Who knows - the options are almost limitless. Depends on what you term "life " as
Candidates are:-
Though there is evidence of other star systems (about 50), there is no evidence that any of these have planets that are able to sustain life. Additionally, no technology exists that enables travel to another solar system if a suitable one is found.
The sun, followed by the gas giant planets.
We have no way of predicting accurately where intelligent life can exist, we can only predict where human or earth-based life can exist. Life is a self-repeating chemical system, and it can potentially exist in any solar system, even on frozen moons that still have warm cores. Life that would be truly "alien" to us might even exist in the cold, seemingly dead space between stars, we can't know.
From approximately 1.5 to 2.0 solar masses snow FAR
The rotation of the earth about its axis gives us night and day. Night and day is good. All day or all night isn't so good, usually.
Large Moons of the Jovian planets. Enjoy.
if there were no solar system then there would be no life?
It's the only solar system we can confirm has life on a planet.
The best bets for life in our solar system are Mars, Jupiter's moon Europa, and most recently discovered to be an even better bet, Saturn's moon Enceladus.
Solar-mass stars because they have both a large habitable zone and a long stellar lifetime.
My best guess would be fifty-fifty. While we simply don't know for certain - there could be life.
There is no known life anywhere in our solar system except on Earth.As currently defined our solar system only has 8 planets.
Probably. A few satellites of the gas giants may have liquid water (and thus MIGHT be candidates) and Titan with its methane atmosphere is interesting ... but so far we have not a shred of evidence for life elsewhere.
My best guess would be fifty-fifty. While we simply don't know for certain - there could be life.
No alien life has been found so far; either inside or outside our Solar System.
it has life on it
