So today we will introduce you top 10 fact about Google that you may not know.
An international team of astronomers has described a new exoplanet MOA-2009-BLG-266Lb, which is only 10 times larger than Earth by mass. Scientists have acted according to the method of gravitational microlensing, which can detect low-mass planets in wide orbits.As it turned out, the mass of the star is 0,56 ± 0,09 sunny. Planet moves around its orbit with semi-major axis of 3.2 (+1.9, -0.5) а.e.,making one revolution in 7.6 (+7.7, -1.4) years.MOA-2009-BLG-266Lb was one of the first low-mass exoplanet located in “snow line”, conventional boundary, which takes place at such a distance from the luminary, where the temperature allows the existence of hydrogen compounds (water, ammonia, methane) in the form of solid ice particles.
In our solar system, this line, which is 2.7 a. e. from the star, separates the terrestrial planets from the gaseous giants. As the “parent” star MOA-2009-BLG-266Lb is approximately two times lower than the Sun, by weight, “snow line” passes at twice smaller distance from it (~ 1.5 a.e.).
