# What is this elliptical orbit?

Most natural elliptical orbits are one sided as shown below from wiki.

What is an elliptical orbit where perigee and apogee are closer to being equal in distance than not? The object would have to skip off the atmosphere to maintain this orbit.

I have learned that this orbit would not be possible without spending energy and is not a stable orbit. Which makes this question off-topic no matter how I word it. I have flagged it for being off-topic.

• That orbit does not appear to be physically possible (without some external force acting on the orbiting bodies). In a 2-body system the centre of mass has to be at one focus of the ellipse. Perhaps you need to explain the diagram some more? Oct 28 '18 at 21:20
• What is an elliptical orbit with 2 equal sides called? All ellipses have equal sides relative to the center. Relative to the foci, the sides are equal if you compare both sides along the semi major axis. You seem to want equal sides along the semi minor axis relative to the foci. That's a circle. A circle is a specific type of ellipse. It's no longer an ellipse if you create some kind of theoretical pumping motion or energy exchange. Your orbit would need to be created artificially and it would no longer be an ellipse. I'd call it an artificial, perturbed or manipulated orbit. Oct 28 '18 at 22:51
• I'm voting to close this question as off-topic because you're asking the name of a path you describe as an orbit, but no such orbit is possible, so it has no name. Oct 29 '18 at 3:04
• @StephenG I am voting this question to "leave open", because your comment is not a close reason, but the correct answer. Oct 29 '18 at 5:10
• The answer to this (completely changed) question is - a circle. Nov 3 '18 at 11:16
