If , someone will ask a question . Is there any place where we can see two sun ? Then don’t hesitate to say “Yes”.In our universe there are many solar system which have twin stars and planets which orbiting these star and called circumbinary planet. These planets have unpredictable weather and temperature.
Scientist detected 20 circumbinary planets with one unconfirmed star system entry MACHO-1997-BLG-41.
NASA launched Kepler space observatory on March 7, 2009 to find earth like planet in this universe . Since 2009 , kepler observed 10 circumbinary planets having twin star. In 2011 Kepler-16b discovered which is made from half rock and half of gas and similar to our solar system planet Venus . Kepler-16b orbiting stars which is smaller than our sun. one is 69 % of our sun and other is 20 % of our sun. This planet lies outside habitable zone and water may be present on its surface because both stars are cooler than our Sun. It takes 225 day to complete its orbit. If, we exchange sun with star system Kepler-16b then our earth temperature would be less than 200 Kelvin.
After that ,In 2012 Kepler 64 ,Kepler-34,Kepler-35,Kepler-38,Kepler-47 b,Kepler-47 c found. In 2015 Kepler-413 and Kepler-453 B discovered.
Star system Kepler-47 located in Cygnus constellation which also known as Swan. This star system having two planet Kepler-47 b and Kepler-47 c. The outer planet Kepler-47 c comes in habitual zone like earth but it is formed with gas and not suitable for life like our planet Uranus .
Temperature and weather on planet lies in binary system changes at rapid rate because of two star system .They have more day light which initialize every process at rapid rate which not initialize in absence of light.
Eclipse occurs on these planets at every week or month depends on their orbit completion time.
Kepler 413 b is 2,300 light-years from earth and present in Cygnus constellation with small orbit time of 66 days. This planet is too warm for life.
The latest discovery is In Lyra constellation which is 1400 light years from earth with star system Kepler-453 B . This planet is also not suitable for life but moon of this planet could be suitable for life .This planet 6.2 times of earth.
In future the count of binary star system may increase. Until these discoveries gives us wing to think outside the box and inspire us to imagine anything. In coming future we will discover amazing planet which satisfy every condition that fulfill origin of life in multiple star system. These star systems influence us and lead us to new possibilities beyond what we think we know at present.
