Another thing that may affect the probability of life in a solar system is the number of planets. More planets seem to make the planetary orbits much more circular and stable, allowing more time for life to occur and develop.
This matters because, as far as we can see, our solar system has more planets than any other system we have been able to observe (so far.)

- ben_w 6y ago> as far as we can see, our solar system has more planets than any other system we have been able to observe I may be out of date, but I thought that was an artefact of our methods and equipment rather than anything else — we can only see big things close to their stars, so if we were looking at our own system we’d miss (I forget, so e.g.) Mars, Uranus and Neptune?
