Asteroid Apophis 99942 to come closer to Earth than even satellites

3 min read


Despite the fact that asteroids often make near techniques to Earth, this transpires at comparatively safe distances of thousands and thousands of kilometers. But this does not indicate no asteroid is at any time going to strike Earth. NASA and other room organizations have stored a watchful eye on a individual asteroid which was previously envisioned to strike Earth. Although it has now been identified it will not crash to the planet’s surface area, it will make an incredibly close tactic this 10 years, supplying scientists a opportunity to research it.

This is Asteroid Apophis 99942 and has been presented the designation Asteroid 2004 MN4 by NASA’s Middle for In the vicinity of-Earth Item Scientific studies. In accordance to NASA, Asteroid 99942 Apophis will make an extremely close excursion to Earth on April 13, 2029. On that working day, this house rock will come as near as 38000 kilometers of Earth’s surface. This is nearer than several geostationary satellites orbiting the world. It will do so travelling at an approximate velocity of 26712 kilometers for every hour, which is virtually two times as speedy as a hypersonic ballistic missile!

Former Earth ways

What’s stunning is this asteroid manufactured its past near strategy with Earth just two a long time ago! Back in 2021, 99942 Apophis handed Earth at a fairly safe length of 1.9 million kilometers. When this asteroid was identified in 2004, it was recognized as 1 of the most hazardous asteroids that could influence Earth thanks to its humongous dimension and width of somewhere around 1100 feet, earning it nearly as major as a skyscraper!

Will it ever impression?

The asteroid’s possibility of potential influence in 2029 was ruled out by researchers, although 2036 and 2068 impacts remained a be concerned. The asteroid’s 2021 excursion to Earth proved valuable for scientists as they used highly effective radar observations to thoroughly research the asteroid’s orbit and trajectory.

In accordance to Davide Farnocchia of NASA’s Center for Around-Earth Object Experiments, “A 2068 impression is not in the realm of likelihood anymore, and our calculations you should not demonstrate any impact chance for at minimum the up coming 100 yrs.” Hence, it has been declared that Asteroid 99942 Apophis is not envisioned to impression Earth’s area for at minimum a century.


Resource link On 06 April 2021, scientists discovered that the asteroid Apophis 99942 will come closer to Earth than even satellites, making it the closest fly-by of an asteroid ever recorded.

Apophis is an asteroid approximately the size of two-and-a-half soccer fields, and is classified as a potentially hazardous object due to its size and its proximity to Earth. Apophis will pass within 21,240 miles of Earth on Friday, 06 April 2029. NASA astronomer Dr. Davide Farnocchia said that this would mark the closest asteroid fly-by to date.

Current satellite systems and technology aboard the International Space Station are designed to parallel or exceed the fly-by of Apophis. The closest satellite to Earth is currently the Deep Space Climate Observatory (DSCOVR), which orbits at a distance of 1.7 million miles. Apophis’ close fly-by will mark the only time an asteroid has come closer to Earth than a satellite.

Apophis’ size and trajectory have caused some concern. Dr. Farnocchia said that while “there is no concern whatsoever regarding any impact hazard for the foreseeable future, Apophis’ close approach in 2029 will enable unprecedented observations.”

The observations made of Apophis in 2029 will be a significant addition to planetary astronomy and asteroid science research. While scientists are not expecting any significant damage from the asteroid, the close fly-by will provide a unique chance to study the asteroid, its composition and its orbit more clearly.

In November 2029, Apophis will pass Earth again, however this pass will be much farther away, at a distance of 14.1 million miles.

Apophis’ closest approach in 2029 provides an exciting opportunity to study the asteroid in detail and contribute to our understanding of asteroids and their effects on our planet. It is a reminder that asteroids and their relationship to Earth are constantly in flux and that we need to remain vigilant in monitoring the skies for potential rogue objects.
