no need to fear them
If we refer to the fact that on an average, an asteroid of four meters in diameter collides with the Earth every year and an asteroid of eight meters in diameter collides with the Earth every five years, then asteroids of this size fragment into meteorites and some reach the Earth in the form of meteorites. Now 2023 BU has been discovered and its orbit around the Sun has been predicted and future approaches to Earth can already be predicted. It is estimated that between the years 2077 to 2123, there is a possibility of it affecting the earth once in 10,000. So we need not be afraid of 2023 BU or millions of such objects in the Solar System.
An asteroid impact of more than 25 meters in diameter would have to occur to significantly affect life on Earth and at least one kilometer in diameter to challenge existing civilization. According to an estimate, the number of such asteroids in our solar system is slightly more than a thousand and they can affect the Earth once every five million years. We know of more than 95 percent of these asteroids.
Could asteroids pass closer? 2023 BU is the fourth asteroid ever recorded so close to Earth. Earlier, three small asteroids passed very close to the Earth in the years 2020 and 2021 (2021UA, 2020 QG and 2020VT) which were discovered.
this happens often
Asteroid 2023 BU and numerous other asteroids have passed close to Earth during our solar system’s five billion years of existence and will continue to do so in the future. What has changed in recent years is that we can identify asteroids of these sizes and assess the hazards they pose. An asteroid roughly five meters in diameter was discovered thousands of kilometers away by an amateur astronomer, showing that the technology needed in astronomical exploration has reached the masses. This is very encouraging.
changed direction
Amateur researchers and professionals can work together to continuously search and categorize threats to analyze them. Another exciting development came to light last year when the Double Asteroid Redirection (DART) mission successfully deflected a spacecraft from an asteroid collision. DART reinforces the idea of deflecting an asteroid when it is in serious danger of hitting Earth.
