With all of humanity’s telescopic eyes on the sky, it is uncommon for an asteroid to take us without warning. However that is what occurred this morning within the sky over the Philippines. Solely hours after it was detected, it burned up in a vivid flash above the island of Luzon.
NASA’s Catalina Sky Survey detected the small asteroid, now named 2024 RW1, solely hours earlier than it reached Earth’s ambiance. It was solely about one meter in diameter and posed no menace. Despite the fact that studies say it “struck the Earth,” in actuality, it solely struck the ambiance, the place objects that small expend.
A video captured from the northern tip of the Philippines reveals a flashing fireball partly obscured by clouds. The asteroid briefly created a tail, which disappeared shortly.

That is solely the ninth time that we have detected an asteroid earlier than it reached Earth, although the European House Company says {that a} one-meter asteroid hits the Earth each two weeks.
Being taken without warning by an asteroid is an uncommon feeling. However although it was a shock, it was detected earlier than it reached us. We are able to take consolation that our automated sky surveys detected such a small object. If it was giant sufficient to trigger any quantity of harm, it might’ve been brighter and we would have detected it a lot sooner.
Although this one was no hazard, that is not at all times the case. In 2013, the 18-ton near-Earth asteroid referred to as the Chelyabinsk meteor exploded over the Russian metropolis. It created intensive floor harm and brought about nearly 1500 individuals to hunt medical help, although no one was killed.
Earth has suffered way more catastrophic impacts than that all through its historical past, and that spectre haunts our civilization. The Chicxululb impression brought about a mass extinction and ended the dinosaurs. The Vredefort Crater in South Africa was excavated two billion years in the past by an impactor between 10 to fifteen km in diameter.
Nevertheless it’s not simply an asteroid’s dimension that is the issue. They strike Earth with nice velocity. The ESA says that 2024 RW1 was travelling at 17.6 kilometres per second, or 63,360 kilometres per hour, which is the typical pace for these objects.
Each NASA and the ESA actively seek for and catalogue the asteroid inhabitants. NASA additionally invitations specialists to participate in common mock workout routines. In these workout routines, groups of persons are fed common fabricated updates on the strategy of a harmful asteroid and requested to take no matter actions they see match.
2024 RW1 was no menace. The truth is, it is an attractive, pure spectacle.
Nevertheless it’s additionally a reminder that Earth is not remoted from the cosmos, although in day-to-day life, it may well appear to be it’s.
