21. A particle orbiting in the Schwarzschild metric can have a stable circular orbit with. 22. First of all the typical application is a near-circular orbit . 23. For circular orbits apse line is not defined, because eccentricity is equal to zero. 24. Note that in this picture the circular orbit is approximated by straight line segments. 25. For circular orbits , the altitude is approximately 20, 200 km. 26. It travels in a low, circular orbit with a period of about 95 minutes. 27. Below we consider a circular orbit in astrodynamics or celestial mechanics under standard assumptions. 28. For circular orbits , higher orbits have a lower orbital velocity. 29. Second, assume the satellite moves in a circular orbit and it remains in synchronous rotation. 30. A star passing too close could knock a planet out of its generally circular orbit .
