Asteroids are located far off in space, but some of them often stray towards Earth. There are almost 1.9 million asteroids that are 1KM or larger and millions of other space rocks in space, according to NASA. The space agency keeps an eye on asteroids with its advanced ground and space-based telescopes. Moreover, NASA has recently announced its Daily Minor Planet Project where you can help the space agency spot these potentially dangerous space rocks!
Although asteroids rarely threaten Earth and most of them burn up in the atmosphere itself without causing any harm to the planet, their close approaches serve as a reminder of the importance of continuing to study and track asteroids to better understand and prepare for potential threats.
NASA has now revealed details about a humongous asteroid that is hurtling towards Earth today.
The asteroid, given the designation of Asteroid 2021 JK7, will make its closest approach to Earth today, May 22, at a distance of 6.3 million kilometers. This space rock, which is nearly the size of an aircraft with a width of 150 feet, is hurtling towards Earth at a blistering speed of 82341 kilometers per hour. It belongs to the Apollo group of Near-Earth Asteroids, as per NASA.
Surveys done by NASA-supported ground-based telescopes – including Pans-STARRS1 in Maui, Hawaii, as well as the Catalina Sky Survey near Tucson, Arizona – have identified thousands of near-Earth objects. And a space-based telescope called NEOWISE has identified hundreds of others while scanning the skies at near-infrared wavelengths of light from its polar orbit around Earth. NASA uses its ground-based radar to gather precise data about the asteroid's path and its characteristics.
