Does other solar system have life?
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.
Is our solar system the only one with life?
Among Trillions of Planets, Are We ‘Home Alone?’ 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.
What planets have life in our solar system?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
What planets are suitable for human life?

| Kepler-452b | Kepler-452 | 384.8 |

How can we find life on other planets?
The first thing we’ve noticed is that wherever we see liquid water on Earth, we find life. Humans, along with a vast array of other life forms, need water to survive. We can start looking for life on other planets by finding liquid water. In the solar system, it turns out there aren’t many places where this is true.
Will there ever be life on another planet?
It is unlikely, however, that familiar life forms will be found on any planet within our solar system. Life as we know it—everything from single-celled organisms to human beings—consists largely of liquid water.
Is there life outside the Solar System?
The discovery of thousands of planets orbiting nearby stars has nevertheless greatly increased speculation that there may be some kind of life on a planet outside our solar system. In the past 20 years, we have confirmed the discovery of almost 2,000 planets, called exoplanets, beyond our solar system.
Are We the only life-bearing planets in the universe?
In a galaxy that likely holds trillions of planets, ours is so far the only known life-bearing world. Are we really alone? Life in the Universe: What are the Odds? Life in the Universe: What are the Odds?
