An international team of researchers and astronomers has discovered an almost identical twin to our sun in a promising development that can help limit our search for another habitable world.

It is estimated that up to 85 percent of all stars can be binary pairs (or triplets or quadruplets) because stars tend to be formed in star schools, which are big clouds of gas and dust that can often form thousands of stars. 19659003] Using advanced technologies, including the latest astrometric data from the ESA GAIA Space Observatory, researchers at the Instituto de Astrofísica e Ciências do Espaço (IA) in Portugal believe they have found our sun’s binary siblings about 184 light years ago.

“Since there is not much information about the past of the sun, the study of these stars can help us understand where in the Galaxy and under what conditions the sun was formed,” said Astronomer Vardan Adibekyan from IA.

Like our sun, HD186302 is a G-type main sequence star. It is slightly larger than assumed siblings, with approximately the same surface temperature and brightness, and is also about 4.5 billion years old, with a similar chemical composition.

These details are crucial because our solar size, age, temperature, brightness and chemical composition offer the best, and apparently, only the conditions for maintaining life as we know it in the universe at present.

“If we are lucky and our sibling candidate has a planet, and the planet is a rocky type, in the inhabited zone and finally if this planet was “polluted” by life-seed from the earth, we have what we can dream about – a Earth 2.0 that revolves around a Sun 2.0, “ Adibekyan added.

A former challenger for lost sunbrothers was an F-type star HD162826 discovered in 2014. F-type star s is blue to white in color, burns warmer than our sun and have a larger mass an average of 1.7 times the sun. They are also much brighter.

Now, IA researchers are planning to scour the surrounding cosmic countryside around the newly discovered potential twilight for signs of planets that can look striking as our own.
