Conic Sections
They're not generally used for crewed spacecraft because astronauts HATE going around the corners.

All Keplerian orbits are conic sections. For example, this one uses the base of the cone.

Discussion

Isn't the base of a cone, just a circle? How would this have "corners"? SDSpivey (talk) 01:41, 3 January 2026 (UTC)

The cone upon which a conic section exists doesn't actually have a base, it's just arbitrarily large (possibly infinitely so) in order for the section to only ever lay along the 'curve' of the cone part.
But, here, the base is wwhere you give up on plotting how far 'down the cone' you go, of the sufficiently large ellipse (or possibly parabolic/hyperbolic curve), which is indeed round but has an sharp (i.e. acute) angle between its flat (and incidentally circular) plane-section and the 'wrapped' pseudo-euclidean plane of the conic-section it intersects with. 92.23.2.208 01:50, 3 January 2026 (UTC)

Bring a jacket and spoon for orbits that go through the ice cream.Lord Pishky (talk) 01:43, 3 January 2026 (UTC)

I'm pretty sure this is the shape of the flat bottom of a cake cone. 71.212.56.254 03:02, 3 January 2026 (UTC)

They REALLY hate the flat-bottom cone orbits and the waffle cones make for a bumpy ride.Lord Pishky (talk) 18:57, 3 January 2026 (UTC)

It appears to be a cut-off section of an ellipse, so basically a regular orbit with a sharp line. (Desmos) Tanner07 (talk) 04:29, 3 January 2026 (UTC)
