The original mandate to NASA given by the United States Congress in 1998 was to detect 90% of near-Earth asteroids over 1 km (0.62 mi) diameter (that threaten global devastation) by 2008. [20] NASA's PDCO considers objects with a diameter of at least 1 km (0.62 mi) capable of creating an impact crater at least 10 km (6.2 mi) across and causing ...
Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth. Rows highlighted grey indicate a planet or main-belt asteroid
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance, which are cataloged by the Center for Near-Earth Object Studies (CNEOS). [1]
Four large asteroids will make their closest approaches to Earth on Thursday, each passing by the planet within a 24-hour time frame. Two had already zipped past early in the morning, according to ...
A large asteroid known as 2024 YR4 has grabbed headlines this week as scientists first raised its chances of hitting earth, then lowered them. The latest estimate says the object has a 0.28% ...
Asteroid 2024 YR4 has a 2.8% to 3.1% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit to see how much of a risk the space rock poses.
An asteroid the size of a small truck will pass by Earth tonight, making one of the closest approaches to the planet ever recorded. Asteroid 2023 BU will zoom over the southern tip of South ...
Below is an example list of near-Earth asteroids that passed or nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2022. During 2021 over 1000 asteroids passed within 10 LD (3.8 million km) of Earth.
