Kepler 452b: Second Earth Perhaps Not For Us

Many scientists and space enthusiasts awaiting news about a second Earth were answered when NASA announced the results its phoenix-like telescope, Kepler, had found. The exoplanet that created so much excitement has a size and age reminiscent of Earth’s, and, critically, even exists in the Goldilocks zone of its Sun-like star, ensuring its neither freezing nor burning away any possibility of complex life.

Size, age, and other specs of second earth

Known as Kepler 452b, it’s the smallest exoplanet we’ve discovered existing within that coveted circular area of a G2 star colloquially called the Goldilocks zone. G2 is a category of star-luminescence that our own Sun also falls under. The new planet is about 6 billion years old, has a diameter sixty percent that of the Earth, and is located in the constellation Cygnus, roughly 1,400 light-years away from us.

WHY Kepler 452b IS SIMILAR TO EARTH

Kepler 452b orbits its sun-like star in a year lasting 385 days, which puts it undoubtedly within the habitable zone, which means it is very likely it will have liquid water.

But we shouldn’t get too excited to leap into our planet’s family’s arms.

DON’T JUMP THE SHARK, BECAUSE YOU CAN’T

The associate administrator of NASA’s Science Mission Directorate at the agency’s Washington headquarters, John Grunsfeld, called Kepler 452b a “close cousin to the Earth.” This is an apt description. Since the planet is rocky, like ours, yet smaller, the difference in gravity could do more harm than good.

Additionally, initial studies have suggested to us that the planet has entered a rather misfortunate runaway greenhouse gas phase, similar to what happened to Venus long ago, which is why the planet is so hot and antagonistic to life.

COLLECTIVE FERVER & SENTIMENTALITY

But this unfortunate atmospheric development didn’t stop the Chinese from getting excited, whom after hearing about the new planet flooded social media with over 44 million posts about the planet’s “substantial opportunity” to host life. China’s microblogging service, Sina Weibo, the hashtag #AnotherEarth exploded, with nearly 90,000 participants in the discussion.

Their state-run Xinhua news agency, Xinhua, had to quell high hopes for Kepler 452b’s biocompatibility, but the Chinese populace remained undaunted in its manic ravishing of the discovery, with the highest trending comment “Even Earth has found its other half, why am I still single?” lending credence to the notion of humankind’s innate alienation.
