Unknown satellites in the solar system. Are they extraterrestrial? Videos.
In our solar system there are many objects such as asteroids, comets or planets that astronomers have documented and described in detail. Of course, there are also satellites and satellites made by humans or larger space debris, such as burned rocket launchers.
In space, however, there are objects that astronomers can not identify, and some even consider them non-Earth satellites. What are they actually?
1. We do not know the celestial body
Astronomers in space are constantly searching for unknown asteroids that could also endanger our planet Earth. That is why, in 1999, in the American state of New Mexico, the Linear Satellite project was created, where scientists searched by means of an automatic telescope to search for unknown or unidentified asteroids.
Over the course of this project, they discovered an unknown body with a diameter of 30 to 50 meters, which runs around the Sun on a nearly circular path with a circulation period of 1.09 years. This object, which was named 1999 CG9, is about 158 million kilometers from the Sun, about 9 million kilometers away from our planet Earth. The greatest mystery for astronomers is its atypical orbit, which is almost circular. All other celestial bodies move along the elliptical path.
Brain Marsden of the Harward Smithsonian Center is convinced that due to the size of the object, it can not be the burning degree of a carrier rocket. Therefore, he believes that this object could come from a moon that has a small gravitational force when it was thrown into space in the event of a larger meteorite.
However, a detailed analysis of the composition of the 1999 CG9 satellite would be required to confirm this assumption. Some scientists, however, are skeptical about this, because it would be a really good piece of the Moon that was thrown into the universe, and its circular path, which scientists have not explained yet.
2. Unknown Celestial Body
Even in November 1991, however, astronomers from the Kitt Peak Observatory in the US discovered a body that behaved similarly to the 1999 CG9 object. The Sky & Telescope magazine, which has been named the 1991 VG even referred to as a “true UFO,” because its orbit almost exactly copies the orbit of our blue planet, and it also features light effects.
The biggest mystery for astronomers is the fact that the 1991 VG does not reflect the radar waves at all, which is quite a matter of fact for other cosmic bodies. Therefore, the overwhelming majority of scientists consider the possibility that the natural body would behave as absolutely excluded.
Some scientists think it could be the remains of an earlier probe or rocket, but later it was found that such a orbit does not correspond to the calculated orbit of missiles and satellites so far. At the beginning of December 1991, this body traveled only 450,000 kilometers from the Earth
There is the possibility that this mysterious object is in fact some non-Earth probe or satellite, as was said by Australian astronomer Duncan Steel of the University of Adelaide. Later, however, he took his words back and said he was not convinced that this body was of extraterrestrial origin.
In the summer of 2017, the 1991 VG spacecraft can be seen from the southern hemisphere, and astronomers believe they can identify the satellite that is copying the Earth’s orbit. It will be just one of the burnt levels of the carrier rocket than most scientists think, or it may be a non-Earth probe, which does not exclude British astronomer Duncan Forgan. Let’s surprise you.
