The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [10] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
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 ...

Four other asteroids were also included in the warning. The large asteroid, named by the space organization as "2024 ON," is about 950 feet in diameter and is 621,000 miles from Earth, NASA said.
Asteroid close approaches to Earth in 2024 include: Asteroid Perigee Date in 2024 2009 JV 1: 0.0571 AU (19.21 LD) January 5 2021 BL 3: 0.0441 AU (17.16 LD) January 23 [1]
NASA has identified multiple asteroids expected to pass near Earth in the next two days, including one that is the size of a football stadium. NASA reports 'potentially hazardous' stadium-size ...
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2023. [1] As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth.
