An enormous asteroid categorized by NASA as an almost-earth object is expected to pass through our solar system on August 29. But unlike his reputation on the news, the giant asteroid that is being speculated to ram to earth soon is not doing anything like that, NASA reassures.
The with & # 39; 2016 NF23 & # 39; The indicated asteroid is 70 meters high and 160 meters wide – a weir larger than two Airbus A380s that are placed end-to-end and as a result of flying according to a NASA with a speed of 500 kilometers per second.
While the asteroid is technically classified as one near-Earth object (NEO) in NASA & # 39; s database, such & # 39; n indication fits on every & # 39;comet& # 39; or & # 39;asteroid"That comes within 200 million kilometers of our planet.
2016 NF3 will do away with its close approach to a comfortable 4.8 million kilometers of Earth (that's about 13 moon distances), according to predictions made with "reasonably low uncertainty" by the space agency.
NASA follows a huge catalog of objects that "are affected by the attraction of nearby planets that allow them to enter the earth's neighborhood". The near-Earth objects (NEOs) that NASA keeps a close eye on are the potentially dangerous asteroids & # 39; (PHA & # 39; s) that threaten a collision with the earth.
2016 NF23 drew attention to its size, its relatively close approach to our part of the solar system and the last parameter used by astronomers and the absolute magnitude & # 39; is called – a measure of the brightness of an object when it is observed from a standard vantage point. The absolute magnitude of 2016 NF23 is 22.9 – just about dim enough to prevent scientists from sending out alarms and adapting to a Armageddon.
There are others that come much closer, for example the PU23 from 2018 – a small asteroid of about 6 meters in diameter that passes on 8 August at 8 moon distances (distance between the earth and the moon).
A second visit to NEO – and one that NASA has seen for the first time since its discovery in 1998 – is the suggestive name '1998 SD9 & # 39 ;, which is expected to come much closer from 4 moon intervals away.
An extra security comes from a NASA pronunciation updated late last year: "It is predicted that no asteroid currently known will affect the Earth for the next 100 years."
The space agency has drawn up a plan to protect the planet against objects that threaten the impact after our close encounter with the football field asteroid 2018 GE3 earlier this year. They call it "National Near-Earth Object Preparedness strategy and action plan"It goes into five strategies, including better detection and tracking of NEOs, technologies to deflect a PHA, improve models and make predictions about NEO & # 39; s, cooperation and emergency plans for NEO & # 39; s at international level, and stricter procedures for an inevitable effect.
Rest assured, NASA does not quickly warn of a collision between endless collisions between the asteroids.
