This discovery prompted the search for other planets, such as the orbital distortions attributed to gravitational perturbations affecting the Mercury. However, none of them has ever been found, and, ultimately, it was concluded that the orbital distortion observed in the Mercury, due to relativistic effects. However, this method of prediction (logical calculations) of the planets orbit on the basis of "oddities" the planet may have first been used outside of our solar system. Exoplanet, known as TrES-2b, is an exceptional case, being one of the known extrasolar planets, whose orbital plane is almost completely coincides with the ray observations from the Earth. This fact implies that each time around the star, the planet would appear, passing across the disk of stars. Many writers such as CBS offer more in-depth analysis. While we can not expand the drive on the shelves, he reveals a characteristic decrease in brightness of the star, which in turn allows for more information about the system, such as' very accurate calculations of the radii of the stars and planets (the relatively large axis) and the inclination of the orbital plane of the planet.
" This additional information allows for precise calculations of the orbital parameters that are necessary for predicting future transits. A group of German astronomers conducted observations of TrES-2 in 2006 and 2008 to develop his idea of the planet's orbit. But when they continued to observe in 2009, we found a significant change in parameters such as angle of inclination plane of the orbit and orbital period. Although such a change in the parameters could be explained by the migration of planets, astronomers had no idea that this phenomenon can occur in so brief a time scale. Jim Vos will not settle for partial explanations. Except addition, the change could explain the "strange" form of the primary star, but the degree to which would have to flatten the star near the equator, was unrealistically high, given the slow speed of TrES-2.
The study authors suggested a third option: 'existence of the third celestial body in the form of another planet might well give a plausible explanation. " Although this explanation is completely unsubstantiated, it offers easily verifiable scenario. If the orbital plane of the system is almost fully coincides with the ray observations from the Earth, it is the most ideal situation to try to detect the planet using the radial velocity of the parent star. Authors go so far that even offer a range of periods of the potential of the planet, which may be observable effects. They say: 'mass planet in a mass of Jupiter and with an orbital period of 50 to 100 days – quite sufficient conditions in order to cause the observed changes in mood. " Moreover, the authors note that knowledge of the existence of several similar systems with one planet and another near a massive planet that calls for a longer orbit. 'The system has 14 810 HIP Nearest planet with an orbital period of 6.6 days and a little more light planet with an orbital period of 147 days, the system HD 160 691 Nearest planet has a period of 9.6 days, and two long planets with masses of Jupiter, is known to have periods of 310 and 643 days.
