5 asteroids that came extremely close to Earth

Near-Earth Asteroids (NEAs) are space rocks that come within 1.3 astronomical units of Earth. NASA monitors them closely for any potential threats.

In August 2020, Asteroid 2020 QG passed just 2,950 km from Earth’s surface – the closest an asteroid has ever come without impacting.

Bennu is a small, near-Earth asteroid that passes close to Earth about every six years. 

Dinkinesh is a small asteroid located in the main asteroid belt between Mars and Jupiter. 

Asteroid Didymos and its small moonlet Dimorphos make up what’s called a binary asteroid system – meaning the small moon (Dimorphos) orbits the larger body (Didymos).

Eros, the first near-Earth asteroid discovered in 1898, is famous for being the first asteroid orbited and landed on by a spacecraft.

NASA’s Planetary Defense Coordination Office tracks NEAs and provides warnings about potential impacts using advanced telescopes and satellites.

NASA uses the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and ground-based telescopes to detect asteroids.

NASA's DART (Double Asteroid Redirection Test) mission aims to test whether we can alter the course of an asteroid to prevent a future impact.

Thousands of asteroids come close to Earth every year, but only a small fraction pose any real threat due to their size or trajectory.
