html On August 27, a fireball-like flying object appeared in the sky above Nanchang, Jiangxi Province. It seemed to be dragging a long tail and flying rapidly in the sky. So, what exactly is this UFO (UFO)? Could it be that our country's "aerospace plane" has returned to Earth?

Regarding UFOs, there are nothing more than the following possibilities: natural phenomena, such as meteors, comets, ball lightning; man-made objects, such as various aircraft, sounding balloons, spacecraft or rocket debris re-entering the atmosphere; There is another thing that many people probably want to see, and that is an alien spacecraft.

The UFO that appeared in Nanchang this time dragged a long tail and really looked like a comet. Although the appearance is somewhat similar, the problem is that this UFO is flying quickly and does not match the characteristics of a comet.

comets are actually "dirty snowballs" made of rock, dust and ice. The orbits of comets are usually highly eccentric, meaning their orbits are very flat ellipses. When the comet gradually approaches the sun and moves near the perihelion, the sunlight shining on the comet will cause a large amount of ice and other volatiles on it to evaporate, thus forming a long tail, namely comet tail .

Speaking of comets, the most famous one may be Halley's Comet , but its last return dates back to 1986. Now it has moved away from the sun and has become very dim. We cannot see it with the naked eye from the earth. . The next return of Halley's Comet will not be until 2061.

In addition to Halley's Comet, other comets that can be seen with the naked eye include Comet Hale-Bopp , Comet Hyakutake 2 , Comet McNaught . But they have all moved away from the sun, becoming dim and invisible. Currently, there are no large comets visible to the naked eye.

And when a comet appears in the sky, we cannot see the movement of the comet. Although comets approach the sun at very high speeds, reaching tens of kilometers per second, they are still too far away from the earth to be visible to the naked eye as moving relative to the background starry sky.

The UFO was moving very fast this time. Could it be an asteroid that broke into the earth's atmosphere?

In 2021, an asteroid broke into the atmosphere and passed over Henan. At that time, many people saw a huge fireball that lit up the night sky. After burning violently, the asteroid finally exploded in the sky, and people heard a loud noise.

In this incident, people did not see an explosion in the air, nor heard a loud noise, and did not leave a long trail, which is inconsistent with the characteristics of bolide . In addition, at that time, NASA's JPL laboratory had detected an asteroid falling into Henan, but there was no relevant record of this incident.

If this UFO is not a natural phenomenon, it may be a man-made object. Some netizens speculated whether this was an rocket used for artificial rainfall, because Nanchang carried out artificial rainfall that day and launched rockets.

In response, staff from the Meteorological Bureau said that the flight of the rocket was a parabolic trajectory, which was inconsistent with the flight characteristics of the UFO. Moreover, the place where the artificial rainfall was carried out was not in the urban area, but people saw this UFO in the urban area. Therefore, rockets can be ruled out.

Although it is not a rocket, it may be a rocket. For example, this is the scene captured by witnesses when the Falcon 9 rocket was launched not long ago:

However, the carrier rocket was not launched in our country that day. In addition, there are no reports of rocket debris or scrapped spacecraft re-entering the atmosphere. Only on the night of August 31, the wreckage of the Long March 4 rocket will pass over Nanchang. The wreckage is still in space, and a bright star point can be seen flying through the sky locally. Unlike this time, UFO incident.

Seeing this UFO may make some people think of the mysterious reusable spacecraft that our country was testing before, the "aerospace plane". Could it be that it has returned to the atmosphere?

According to tracking data from the U.S. Space Force, China’s space plane is still flying in space and has not returned to Earth. From the time of launch to the present, the aerospace plane has been flying in orbit for nearly a month. A week ago, it conducted a orbit maneuver to raise the altitude of the flight orbit.

In addition, if the aerospace plane wants to return, it should land horizontally at an airport in Lop Nur like it did two years ago, and will not transit over Nanchang. Therefore, this UFO has nothing to do with the aerospace aircraft.

As for whether it is an alien spacecraft, this possibility should be unlikely. There is currently no evidence that alien civilization has visited the earth. Rather than assuming that it is an aircraft of an alien civilization, it is better to assume that it is an aircraft made by humans. It is just that the distance is too far and it is not clear what kind of aircraft it is.
