Assertion: sun's orbit | /r/HasProperty | sun-synchronous
Facets:
Source sentences:
text: An orbit will be Sun-synchronous when the precession rate ρ equals the mean motion of the Earth about the Sun, which is 360° per sidereal year (1.99096871×10−7 rad/s), so we must set ΔΩ/T = ρ, where T is the orbital period.
text: Note that according to this approximation cos i equals −1 when the semi-major axis equals 12352 km, which means that only smaller orbits can be Sun-synchronous.
