| Nov 17, 2021 at 17:26 | comment | added | Anders Sandberg | @PeterMortensen - See physics.stackexchange.com/questions/458444/… for the circularisation issue. Basically, this is a pretty slow process for non-heavy bodies. | |
| Nov 17, 2021 at 10:58 | comment | added | nick012000 | "Such orbits may not be very elliptic-looking since there can be multiple turns per perimelasma approach (OK, periapse is the more common term)" So, it'd look like a spirograph drawing, then? | |
| Nov 16, 2021 at 23:47 | comment | added | Peter Mortensen | But this ignores radiating away energy through gravitational waves(?). And circularise the orbit(?). | |
