Ceres is about 2.5AU from the sun, has more water than Earth and the mass of 0.00015 Earths. The ort cloud is 1,000-100,000 AU away. I am making the assumption

I am making the assumption that we will have a much stronger preference for water closer to Earth, and we aren't talking about large gravity wells.
- DuskStar 7y agoThere's a massive practical difference between Ceres size gravity wells that can be escaped with a half-decent cannon and ones that can't. And I've never heard of people suggesting there might be life on/in Ceres.
