The object was then provisionally designated 2021 PH 27 by the Minor Planet Center and announced on 21 August 2021. [1] Even in April 2021, the asteroid was never more than 45 degrees from the Sun. [11] Precovery observations of 2021 PH 27 were found in archival Dark Energy Survey images from 16 July 2017. These observations were published by ...

A small asteroid was visible in northern Siberia on Tuesday, as it closed in on its collision course with Earth. The European Space Agency issued an alert for the 27-inch asteroid at 4:27 a.m. ET ...
2024 RW 1, previously known under its provisional designation CAQTDL2, [5] was a 1-meter-sized asteroid or meteoroid that struck the Earth's atmosphere and burned up harmlessly on September 5, 2024, at around 12:40 a.m. PHT (September 4, 16:40 UTC) above the western Pacific Ocean near Cagayan, Philippines.
One, dubbed 2024 BX1 and measuring about a metre across, burned up over Berlin in January and the other, labelled 2024 RW1, caused a spectacular fireball over the Philippines in September.
Dubbed 2024 YR4, the asteroid was first spotted on December 27, 2024, by the El Sauce Observatory in Chile. Based on its brightness, astronomers estimate it is between 130 and 300 feet wide.
The head of planetary defense at the European Space Agency discusses 2024 YR4, an asteroid with a small chance of striking Earth eight years from now. Key facts about asteroid that could hit Earth ...
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
