Planetary defense experts have expressed their concern in a new survey that growing satellite numbers in orbit around Earth may impact asteroid detection.

The two near-Earth asteroids (NEAs), dubbed 2016 CZ31 and 2013 CU83, will make their close approaches to Earth only a day apart.

Previously unknown asteroids have been found in a rarely surveyed part of the sky between the Sun and Earth that could hide more.

2022 NE and 2022 NF are two asteroids detected only two days before they each came within as little as 55,000 miles of Earth.

An expansion to the Asteroid Terrestrial-impact Last Alert System (ATLAS) system allows it to scan the entire night sky every day.

NASA's Near-Earth Asteroid (NEA) Scout will fly with the Artemis 1 mission's SLS rocket, set to observe the smallest asteroid yet.

NASA's new next-generation near-Earth asteroid impact monitoring algorithm has now been deployed, ready to protect our planet.
