Kepler 452b is the smallest planet yet discovered that
orbits in the habitable zone which means it has the capability of containing
liquid water on its surface. It mustn’t go unnoticed that the current
inhabitants of our beloved yet neglected planet Earth is rapidly being stripped
of its recourses which are vital and cataclysmic to human life. For in the book
The Upcycle by McDonough, Braungart,
and Clinton, explain how in today’s society, we don’t focus on changing our designs
but rather we put emphasis on being “less bad” which only perpetuates the
initial issue- improper, harmful, and wasteful systematic or structural
designs. With that being said, we are running our potential for life into the
ground and need to expand to other habitable plants.
But have no fear, we can start over on Kepler 452b! Kepler
452b is not only in the habitable zone, but it is also 60% larger in diameter
than Earth, meaning it has a larger capacity for human life. In addition, it has spent 6 billion years in the habitable zone which is significantly longer than Earth,
giving the planet ample opportunity to create life. And, as we know, a main
contributor to the fact that our planet’s sustainability is plummeting is due
to overpopulation. With human expansion to Kepler 452b, it would allow for more
room as well as recourses to efficiently support more lives. Also helping
support life on Kepler452b is its potential rocky surface, again closely
resembling that of Earth.
With that being said, the planet’s orbit is only 5% longer
that that of Earth, so time adjustment wouldn’t be much of an issue. Speaking of time, the Kepler 452 system is
1,400 light years away in the constellation Cygnus.
As we know, when stars begin to die, they grow larger and
hotter. Kepler 452b’s sun, Kepler 452, is 1.5 billion years older than our sun
and, while it is 10% larger and 20% more luminous it remains the same
temperature as our sun. This could mean it has potentially the same or even
longer life expectancy!
Though the planet closely resembles Earth, there would still
be some large differences in relation to living on this planet. Due to its
significantly bigger size, the gravitational force would most likely be
stronger than it is on Earth, a strange adjustment for humans as it could potentially create a difference in body structure.
To better reinstate the point that Kepler 452b is our best
candidate for a new life-sustaining planet, NASA ‘s Ames Research Center’s lead says they refer to Kepler
452b as an older, bigger cousin to Earth. They are clearly giving great hope
and optimism to the future of the newly discovered planet. If humans were able
to expand life to Kepler 452b, we would have a second chance at living
efficiently and sustainably on a new planet.
