Physicist Maxime Devogèle, University of Central Florida Results of calculations revealed the trajectory and impact of asteroid 2024 BX1 that exploded above the atmosphere of Berlin. Germany on January 21, as the fastest rotating asteroid ever discovered. Using a speed of 2.6 seconds and using a forward speed of 50,000 kilometers per hour. The results of this calculation were supported by data from the European Space Agency (ESA) and were published in the academic archive arXiv on April 5.
Usually, it can be difficult to detect small asteroids heading for Earth at high speeds. and most of them are found shortly before the accident. However, scientists can use the orbital data and photographs to calculate the historical identification of asteroids.
Asteroid 2024 BX1 was discovered by Hungarian astronomer Krisztián Sárneczky using the Konkoly Observatory in the Mátra mountain range, Hungary, on January 20, before impacting and exploding in Earth’s atmosphere for about 1 day The structure of the asteroid is approx. on 1 meter in diameter the explosion in the atmosphere, it was found that there was no negative impact on the Earth.
A technique used to calculate the rotational speed of an asteroid. The researchers used this to adjust the aperture of the telescope in the observatory. To clearly see the position of the stars in the background image and allow the asteroid to move across the image appears as a light trail. Afterwards, the images were analyzed to compare the light of the asteroid. In the background, the position of various stars can be seen.
The record holder for the fastest rotating asteroid ever discovered is an asteroid named 2020 HS7 that was discovered in 2020. Scientists calculated that it has a rotation speed of 2.99 seconds per revolution, with a diameter of 4-8 meters or slightly larger than asteroid 2024 BX1 .
Scientists say that the rotation of asteroids is caused by several factors, such as being pushed by collisions with smaller asteroids. Smaller asteroids have a greater chance of moving faster than larger asteroids. In addition to asteroid 2024 BX1, the physicist Maxime Devogèle has further studied and calculated the rotation of two other asteroids, 2023 CX1 and 2024 EF.
