The first asteroid that has come this near to Earth in human knowledge is Apophis.
The name for this asteroid, Apophis, comes from the Egyptian demon sometimes described as the demon of chaos and devastation. Its closest approach will be that of the first known asteroid of this size passing between Earth’s geostationary satellites and the Atlantic Ocean.
where would apophis hit earth
Apophis is a large asteroid scheduled to pass Earth safely Friday, April 13, 2029. About 375 meters across, this asteroid is rather large; 90% of space rocks are smaller than it.
Its closest approach will be that of the first known asteroid of this size passing between Earth’s geostationary satellites and the Atlantic Ocean.
One can see this asteroid flying past Earth from the Atlantic, Europe, Africa, and Asia if the sky remain clear for the passing period. Apophis is the name of an asteroid derived from the Egyptian monster occasionally referred to as the demon of anarchy and destruction.
Astronomers at Kitt Peak National Observatory found asteroid 99942 Apophis on June 19, 2004; they stated that the asteroid is of S-type form, circles lasting 324 days, and keeps returning every few decades near to Earth.
Published by Cambridge University Press, a research article estimated the likelihood of asteroids impacting the future on Earth might be around 2029, 2036, or 2068.
Closely observing this event will be the NASA spacecraft OSIRIS-Apophis Explorer (OSIRIS-APEX). This spacecraft resembles that of the 2020 Asteroid Bennu probe exactly. Observing this asteroid will cost NASA $200 million, hence their goal is rather low. OSIRis-APEX will circle Apophis as it passes Earth in 2029 for eighteen months.
By means of spacecraft, scientific research of Apophis in 2029 will offer insightful analysis of how an ancient remnant of the early solar system reacts to gravitational force
s. For next generations on Earth, these revelations will be absolutely vital.
