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
