- Of the thousands of exoplanets – planets around other stars – confirmed by our increasingly powerful telescopes, and despite extensive probing of the solar system, ours is still the only planet known to host life.

The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive.
- Kepler 186F
- Kepler 283C
- 3 & 4) Gliese 667C F and 667C E
- 5 & 6) Kepler 62E and Kepler 62F
- Gliese 581D
One of the most likely candidates for life as we know it is Kepler 186f. In fact, this is a planet that (if we could get there) we might be able to colonize with relative ease. Sadly, the world is 490 light-years away, so it would take us hundreds of thousands of years to reach (even using very liberal and generous estimates). The planet was discov...
Kepler 283c was discovered along with a host of other worlds as part of an enormous data dump from the Kepler Space Telescope. This data contained a staggering 700 newly confirmed exoplanets (keep in mind, just 20 years ago, we didn't know of anyplanets in other solar systems, so 700 in one go is quite staggering). However, this world is on the bor...
Personally, if we were going to try and make our way to any planet that might be habitable, I think I would make an argument for either Gliese 667C f or Gliese 667C e. That's because these woulds would offer an amazing view. Whe? They have three suns. Because this is a triple star system, these are two of the strangest potentially habitable worlds ...
As their names suggest, these Kepler-62 planets are some other worlds that were discovered by NASA's Kepler Space Telescope. These planets would give us a little more room to work with, as 62e is about 1.6 times more massive than Earth and 62f is just about 1.4 times as massive. These worlds are quite out there (at least as far as our ability to tr...
Gliese 581d is another one of our galactic neighbors (in the grand scheme of things, it is basically just around the corner). This world is just 20 light-years away (the closest planet covered on this list). However, despite its close proximity and its location in its star's habitable zone (alas) the planet might have a thick carbon dioxide atmosph...

Jul 31, 2024 · Beyond Earth's blue skies stretches a universe full of possibilities, including countless stars with planets that might support life. While Earth is the only known host of life, astronomers have identified several exoplanets that could potentially support it.
Nov 10, 2020 · Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability.
Oct 4, 2023 · We’re still in the early phases of cataloging with exoplanets, but it’s clear that countless worlds are out there that could host life. We know that relatively sizeable galaxies like the Milky ...
