Linear Flow On The Torus
... For a linear flow on the torus either all orbits are periodic or all orbits are dense on a subset of the n-torus which is a k-torus ... When the components of ω are rationally independent all the orbits are dense on the whole space ... rotation on a circle and therefore its orbits are dense on the circle, as a consequence the orbits of the flow must be dense on the torus ...
Detached Object - Orbits
... They often have highly elliptical, very large orbits with semi-major axes of up to a few hundred astronomical units (AU, the radius of Earth's orbit) ... Such orbits cannot have been created by gravitational scattering by the gas giants (in particular, Neptune) ...

The second and third orbital circumnavigations, the first two to have multiple orbits, were made by Gherman Titov (17.5 orbits, a little over a day, for the Soviet ...

Stability Of The Solar System - Overview and Challenges - Predictability
... The planets' orbits are chaotic over longer timescales, such that the whole Solar System possesses a Lyapunov time in the range of 2–230 million years ... In all cases this means that the position of a planet along its orbit ultimately becomes impossible to predict with any certainty (so, for example, the timing of winter and ...

Famous quotes containing the word orbits:

    To me, however, the question of the times resolved itself into a practical question of the conduct of life. How shall I live? We are incompetent to solve the times. Our geometry cannot span the huge orbits of the prevailing ideas, behold their return, and reconcile their opposition. We can only obey our own polarity.
    Ralph Waldo Emerson (1803–1882)
