There is a faraway planet that could potentially sustain life
As far as we know, our planet is one of a kind. We have yet to discover another heavenly body that fulfills the prerequisites to sustain life as ours does. The most similar globe researchers have found is Gliese 581g, which is located about twenty-light years away.
However, it is still unconfirmed whether it exists or not. Furthermore, although it is estimated to be tidally locked to a star like the Earth is to the Sun, we have no way of knowing whether the planet has an atmosphere dense enough to circulate heat. The planet’s surface would also need to be able to sustain life for it to be habitable.
