“Two million times” Beirut explosion … Fear of “catastrophic” asteroid colliding with Earth



"Two million times" Beirut explosion ... Fear of "catastrophic" asteroid colliding with Earth

More than a billion tons of TNT and two million times more explosive energy than the energy left over from the Beirut port explosion. This could happen if an asteroid of interest to NASA collides with Earth, which has been confirmed by scientific research and the work of the U.S. Space Agency.

The asteroid “Pennu” landed on its surface, last year, NASA’s “Osiris Rex” spacecraft and samples were taken from it, and a team of scientists associated with the company examined some data found by the spacecraft “threat” to the asteroid last year. In the coming centuries.

Asteroids are rocky bodies with diameters ranging from a few meters to several kilometers, and the largest bodies are called dwarf planets, the largest of which are planets.

Pennu is classified as a “dangerous asteroid”, meaning that in this case the asteroid is more than 140 meters wide and could theoretically come close to 4.65 million miles from Earth. Penn is second on NASA’s record of 72 particles close to Earth.

The asteroid, which is dark in color and resembles a large oak tree, is about 334 million kilometers from Earth and its width is 500 meters. On its rough surface there are large and dangerous rocks.

Scientists say that, like other asteroids, it formed in the early stages of our solar system and may have traces of the origin of life on Earth.

It is the same distance from the Earth as the Sun, and is believed to be rich in minute organic molecules that make up an important component of carbon, and that these asteroids, which came from the early days of the solar system, may contain water, which is another important element in the evolution of life.

Scientists believe that meteorites and comets that collided with Earth in the early stages provided the organic compounds and water needed for life on the planet, and nuclear analysis of samples taken from the asteroid “Pennu” can provide important evidence to prove this hypothesis.

National Geographic Magazine I have released a report on the impact of this rock group on Earth, indicating that in light of recent studies conducted around it, the asteroid is more likely than it is ever to affect our planet in the next 300 years. Let’s start at the end of this century.

The report focused on a new study published in the journal Icarus, which relied on data from the Osiris Rex study, and the team conducted “accurate” calculations of the orbit of the pen and indicated the extent of its proximity to Earth in the future.

Researchers led by David Fornocia of NASA’s Jet Propulsion Laboratory analyzed the risk of collisions now and between 2300, and by 2135, the Penn will reach a distance of about 123,000 miles from the Earth’s surface, and the probability of a collision will occur. Future conflicts over the next three centuries will be from 1 to 1750, which is slightly higher than previous estimates.

University of Arizona planetary scientist Dante Loretta, OSIRIS Rex chief researcher and senior author of the study, said that Pennu is the best asteroid in the solar system … we know it will be more than 100 years into the future.

Amy Meinser, a planetary scientist at the University of Arizona and an expert on non-Earth asteroids, said the team had “made a very accurate measurement”.

The team observed the impact of the sun on the motion of the asteroid “Yarkovsky”, which refers to the heat emitted by the sun in the path of the planet, which includes an increased threat to its motion in the solar system. Sunlight occurs when the surface of the “pen” heats up, while the surface of the pen returns to the sun. The asteroid releases this energy during the cooling process, which is an impetus for the asteroid in its path.

Despite these terrifying scenarios, National Geographic, the dangers posed by Penn should not disturb our sleep because within the next three centuries it will not hit the planet 99.9 percent, and any collision with the Earth will cause as much devastation as Earth. “SexySulab.” The effect led to the extinction of the dinosaurs 66 million years ago, and the asteroid was six miles wide, while the width of the “penno” was less than half a mile.

However, the collision with Penn is expected to cause catastrophic release of more than 1.1 billion tons of TNT, two million times the energy of the August 4, 2020 Beirut port explosion.

Furthermore, National Geographic suggests that future space travel may help reconsider the city’s potential.

Humanity has been monitoring the dangers of “Pennu” on Earth for more than a century, and aerospace companies are already experimenting with some practices and techniques that will help correct its course if necessary and “neutralize” this asteroid if necessary.

The report refers to the US agency’s “DART” spacecraft, which will collide with a small moon orbiting near the Earth next year, aimed at changing the moon’s orbit.
