Astronomers from Cornell University (USA), calculate the mass of the Sun to the nearest exoplanets - Alpha Centauri B b, which is located at a distance of 4.37 light years from the solar system.

To calculate the exact weight of Alpha Centauri B b must be a precise definition of the orientation of the orbit relative to the observer on Earth. If you look at the side of the orbit, the calculations show that the exoplanet is super-Earths and has a mass about three times the size of Earth. If you watch the orbit above, Alpha Centauri B b can be considered a hot Jupiter, and the orientation of the intermediate orbit correspond to intermediate masses.

Scientists have conducted a numerical simulation of the dynamic stability of a double star system Alpha Centauri A and B, as well as extrasolar planets. In the experiment, we tested different parameters of the orbit of the exoplanet with the inclusion of goat, and the action of tidal forces of nearby stars. Thus it was possible to determine the boundaries of sustainable movement Alpha Centauri B b for the last billion years and to estimate the inclination of its orbit, which is an extrasolar planet would be faced with his star and would be ejected from the system.

The results show that the exact mass of Alpha Centauri B b is in the range of 2.7 Earth masses.
