Khaberni - On July 5, 1997, NASA's Near Earth Object "NEAT" project at the Haleakala Observatory in Hawaii detected a small object moving between the stars, which was later named "1997 NC1"
At the time, this discovery was just another addition to the thousands of known asteroids, but orbital calculations revealed that this object would return in June 2026 to present one of the most significant safe approaches of a large asteroid to Earth in recent decades.
Today, June 27, 2026, the asteroid will pass at a distance of about 2.56 million kilometers, which is about 6.7 times the distance between Earth and the Moon. This is astronomically close but completely safe, as confirmed by NASA and the European Space Agency, with no chance of it colliding with Earth. This is the closest pass since before the year 1600, and it will not approach this distance again until the year 2133.
Why does this asteroid receive so much attention?
The asteroid "1997 NC1" is classified among the Earth-close "Aten" asteroids, which are categorized as "potentially hazardous asteroids". This designation might alarm non-specialists, but it does not mean an imminent impact is expected, it only indicates that its orbit comes close enough to Earth's orbit to warrant ongoing monitoring.
Estimates of its diameter range between 750 and 1600 meters, making it larger than most known near-Earth asteroids.
It moves at a speed approaching 8.9 kilometers per second, over 32,000 kilometers per hour, fast enough to travel the distance between Doha and Cairo in less than a minute if it were moving within the atmosphere, but such speeds are typical for bodies orbiting the sun.
The importance of the event lies not just in the asteroid's passage, but also in the possibility of observing it, as its brightness could reach about the tenth magnitude, making it beyond the limits of naked eye visibility but an appropriate target for small telescopes and large astronomical binoculars.
During these days, it appears in the area between the constellations Ophiuchus and Serpens Cauda, and amateurs can observe its true movement among the stars in just minutes, as it visually moves about 40 arcseconds per minute, and therefore it will not appear as a fixed star, but as a slowly creeping point of light against the backdrop of the sky, a rare sight not often repeated with large objects.
NASA radars reveal a new surprise
This passage represents the first real opportunity to observe the asteroid by radar, so NASA's Deep Space Network used the Goldstone antennas in the Mojave Desert in California in an attempt to determine its actual shape, after years of conflicting estimates about its size, composition, and reflectivity.
The preliminary findings from the observation, announced on June 25, indicated that the asteroid rotates slowly and consists of two connected lobes, while it appears to be less than one kilometer in diameter, which helps scientists to resolve previous contradictions between measurements by the Spitzer telescope and the "NEOWISE" mission and spectroscopic observation.
NASA's Jet Propulsion Laboratory asteroid scientist "Lance Benner" stated that these observations would also help improve the calibration of previous measurements and understand the physical properties of the asteroid more accurately.
A rock older than Earth itself
The significance of "1997 NC1" lies not only in its proximity but also in its age, as this asteroid is preserved remnants of the material from which the solar system formed over 4.5 billion years ago, before Earth appeared in its current form, and long before the existence of oceans and life.
Therefore, scientists look at such objects as "cosmic fossils", as they retain components that are almost as they were at the dawn of the solar system.
Although the asteroid poses no danger to Earth in this passage, studying it helps scientists to improve planetary defense systems, to understand how planets are formed, and to prepare for any objects that might pose a real threat in the future.
Every time an ancient object like this passes close to Earth, we are reminded that our planet is not isolated in the universe, but lives within a celestial system pulsating with movement for billions of years.
What appears today as just a point of light moving between the stars may carry within it a silent record of the beginnings of the solar system. Therefore, observing these bodies is motivated not by fear, but by the scientific curiosity that has always led humans to a deeper understanding of our place in this vast universe.
