Asteroide Apophis de 340 metros passará em 2029 a 5,9 raios da Terra, será visto por 2 bilhões e estudado por missões espaciais.

In April 2029, the Asteroid Apophis Will Make a Rare Approach to Earth, Visible to Billions, and Will Offer Unique Opportunities for Scientific Research.

The Asteroid Apophis, named after the Egyptian deity of chaos and darkness, is on a trajectory toward Earth. With a diameter of 340 meters, the celestial body will pass within 5.9 Earth radii on April 13, 2029.

Initially, scientists considered Apophis a real threat. However, after more than 20 years of astrometric and radar analysis, they dismissed any chance of collision. Still, the phenomenon generates enormous interest because an approach of this magnitude occurs, on average, once every 7,500 years.

Unprecedented Scientific Opportunity

The proximity of the asteroid will open new doors for planetary science and for Earth’s defense. The flyby will allow researchers to observe how the gravitational field and the magnetosphere influence Apophis’s trajectory and characteristics. According to Space.com, measuring these properties is essential for developing effective defense strategies against possible future threats.

A Spectacle Visible to Billions

As probes and agencies plan their part, Earth will also have a special role. Apophis will be visible to the naked eye for about two billion people, especially in regions of Africa and Western Europe.

This moment is expected to mark modern astronomy. After all, it is not common for an object of this size to pass so close without posing a risk, while still offering a rare opportunity for collective observation and learning.

A Spectacle Visible to Billions

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Heir bought 23,000 degraded acres in the Scottish Highlands, fenced the area, planted nearly 1 million native trees, and transformed empty mountains into a forest officially recognized after meeting 15 evaluation criteria over 20 years.

The Atacama Desert, the driest place on Earth, was covered in flowers and turned into a colorful carpet with more than 200 species in the phenomenon called “desert bloom,” when atypical rains awaken seeds that had remained dormant in the soil for many years.
