NASA is currently aware of over 1.1 million asteroids in the solar system. Thousands more of these usually irregularly shaped rock bodies are discovered every month. Special attention is paid to the so-called near-Earth asteroids, which do not move around the sun like most asteroids in the asteroid belt, but come close to the Earth’s orbit and can therefore also become dangerous to the Earth. In this article, we give you an overview of all the near-Earth asteroids that have reached the closest point in their orbit today.
On Sunday, March 19th, 2023, a total of 20 asteroids will reach their closest station during the day, including 1 potentially dangerous asteroid.
The largest near-Earth asteroids today
“(2007 FH1)” With an estimated diameter of 232 to 518 meters, it is currently the largest asteroid near Earth. “(2007 FH1)” reaches its closest approach to earth today at 11:03 am. The second largest near-Earth asteroid is “(2022 WH15)” and has an estimated diameter of 149 to 334 meters. “(2016 CL136)” today ranks 3rd among the largest near-Earth asteroids (141 m – 316 m).
This asteroid is coming particularly close to Earth today
The closest thing to Earth today is the asteroid “(2016 WH)”. It approaches our planet at 5:21 p.m. at a distance of up to 6.9 million km.
The asteroid that has come closest to us so far without impacting Earth was “(2020 QG)”. On August 16, 2020, it flew past Earth at a speed of around 44,000 km/h, just 3,000 km away. Coming from the direction of the sun, experts didn’t see it coming: it was only spotted 6 hours after its flyby. It would probably not have caused much damage on Earth even if it had collided. Because of its small size, only 3 to 6 m in diameter, it is assumed that it would have burned up in the atmosphere if it had come closer.
Potentially dangerous asteroids near Earth today
Potentially dangerous asteroids are those asteroids that are closer to Earth than 0.05 AU (approx. 7.5 million km) and have an absolute brightness of 22 mag or less. They are therefore considered large enough (at least around 140 m in diameter) to cause considerable damage in the event of an impact. About 20 percent of near-Earth asteroids are classified as potentially dangerous.
Today there is 1 potentially dangerous asteroid near Earth: “(2016 CL136)”.
(2016 CL136)

Time of the shortest distance to earth: on 03/19/2023 at 05:15
17 Earth orbit cruisers near Earth
Asteroids that cross the orbit of the earth are also called orbit cruisers. Near-Earth type asteroids Apollo cross Earth’s orbit from outside, near-Earth type asteroids Aten cross the earth’s orbit from within. Today, a total of 17 Earth orbit cruisers are approaching our planet.

Amor and Atira type asteroids do not cross Earth’s orbit. While the hard-to-discover Atira-Asteroids move completely within Earth’s orbit, approaching type asteroids cupid the earth’s orbit from the outside.
