That's a good question. If you make them just slightly different in mass then you can select "Orbit All" (or right click on the smaller one and select "Orbit Parent").

(Although after you make the masses different you need to let the system increment at least one frame or the Orbit buttons won't work correctly. This minor issue will be fixed in the next update)

You can now change the mass back to the same as the other if you wish. Then click on the button "Balance Sys. Momentum.


Eventually I'll add a feature that will let you select both bodies and then click Orbit to achieve the same effect.

Let me know if you have any more questions.
