Near-Earth asteroids today: When will asteroids be near Earth?

NASA is currently aware of the existence of more than 1.1 million asteroids. Thousands more are discovered each month. 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 to our planet. In this article we give you an overview of all the near-Earth asteroids that pass the closest point in their orbit today.
On Tuesday, January 31, 2023, a total of 26 asteroids will reach their closest station during the day, including one potentially dangerous one. asteroid.

The largest asteroids close to Earth today

“86829 (2000 GR146)” With an estimated diameter of 1805 to 4037 meters, it is currently the largest near-Earth asteroid. “86829 (2000 GR146)” makes its closest approach to Earth at 06:31 today. It is the second largest near-Earth asteroid (2021 VR3) Its diameter is estimated from 655 to 1466 meters. (2022 YM5) Today it ranks third among the largest near-Earth asteroids (217 m – 486 m).

This asteroid is particularly close to Earth today

The closest thing to Earth today is an asteroid (2023 BQ2). It will approach our planet at 11:21 pm at a distance of 2.2 million km.
The asteroid closest to us so far without hitting Earth was “(2020 QG).” On August 16, 2020, it flew over the Earth at a speed of about 44,000 km/h, just 3,000 km away. Coming from the direction of the sun, experts didn’t see it coming: It was spotted just 6 hours after it flew by. It probably wouldn’t have caused much damage on the ground even if it had crashed. Due to its small size, only 3 to 6 meters in diameter, it is assumed that it would have burned up in the atmosphere if it had come close.

Potentially dangerous asteroids near Earth today

The potentially dangerous asteroids are those that are close to 0.05 AU (about 7.5 million km) and have an absolute brightness of 22 mag or less. It is therefore considered large enough (at least about 140 meters in diameter) to cause significant damage in the event of a collision. About 20 percent of near-Earth asteroids are classified as hazardous.
Today there is only one potentially dangerous asteroid near Earth: “(2022 YB4)”.

(2022 YB4)
The first note: 12/23/2020 AD

The time of the shortest distance on Earth: on January 31, 2023 at 5:29 p.m

15 cruisers orbit near the Earth

Asteroids that cross Earth’s orbit are also called orbit cruisers. Asteroids of the near-Earth type Apollo Crossing the Earth’s orbit from the outside, asteroids of the near-Earth type I come Crossing the Earth’s orbit from the inside. Today, a total of 15 cruisers in Earth orbit are approaching our planet.

• Apollo asteroids near Earth today: “86829 (2000 GR146)”, “(2008 CK70)”, “(2016 TL18)”, “(2019 CY1)”, “(2021 GX7)”, “(2022 CY2)”, “(2022 YB4)”, “(2023 AS1)”, “(2023 AU1)”, “(2023 AE2)”, “(2023 BU1)”, “(2023 BQ2)”

• Today’s near-Earth asteroids: “(2013 DL1)”, “(2021 RW6)”, “(2023 BA4)”

Asteroids of the Amur and Atera types do not cross Earth’s orbit. While it is difficult to detect AteraAsteroids move entirely within Earth’s orbit, and are approaching asteroids Cupid Earth’s orbit from the outside.

• Near Earth Amur asteroids today: “225312 (1996 XB27)”, “459200 (2012 DK61)”, “(2003 BN4)”, “(2011 BO40)”, “(2015 VX)”, “(2017 BN3)” “,”(2017 VD14)”,”(2022 SG4)”,”(2022 YM5)”,”(2023 BG5)”
