New Exoplanet 55 Cancri f

Astronomers have discovered that one of the planets in binary star system 55 Cancri is potentially habitable.The study’s authors, Kaspar von Braun of the California Institute of Technology and his colleagues describe the properties of the binary star system 55 in the constellation of Cancer, called 55 Cancri f.

New Planet Near the Triple Star HD 132 563

More recently, scientists announced the discovery of new planets near the triple star HD 132 563.The main star, HD 132563A, is binary. The study conducted by a team of scientists led by Silvano Desidera of the Astronomical Observatory of Padua, Italy. The new planet moves on the orbit of the second star in the system HD 132563B. As in the binary component of the main star, the new planet was detected by spectral analysis.

Life Could Exist on Exoplanet’s Satellites

Computer modeling shows that more than 5% of the giant exsoplanets may have habitable moon, if these planets orbit at a distance from their stars.This computer modeling developed by Simon Porter and his colleagues at Lowell Observatory in Arizona, includes 12 000 hypothetical Earth-sized exoplanets who had been captured by gas giants and became their satellites.

Exoplanet MOA 2009 BLG

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.
