Some SpaceTrajectories -Asteroid Apophis, Planetary Defense AndElon Musk

The asteroid is about 1,100 feet (340 meters) broad, was originated in 2004 and will make a judiciously close flyby of Earth on Friday, April 13, 2029. Apophis will not hit Earth during that flyby; more on that later. Even though, it's large and close and has a touchy name, and the internet loves its asteroids.

That is apparently how SpaceX CEO Elon Musk ended up retweeting on the post of podcaster Joe Rogan in which he expressed a story about Apophis. "Great name!" Musk tweeted. "Would not misgiving about this specific one, but a big rock will hit Earth ultimately and in current situation we have no defense."

In September, Musk and Rogan formed headlines when Musk arose on the latter's podcast for a three-hour discussion of Tesla and whether the universe is a likeness. Throughoutthat actualization, Musk notably kippered marijuana and sipped whiskey.According to The Washington Post, it is prompted by NASA review of commercial space partnerships.

It is unclear from his tweet whether Musk is referring to the asteroid's actual name, Apophis or the "God of Chaos" phraseology interpolated by the news outlet Rogan cited. The first dubbed in 2004 was Asteroid 99942, MN4 based on a formula marking it is identified and theywere given a formal name Apophis in the next year.

Musk is mostly right in his appraisal of Apophis itself. The rock is dubbed a Potentially Hazardous Asteroid for its nearly grand size and nearly close approaches, but it is a very long way from imaginably perilous to actually smash up. Asteroid experts are presuming it will not hit Earth at that time: They have measured a trajectory 7.4 miles about to 12 kilometers wide that passes thousands of miles away from our home planet during that close encounter. Scientists have also ruled out a 2036 impact.

Other space rocks could also be a barrier on that sort of time scale, but on this right now, NASA has not spotted any asteroids with worrying trajectories.  According to the website of NASA’s Planetary Defense Coordination Office, - "No known asteroid poses a compelling risk of impact with Earth over the next 100 years".
