Well, there are planets outside of the solar system, and there is one that is livable, but I don't know what it is called.
The planets are part of the makup of the solar system. I guess you could say the sun provides light for the planets and gravety that holds them to the solar system.
They could, but as of now, no astronauts have travelled to any other planets in the solar system.
The Solar System is made up of the planets. It could not be smaller than the parts that make it up.
The moons of the big planets can go into eclipse when they are in the shadow of their planet.
One interesting topic in space is the search for habitable exoplanets outside our solar system. Scientists are looking for planets with conditions similar to Earth that could potentially support life. The discovery of such planets would have significant implications for our understanding of the universe and the possibility of life beyond Earth.
It is possible, even likely, that there are other planets that could support life. We have yet to find any.
Mars and Venus
As far as we know, Earth is the only planet that supports life, but there have been many studies that show that some other planets have either supported life previously or could be capable of supporting life.
NO! well notyet! hopefully scientists will find other planets in 5 seconds! just joking! i have some reasons why they cant find other planets:1. IF THEY CAN LEARN ABOUT OTHER PLANETS THEN HOW COME THEY CANT LEARN ABOUT PLUTO NOW!2. the random planets outside our solar system are like 389434898375 million miles away from earth!3. they haven't named the planets yet!4. there can be thousands of planets outside our solar system! (even planets outside of other solar systems)5. it could take hundreds of years to reach a planet outside of our solar system that far!but if they could send another space probe to travel to a planet outside of our solar system that is closest to Pluto! if anyone can find LIFE on planets outside of our solar system i would want their autograph! if they're aren't then i would make a planet right next to earth (travels on the same orbit line)(1 day earliar) (if it was possible) and plant trees and make water and grow grass and gather some construction workers to build houses for me and make my own food! (take ingredients from earth to earth number 2) and make continents all over earth number 2! if earth number one ever ended i would recommend you guys to move to earth number two oh and make TVs, computers, etc.) if all this was possible i would do it! OK that's all i can say!
No other planet in our solar system could support advanced life such as on Earth. Others could support UNintelligent life. Planets in other galaxies that may support life are: OGLE-2005-BLG-390Lb , Gliese 581 c, and Gliese 581 d.
It might not be the only planet with life. Life could exist on planets outside our solar system. There is just no way of finding life on one of these planets without actually going there. There is even a slight possibility of life on Mars.
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
