The notable project that NASA heads opens general to strap telescopic plan to had fallen next heavy curtain, because binoculars became bad, but follow-up task still is undertaking in, the short range that just discovers begins to put delay. Search through opening general to strap dimensional binoculars with the earth each index close or the planet outside be located in appropriate to reside the solar system inside the belt, the star that this plan will control to 100 thousand has planetary approach (constant) the observation of astral phenomenon. Among them, NASA straps the pertinent information of 452b at announcing the terrestrial planet outside the department to open general in July 2015. The planet outside this department is apart from us to make an appointment with 1400 light-year, be called by close " the earth 2 " or " earthly cousin " .
According to data, the quality that opens general to strap 452b, rotation, surround each index such as Mu Xing is very as similar as the earth, be considered as strong " the 2nd earth " await anthology, opening general to strap 452b of course also is not most the planet that resembles the earth, because open general to strap 452b,had been not existed by the proof greenery, marine without liquid state water also, just the physical parameter such as orbit is close to the earth quite. Coming is not fitting room planet then, not certain still. The planet outside still having other department at the same time also has the characteristic that is close to the earth, for instance Gelize 667Cc, this is discovery of European southern observatory is dilettante star, not be to open general to strap binoculars, be apart from the earth only 22 light-year, but 28 days are only all round its orbit, because this has life unlikelily.
Gelize 581g also is await the person that choose potentially, distance earth makes an appointment with 20 light-year, quality is greater than the earth, belong to super earth cavalcade. Earthly likeness index is 0.89, or the index is earthly likeness of spark 0.7, because this planet also is potential. The place of the different common of 581g depends on Gelize on fitting house band, not close not far distance just suits liquid state water to exist.
