Kepler 186f

A cousin to Earth?!?

 

A New planet has been found! Its name is Kepler-186f. Kepler-186f has about the same amount of space between it and Kepler-186, (the star of the system) as the sun and earth.  It could have enough space between it and Kepler-186 to be able to sustain life! We recently have been looking at that part of space for similar planets to earth,  and they found one!

NASA is going to attempt to build a satellite that will be able to make it all the way to Kepler-186f. The chances of that happening are very low being that Kepler-186f is 500 light years away and the furthest satellite we have is only .00005 light years away. But recently NASA has made a satellite able to leave the galaxy! It has been sent out of the galaxy to find life! But it could take years to reach another planet.

Kepler 186f was found on April 17, 2014. The light form Kepler-186 (the star of the system) is the same amount of light that Gliese 581d. Giese 581d was the fourth exoplanet to be discovered orbiting a red dwarf (like our sun).  It’s  far away from where Kepler 186 is located.  Kepler 186f is supposed to be about 26% larger than earth.

There’s a special telescope prepping to leave the atmosphere sometime in 2018 called James Webb Space Telescope (JWPT). Though it won’t be launched until 2018, NASA is in a rush trying to make sure to do what they need to do. Luckily another NASA project called Transiting Exoplanet Survey Satellite, also known as TESS, will be launched in 2017.  Both of these telescopes will end up costing NASA about 17.6 Million Dollars! Thats nothing though compared to what we might discover with these explorations!

 

Update by Aharilyn

Kepler 186f is an exoplanet found by the Kepler telescope on April 17, 2004.  An exoplanet is a planet outside of the solar system.  Kepler 186f is special because it is the first exoplanet the size of earth found in the ‘habitable’ zone – meaning that the planet is within the range of a star where liquid water might form.  There have been other planets discovered within the ‘habitable’ zone, but they have all been much larger than earth.  Thanks to Spaceman for telling us more about it!
