Besides solar energy, the primary characteristic of the Solar System enabling the presence of life is the heliosphere and planetary magnetic fields (for those planets that have them). These magnetic fields partially shield the Solar System from high-energy interstellar particles called cosmic rays.
Aside from Earth, no planets in the solar system are known to harbor life. Mars, Europa, and Titan are considered to have once had or currently have conditions permitting the existence of life. Multiple rovers have been sent to Mars, while Europa Clipper is planned to reach Europa in 2030, and the Dragonfly space probe is planned to launch in 2027.
Our solar system is in one of the Milky Way galaxy’s spiral arms called the Orion Spur. 5. A Long Way Around Our solar system takes about 230 million years to orbit the galactic center. 6. Spiraling Through Space The Milky Way is a barred spiral galaxy. 7. Room to Breathe Our solar system has many worlds with many types of atmospheres. 8.
Humanity's knowledge of the Solar System has grown incrementally over the centuries. Up to the Late Middle Ages – Renaissance, astronomers from Europe to India believed Earth to be stationary at the center of the universe and categorically different from the divine or ethereal objects that moved through the sky.
The heart of the Solar System is the Sun, a yellow star of moderate mass somewhere in the middle of its life cycle. That star is what drives most of the physical processes in the system, from heating Earth’s atmosphere to allow life, to gently pushing asteroids around and giving comets their tails.
So far, we've only know about life on Earth, but NASA is searching for life on other worlds in our solar system and beyond. Our solar system extends much farther than the planets that orbit the Sun. The solar system also includes the Kuiper Belt that lies past Neptune's orbit.
The Six Moons Most Likely to Host Life in Our Solar System
The largest moon in our solar system might contain several layers of rock, water and exotic high-pressure ices. Interactions between rock and water are fundamental to microbial diversity on Earth.

List of potentially habitable exoplanets
This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky.
