> need the gravity

There have been experiments with pregnant rats that were launched into space and successfully delivered litters afterwards.

Rats born in space struggle to orient themselves right side up in gravity, but they figure it out in a few days.

From what I can find, there haven’t been any experiments on conception or zygote implantation in space, but that’s because they can’t get the rats to figure out how to bang in zero gravity, not because of any specific reason it shouldn’t work.

This is a little reminiscent of the NASA scientists who were convinced that microgravity would interfere with Sally Ride’s menstrual cycle.

We don't. Not for this "small" of an astronomical size. The op you replied to is laughably off-base. At it's most "extreme" definition, the solar system could be said to be 12-24 trillion miles. This is if you consider the entirety of the theorized "Oort cloud" as part of the solar system - which the article does not specify.

If your definition of the "solar system" is maybe double the circumference of Pluto's orbit then we are talking only 20 billion miles. A literal quintillion miles is about 40% the size of the Milky Way GALAXY. That's like 140k light years
