Could quasi-moon 2025 PN7 be of technological origin? Scientists raise doubt

Earth’s quiet companion, 2023 FW13, has circled with our planet for decades - yet almost no one knew it existed. Why does a tiny object follow us through space? The answer might surprise you.  Know the mystery behind this hidden quasi-moon.

'Since 60 years': What is Quasi-Moon and why is it silently orbiting Earth?

In a stunning discovery, scientists&nbsp;have spotted an asteroid which is tagging along with Earth in its annual revolution around the Sun.&nbsp;

The asteroid, which has been dubbed as 2023 FW13, has been termed a “quasi-moon” or “quasi-satellite" by the experts.

The asteroid has been classified as a "quasi-moon" because it has been orbiting the sun in a similar time frame as the Earth. However, the asteroid was also impacted by Earth's gravitational pull.

Asteroid 2023 FW13&nbsp;measures nearly 50 feet (15 meters) in diameter and is located at a distance of nearly nine million miles (14 million kilometres) from the Earth.

The scientists used the&nbsp;Pan-STARRS&nbsp;survey telescope for spotting the 2023 FW13 on March 28, 2023.&nbsp;

The telescope was kept on the top of Haleakala, which is a dormant volcano on the Hawaiian Island of Maui.&nbsp;

The&nbsp;Canada-France-Hawaii telescope as well as two observatories in Arizona (which are the&nbsp;Kitt Peak National Observatory&nbsp;and&nbsp;Mt. Lemmon SkyCenter) confirmed the asteroid's presence in the Earth’s vicinity.

The asteroid was officially listed by the&nbsp;Minor Planet Center&nbsp;at the International Astronomical Union on April 1. The organisation is responsible for designating new moons, planets as well as other astronomical objects in our solar system.

<h2>How asteroid 2023 FW13 was classified as a 'quasi-moon'?</h2>

The listing of the asteroid came to the attention of journalist and astronomer Adrien Coffinet. He used an orbit simulator to map the path of the asteroid. The orbit simulator was developed by amateur astronomer Tony Dunn.&nbsp;

In the model, 2023 FW13 was seen revolving around the sun at the same time as the Earth does. Since the asteroid circles around our planet hence, Coffinet classified it as a “quasi-moon".

Senior research scientist at the&nbsp;Space Science Institute&nbsp;in Boulder, Colorado Alan Harris emphasised that since the Earth plays an important role in the motion of the asteroid, its classification as a “quasi-satellite” is a little far-fetched.

According to the scientists, 2023 FW13 appears to be the cosmic companion of our planet since at least 100 BCE.&nbsp;

The asteroid is most likely to follow our planet in its orbit around the sun till around 3,700 CE. “It seems to be the longest quasi-satellite of Earth known to date,” said Coffinet.

The asteroid, even though hovers relatively close to our planet, is unlikely to collide with the Earth.

“The good news is, such an orbit doesn’t result in an impacting trajectory ‘out of the blue,’” said Harris.

Earth gets another 'moon'. This 'quasi-satellite' to lurk around for thousands of years

Astronomers have discovered a "quasi-moon" — an asteroid that orbits the Earth but is actually gravitationally bound by the Sun. It is called 2023 FW13 and was spotted recently, causing a stir among space enthusiasts.&nbsp;

Experts&nbsp;used the Pan-STARRS telescope at the top of the Haleakala volcano in Hawaii to observe the space rock which has been labelled a quasi-moon.&nbsp;

Sky and Telescope's report has mentioned that experts believe that it has been orbiting Earth since 100 BC and will continue to do so for at least another 1,500 years.&nbsp;

If all calculations are correct (or close to correct) then 2023 FW13 would be the most stable Earth-like quasi-satellite ever discovered.&nbsp;
