NASA: A Dangerous Asteroid Will “Grab” Earth This Week



These so-called “near-Earth objects” (NEOs) must cross a certain threshold to be considered “potentially dangerous,” Metro reports.

And experts from the US space agency say there is such a rock on the radar for this week. The asteroid 2012 XA133 is set to cross Earth on Thursday, March 26 at a speed of 53,000 mph.



The asteroid measures approximately 1,280 meters (390m) wide, which is enough to cause a major impact on Earth if it collides with the planet.

It is believed to pass 0.04453 astronomical units (AU) or approximately 4.1 million miles from Earth's center. A single AU describes the distance from Earth to the sun, approximately 93 million miles. “While orbiting the Sun, NEOs can sometimes get close to Earth,” Nasa explained.

“The potentially dangerous asteroids (PHAs) are currently being determined based on parameters that measure the asteroid's potential to make near-Earth-threatening approaches,” Nasa said in a statement.

Most of the smallest interplanetary particles that reach the surface of the Earth are small dust particles, which are released by comets as their oils evaporate in the solar neighborhood.

“Much of the largest interplanetary material that reaches the Earth's surface as fragments of asteroids colliding into one another.”

The agency goes into some detail about what would happen if one of these rocks ended up crashing inside us.

With an average interval of about 10,000 years, rock or iron asteroids larger than about 100 meters would be expected to reach the Earth's surface and cause local disasters or produce tidal waves that could overturn low-lying coastal areas.

Since their orbital paths often cross that of the Earth, collisions with objects near the Earth have occurred in the past, and we must remain alert to the possibility of Earth's near future.

It seems prudent to make efforts to discover and study these objects, to characterize their sizes, compositions, and structures, and to keep an eye on their future trajectories.
