Detecting metal flying discs flying near Earth?

UFO hunters have digged back a photo taken a year ago to prove the existence of what they call a "long, giant metal flying disc".

The flying saucer seems to be flying around an asteroid close to Earth, rather than a "small moon" as NASA claims.

In GIF images published by NASA on January 26, 2015, a spinning object is seen in the center of the black-and-white photo. Moving around it is another smaller, glowing object. A year later, "alien investigators" claimed that the asteroid had crossed Earth at the end of last month, and the small companion object was a long metal cylindrical UFO.

NASA's photo published with the caption of a large object is an asteroid, while a small spot is a moon.

In the post explaining the photo, NASA said the large object was an asteroid called 2004 BL86 , with a width of nearly 335 meters. Turning around it is a small moon with a diameter of about 230 meters.

This phenomenon is actually nothing unusual. About 16% of asteroids near Earth have a moon orbiting. Some asteroids even have 2 moons.

But is it true? UFO hunting expert Scott C.Waring skeptical. In a recent post on UFO Sightings Daily, Waring did not believe in NASA's caption and insisted that the smaller object was not the moon but a metal UFO.

In this magnified series, Waring compared the edited photos with the original.

"Below, you can see the zoomed-in, close-up image of UFOs surrounding the 2004 Asteroid BL86. This UFO is 70 meters long , " Waring wrote. "It has a long metal cylinder in the middle and two smaller pillars on either side. This UFO object is rotating, so that we can see it from many different angles."

The series of enlarged images from many angles of light show that it resembles a metal UFO, about 70 meters long.

But despite being dissatisfied with NASA's explanation of this spectacle, UFO hunters are also less likely to see the phenomenon more clearly in the near future. According to calculations, this asteroid will not cross the Earth at close distance for about 200 years.

The resolution of the image taken by radar is 4 meters / pixel. Therefore, when zoomed in, the observation is not really clear and can be controversial.
