The cross-shaped asteroid looks like a spaceship

Observations with the spacecraft ESA Express demonstrate new riddle of the mysterious asteroid Oljato (Olyato). Asteroid 2201 Oljato caused a stir because of its unusual shot where he looks like a cross, flying through space and leaving a long trail.

Many Internet users are seen in this picture alien spacecraft, and thanks to this fantastic new observations hypothesis, for sure, will find more and more supporters.

In addition, Oljato has very elongated orbit, so that it crosses the orbit of three terrestrial planets: Venus, Mars and Earth. While even the astronomers find it difficult to say with certainty whether the very bright 1.8-km Oljato unusual comet or asteroid.

Back in the 1980s, the asteroid flyby in 2201 Oljato inside the orbit of Venus has caused a flurry of magnetic activity. Now the results of the observation probe ESA Express show that the asteroid has lost its magnetic activity. Scientists believe that the solution to this unusual behavior lies in the processes Oljato collision with orbital debris.

 

Oljato orbits the Sun once every 3.2 years. During its operation the probe NASA Pioneer Venus Orbiter observed three times Oljato passage between Venus and the Sun. Every once in a noticeable increase in the region was unusual magnetic peaks, known by the acronym IFES. However, more recent observations indicate that the IFES near Venus during the passage Oljato are lower than in other parts of the asteroid's trajectory.

Scientists believe that the answer to this puzzle is the process of collisions between Oljato and orbital debris. As is well known, as a result of collisions in space are formed electrically charged dust particles, which are accelerated by the solar wind. Once Oljato threw boulders into its orbit — basically a few tens of meters in diameter. They formed a trail of debris behind and in front of the asteroid. This trail was made as a kind of shield that cleared the way asteroid. As a result of the collision, "shield" with orbital debris formed a large amount of dust, which is then carried off the solar wind. At this point, Pioneer and registered peaks IFES.

Thanks to "shield" that grind debris and turned it into dust, once a very "dirty" region of motion Oljato near Venus was unusually clean. Of course, scientists are confident that the work "broom" Oljato, removing more than 3 tons of dust every day, based on the processes associated with the solar wind and the gravitational perturbations, and not to the activities of aliens.
