The Earth today is facing a lot of crisis like overpopulation and global warming. No one can ensure that the Earth can provide a safe and comfort planet for us to live in forever. The search for a new planet to live in may sound absurd but it is definitely essential in the far future.
According to the article, the newly discovered planet, 581c, showed signs of live. Like Earth, it orbits a comfortable distance from its sun; like Earth, it maintains a surface temperature somewhere between 32 and 104 degrees Fahrenheit. Most importantly, like Earth, it could easily harbor surface water. In the biological arithmetic we know best, warmth and water often equal life. It is also about 1.5 times larger than Earth.
However, one of the problem found is that 581c is a lot nearer to the sun as compared to the Earth. (The Earth is 92.9 million miles away from the sun while 581c is just 7 millions miles away). Traveling there also becomes a problem as we took 8 months to travel to Mars, which is about 35 millions miles away. How long will it take to travel to 581 c, which is 120 trillion miles away? Thus, this planet might not be suitable to live in after all.
Do not be surprise if you would to find your future generation living on other planets. Earth simply just cannot last forever. With scientists and astronomers working on finding a suitable planet to live in, it is definitely possible.
