NASA reveals two narrow asteroids 'swinging fists' into Earth

NASA's asteroid tracker at California's Jet Engine Laboratory (JPL) has revealed a spectacular escape from Earth.

NASA has just revealed two dangerous asteroids that nearly "swung their fists" into Earth, flying at tens of thousands of kilometers an hour and skimming over our love with a close distance that is almost everywhere. convenient forecasts do not estimate before the risk is out.

One of two asteroids has just made scientists scare at dawn on March 27. According to data published by JPL a few days after it passed, it could be as big as three times a two-story bus and travel at 43,450km / hour.

The asteroid, named 2019 HS2 , falls into the "near Earth NEOs" group . NEOs consist of asteroids that orbit the sun at a distance of less than 194.5 million km. Subsequent calculations showed that 2019 HS2 passed us at 1.96 million km, 5 times the distance from Earth to the Moon. The distance seems very far away, but it is dangerous enough to calculate the probability of collisions of celestial bodies, based on the consequences that a space disaster can occur.

Typically, objects with a diameter of 10 meters or less may be crushed in the upper atmosphere of the Earth, but 2019 HS2 is much larger and NASA has included it in the list of concerns.

A new spirit was also revealed by NASA after a few years of being kept private. It's about the asteroid named 2012 TC4, which NASA expects to approach Earth in October 2017 for scientists to have the opportunity to research and design planetary defense plans, as well as to do Practical test for NASA's dangerous asteroid detection and reaction system.

Scientist Vishnu Reddy, planetary defense expert at the University of Arizona, co-authored a new article about the event, said it was a really great experience to experiment with an asteroid. really.

Many telescopes and other tracking devices have been mobilized. On 2012 TC4 to Earth was expected so that after it passed, scientists fell back when calculations showed that the probability of a collision was . 1/180, extremely high for a dangerous object. dangerous. Scientists decided not to publish in a hurry because of fear of causing panic.

This shows that although there are many modern facilities, the system of detection and defense of disasters from the Earth's space is still very immature and may miss some objects. The painful evidence is that an asteroid exploded in the sky of Russia's Chelyabinsk, pouring meteorite and seismic rain into this country in 2012, causing countless losses. No space agency in the world has captured this asteroid before.

To reinforce Earth's defense strategies, NASA said it would explore and answer the question "what if an asteroid crashed into Earth in 2027?" in a simulated exercise, taking place at the upcoming 2019 Planetary Defense Conference in Maryland (USA) this week.
