With “468910 (2014 KQ76)” – in addition to 15 other asteroids – 1 potentially dangerous asteroid reaches its closest point in its orbit to Earth today. An overview of the currently largest asteroids near Earth and potential hazards.

NASA is currently aware of over 1.1 million asteroids. Every month, thousands of new rock bodies are discovered, usually irregularly shaped. Particular 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 approach the Earth’s orbit and therefore can also be dangerous for the blue planet. This article provides an overview of all near-Earth asteroids that are passing their closest point in their orbit today.
On Monday, April 18, 2022, a total of 16 asteroids will approach their nearest station during the day, including 1 potentially more dangerous. asteroid.
The largest near-Earth asteroids to date
“450143 (1999 ED5)” With an estimated diameter of 309 to 692 meters, it is currently the largest asteroid near Earth. 450143 (1999 ED5) makes its closest approach to Earth at 04:39 today. Second largest near-Earth asteroid “(2016 TS92)” and has an estimated diameter of 245 to 547 meters. “(2019 SW8)” today it ranks 3rd among the largest near-Earth asteroids (202 m – 451 m).
Today this asteroid is approaching the Earth especially close
The closest asteroid to Earth today is “(2022 FY4)”. It approaches our planet at 07:53 at a distance of up to 1.5 million km.
The closest asteroid approached us without colliding with the Earth – “(2020 QG)”. On August 16, 2020, it flew past the Earth at a speed of about 44,000 km/h, only 3,000 km from the Earth. Arriving from the direction of the sun, the experts did not notice its approach: it was noticed only 6 hours after the flight. It probably wouldn’t have done much damage to the Earth even if it had collided. Due to its small size, only 3 to 6 meters in diameter, it is speculated that it would burn up in the atmosphere if it got any closer.
Potentially dangerous asteroids near Earth today
Potentially dangerous asteroids are those asteroids that come closer than 0.05 AU. (about 7.5 million km) and have an absolute brightness of 22 stars. Therefore, they are considered large enough (at least about 140 m in diameter) to cause significant damage in the event of an impact. About 20 percent of near-Earth asteroids are classified as potentially hazardous.
Today, there is 1 potentially dangerous asteroid near the Earth: “468910 (2014 KQ76)”.
468910 (2014 KQ76)
First observation: 07/18/2002
Last observation: 05/20/2021
Absolute value: 21.65 (weak)
Estimated diameter: from 124 m to 278 m.
Distance: 14.7 million km
Speed: 50719.25 km/h (14.09 km/s)
Time of the smallest distance to the ground: 04/18/2022 at 21:59
14 Earth cruisers near Earth
Asteroids that cross the Earth’s orbit are also called orbital cruisers. Earth-type asteroids Apollo cross the Earth’s orbit from the outside, near-Earth-type asteroids Aten cross the earth’s orbit from the inside. Today, a total of 14 near-Earth cruisers are approaching our planet.
Apollo asteroids near Earth today: “450143 (1999 ED5)”, “468910 (2014 KQ76)”, “(2015 GZ5)”, “(2016 TS92)”, “(2016 WU2)”, “(2018 KS)”, “(2019 SV8)”, “(2020 BD11)”, “(2020 TQ6)”, “(2021 JV5)”, “(2022 FG2)”, “(2022 GJ4)”
near-Earth asteroids Aton today: “(2008 EP)”, “(2021 US2)”
Asteroids like Amor and Atira do not cross the Earth’s orbit. While it’s hard to find Atira-Asteroids are fully orbiting the Earth, approaching asteroids like Amur earth orbit outside.
