Today 9 asteroids reach the closest point in their orbit, 2 of them are potentially dangerous! An overview of the currently largest asteroids near Earth and potential dangers.
NASA is currently aware of over 1.1 million asteroids. 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 be dangerous to our home planet. In this article we give you an overview of all the near-Earth asteroids that are passing the closest point in their orbit today.
On Tuesday, July 5th, 2022, a total of 9 asteroids will reach their closest station during the day, including 2 potentially dangerous asteroids.
The largest near-Earth asteroids today
“152637 (1997 NC1)” is currently the largest with an estimated diameter of 671 to 1500 meters asteroid near earth. “152637 (1997 NC1)” will make its closest approach to Earth at 00.00 today. The second largest near-Earth asteroid is “(2005 NY39)” and has an estimated diameter of 193 to 431 meters. “(2001 XP31)” today ranks 3rd among the largest near-Earth asteroids (99 m – 221 m).
This asteroid is coming particularly close to Earth today
The closest thing to Earth today is the asteroid “(2021 EL4)”. It approaches our planet at 11:37 p.m. at a distance of up to 7.6 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 come closer 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 a collision. About 20 percent of near-Earth asteroids are classified as potentially dangerous.
Today there are 2 potentially dangerous asteroids near Earth: “152637 (1997 NC1)” and “(2001 XP31)”.

8 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 8 Earth orbit cruisers are approaching our planet.
Apollo asteroids near Earth today: “(2001 XP31)”, “(2022 CF7)”
Near Earth Aten asteroids today: “152637 (1997 NC1)”, “(2000 LG6)”, “(2020 XV3)”, “(2021 EL4)”, “(2021 NO1)”, “(2021 SG1)”
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.
- near-Earth Amor asteroids today: “(2005 NY39)”
