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 rather 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 are passing the closest point in their orbit today.
On Tuesday, May 17th, 2022, a total of 5 asteroids will reach their closest station during the day, including 1 potentially more dangerous asteroid.

The largest near-Earth asteroids today

“495615 (2015 PQ291)” With an estimated diameter of 763 to 1706 meters, it is currently the largest asteroid near Earth. “495615 (2015 PQ291)” makes its closest approach to Earth at 09:37 today. The second largest near-Earth asteroid is “(2021 TA8)” and has an estimated diameter of 150 to 336 meters. “(2013 UX)” today ranks 3rd among the largest near-Earth asteroids (106 m – 237 m).

This asteroid is coming particularly close to Earth today

The closest thing to Earth today is the asteroid “(2013 UX)”. It approaches our planet at 1:08 p.m. at a distance of up to 6.4 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 an impact. About 20 percent of near-Earth asteroids are classified as potentially dangerous.
Today there is 1 potentially dangerous asteroid near Earth: “(2021 TA8)”.

(2021 TA8)
First observation: 05/31/2010
Last observation: 03.12.2021
Absolute magnitude: 21.24 mag (faint)
Estimated diameter: 150 m to 336 m
Distance: 40.4 million km
Speed: 71463.08 km/h (19.85 km/s)
Time of the shortest distance to earth: on 05/17/2022 at 18:51

5 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 5 Earth orbit cruisers are approaching our planet.

  • Apollo asteroids near Earth today: “(2013 UX)”, “(2021 TA8)”, “(2021 XE)”

  • Near Earth Aten asteroids today: “495615 (2015 PQ291)”, “(2014 TC36)”

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.
