NASA tracking bus-sized asteroid making close approach to Earth TOMORROW

NASA is keeping a adjacent oculus connected a bus-sized asteroid that is expected to skim past Earth Saturday astatine a region lone somewhat begetter distant than the moon.

Officials astatine the abstraction agency's Jet Propulsion Laboratory (JPL) and and Center for Near-Earth Object Studies (CNEOS) estimated that the abstraction stone is betwixt 28 and 62 feet wide, and volition sprout past our satellite astatine a velocity of roughly 29,300 mph.

It volition travel within 273,000 miles of Earth. By comparison, the mean region betwixt our satellite and the moon is roughly 238,900 miles.

The adjacent encounter is expected to instrumentality spot successful the aboriginal greeting hours, but the asteroid poses nary menace to Earth.

The abstraction rock, called 2024 VK3, is conscionable 1 of 5 asteroids that volition alert by our satellite this weekend. 

Three are arsenic astir large arsenic commercialized airplanes and 1 is astir the size of a house, according to NASA JPL. 

The next-closest brushwood volition beryllium made by the airplane-sized asteroid 2024 VZ2, which volition travel within 790,000 miles of our planet. 

The others volition support distances of implicit a cardinal miles distant with house-sized asteroid 2024 UC5 being 2,580,000 miles distant astatine its closest constituent to Earth. 

All of these asteroids are considered Near Earth Objects (NEOs) due to the fact that they are wrong astir 30 cardinal miles of our planet. 

NASA has observed, documented and classified astir 36,000 objects successful the star strategy arsenic NEOs.

The abstraction bureau tracks NEOs chiefly to place asteroids that could perchance collide with Earth, and measure the menace they pose.

NASA uses a assortment of methods to survey adjacent abstraction rocks, including some ground-based and space-based telescopes.

One cardinal instrumentality is the Near-Earth Object Surveyor, an infrared abstraction scope utilized to observe and qualify Potentially Hazardous Asteroids (PHAs).

PHAs are asteroids that person a precocious probability of making a adjacent attack to Earth and are ample capable to origin important harm if they made impact. 

Technically, that means immoderate abstraction stone that comes within 0.05 astronomical units - oregon roughly 4,647,790 miles - of Earth's orbit, and has an implicit brightness of 22.0 oregon less. 

Absolute brightness is an indirect measurement of an asteroid's size. Lower values of magnitude bespeak greater brightness, and frankincense larger objects. 

None of the asteroids that volition alert by Earth this play are considered PHAs.

But NASA is preparing for the improbable lawsuit that a PHA hurtles towards our satellite successful the future.

The agency's Planetary Defense Coordination Office (PDCO) is processing technologies and strategies that could harmless Earth from a catastrophic asteroid impact. 

Established successful 2016, PDCO is tasked with the ngo of finding, tracking and amended knowing asteroids and comets that could airs an interaction hazard to Earth. 

In 2021, the bureau launched the Double Asteroid Redirection Test (DART), which slammed a spacecraft into the asteroid Dimorphos and successfully changed the abstraction rock's orbital trajectory. 

This ngo was a trial of the 'kinetic impact' asteroid deflection strategy, which could 1 time beryllium utilized to redirect a PHA connected a collision people with Earth. 

In October, the European Space Agency launched the 2nd signifier of this mission, called Hera.

The Hera spacecraft is presently connected its mode to Dimorphos to perform a elaborate post-impact survey of Dimorphos. This volition assistance experts solidify kinetic interaction into a well-understood and repeatable planetary defence technique.
