The giant Apophis asteroid invading Earth has caused a storm of panic news. Elon Musk warns that we are completely defenseless against asteroids killing planets, even if this is not a threat.
Musk responds to a tweet from his friend, podcast host Joe Rogan, who shared a news article about the so-called "God of Chaos" asteroid from Express, which seems to be releasing a new doom – a "somber article about this particular asteroid to everyone few weeks.
Great name! You won't worry about this particular one, but eventually a large rock will hit Earth and we have no protection at the moment. https://t.co/XhY8uoNNax records19459002Sense— Ilon Musk (@elonmusk) August 18, 2019
"Great name! You won't be worried about this particular one, but a big rock will hit Earth in the end and we don't have any defense at the moment, " the founder of SpaceX said.
Approximately the size of four football fields, if the space rock hits Earth, it will overwhelm us with the power of 15,000 nuclear weapons that simultaneously detonate.
However, Musk correctly warns that Apophis' entire narrative is a little overburdened: during his near-flight in 2029, the asteroid will come within 37,600 km (23,363 miles) of our planet, only one-tenth of the distance between the Earth and the Moon. Scary, but not quite apocalyptic.
The Department of Celestial Mechanics at St. Petersburg State University had previously warned that a 370-meter wide asteroid could strike Earth sometime in 2068. That is, if it somehow manages to traverse a two-meter space in space of " keychain 'during its near-flight to Earth in 2029 (a factor of about one in 2.3 million).
Although more than the breadth of the full moon will pass within one minute as it screams past Earth on April 13, 2029, the asteroid, named after the Egyptian god of evil and destruction, resides in eternal darkness, are more likely to provide a magnificent spectacle for star stars than the destruction of all life on Earth.
Of this potential harbinger of the apocalypse, NASA says that "the international asteroid research community could not be more excited" about what the agency calls "an incredible opportunity for science. ”
NASA will actually use near-flight in 2029 as an R&D opportunity to prepare our planetary defenses for which Musk is so concerned.
"By watching Apophis during its flight in 2029, we will gain important scientific knowledge that could one day be used for planetary defense," says Paul Chodas, CNEOS Director.
In fact, NASA and Musk's SpaceX are already developing their first mission to divert an asteroid to the so-called Double Asteroid Redirection Test, which will target the 65803 Didymos asteroid sometime in June 2021 using one of SpaceX's Falcon 9 rockets with $ 69 million in NASA funding.  However, NASA acknowledges that there is little chance of its being reflected on Earth; somewhere in the region of 1 in 100,000, "many decades from now" although more detailed future calculations are expected to render the asteroid harmless to our planet.
