could pose a potential impact threat to Earth.
