Asteroid Apophis has not been a threat to Earth, NASA says

The National Aeronautics and Space Administration (NASA) has decided that there may be an event that threatens the earth in 2068. It was discovered in 2004 that it was named after the Egyptian god of chaos, the asteroid 99942 Apophis had previously been predicted to pass unnoticed by Earth. However, a new set of data and analysis suggests that the asteroid has not been a threat to Earth for at least 100 years.

New information emerged when astronomers used flybyid’s flyby on March 5, 2021, as an opportunity to use radar detection to measure the orbit of a celestial object orbiting the Sun.

“The impact of 2068 is no longer possible, and our statistics do not indicate a risk for the next 100 years,” David Farnocchia of the NASA Center for Near-Earth Object Studies (CNEOS) said in a NASA statement. .

“With the support of recent optical tests and further radar testing, the uncertainty in Apophis’ orbit has dropped from hundreds of miles to a few kilometers in anticipation by 2029. future movements, so now we can remove Apophis from the danger list. ”

Farnocchia says this “risk list” is the Sentry Impact Risk Table maintained by CNEOS, which includes all asteroids with orbits close to Earth.

To track Apophis’ movements, astronomers have used a 70-bart Deep Space Network radio antenna at the Goldstone Deep Space Communications Complex near Barstow, California. They also used the Green Bank Telescope 100-meter telescope in West Virginia to show the release of Apophis. Both systems were used together in double-bistatic “bistatic” tests.

The radar images of Apophis may appear as pixelated but one pixel covers 38.75 meters which is impressive considering the asteroid is 17 million miles away from Earth. In addition to the asteroid cycle, astronomers also hope to study its position through continuous analysis. An asteroid with a diameter of 200 meters is expected to look like a peacock, like most asteroids of this size.

The next plane crash past Earth is estimated to have occurred on April 23, 2029. It will be 32,000 miles from the surface of our planet and will be visible from the northern hemisphere of the Eastern Hemisphere. Before that happens, astronomers want to understand the degree of rotation and the orbit around it. This will help them to understand how it will react to the Earth’s crust that could cause an asteroid earthquake.
