Stability of planets in the nearest star system (Alpha Centauri) manifests the origin of extraterrestrial UFOs
Alpha Centauri is the closest star to us that manifests existence of extraterrestrial life in its planets. It is a triple star system with two if the stars forming a close binary and a third orbiting this pair at a much greater distance. Scientists have very recently learnt that the star system has stable planetary orbits.
Alpha Centauri A is the principal member or primary of the binary system, being both slightly larger and more luminous than our Sun. Like the Sun, it is a main sequence star with a similar yellowish-white color. Alpha Centauri A is about 10% more massive than our Sun, with a radius about 23% larger. Alpha Centauri B is the companion star or secondary to the primary star, appearing slightly smaller and less luminous than the Sun. By mass, α Cen B is about 90% of the Sun, and is 14% smaller in radius. A likely solar-like rotation period of some 36.8 days has been determined. The star B emits a higher level of energy in the X-ray part of the spectrum.
According to recent computer simulation Alpha Centari Triple Start System has many expo planets similar to the earth which cannot be sensed with terrestrial technologies. These planets have stable orbits, have water and an atmosphere that can provide an ozone layer to block the tltraviolet radiation.
Any suspected Earth-like planet around Alpha Centauri A would have to be placed about 1.25 AU away - about halfway between the distances of Earth's orbit and Mars'' orbit in our own Solar System, so as to have similar planetary temperatures and conditions for liquid water to exist. For the slightly less luminous and cooler Alpha Centauri B, this distance would be closer to its star at about 0.7 AU, being about the distance that Venus is from the Sun.
NASA all on a sudden has taken its foucus on Alpha Centauri Star System. The word in the grapevine is that NASA sees something that we can only predict. Both Proxima Centauri and α Centauri AB are among the listed "Tier 1" target stars for NASA's Space Interferometry Mission (SIM). SIM is designed to be able to detect planets as small as three Earth-masses or smaller within two Astronomical Units of a "Tier 1" target.
