Because at least six variables are absolutely required to completely represent an elliptic orbit with this set of parameters, then six variables are required to represent an orbit with any set of parameters.
22.
So when Mercury fall 100km toward Sun, a perpendicular velocity make up for that 100km ( assuming circular orbit for simplicity, elliptic orbit bit more complicated, but general principle is the same ).
23.
When n = 2 theory states that these two bodies would have elliptic orbits ( well, not exactly, the orbits may also be hyperbolic or parabolic, but we assume that they are ellptic ).
24.
Were the same face of the earth to remain towards the sun at all times, we would have neither days nor seasons, other than a minor variation due to the earth's slightly elliptic orbit.
25.
Further applying special relativity theory to the elliptic orbits, Sommerfeld succeeded in deriving the correct expression for the fine structure of hydrogen spectra ( which happens to be exactly the same as in the most elaborate Dirac theory ).
26.
Also, if your jump-off point was high enough, you would find yourself in an elliptic orbit and never reach Earth at all .-- talk ) 21 : 15, 30 May 2007 ( UTC)

In these treatise, Vieta used decimal numbers ( twenty years before Stevin's paper ) and he also noted the elliptic orbit of the planets, forty years before Kepler and twenty years before Giordano Bruno's death.
28.
When they get kicked out of the Oort cloud ( e . g . due to collisons ), they can end up in a highly elliptic orbit that brings it close to the Sun for a short amount of time.
29.
:: "'Geosynchronous transfer orbit "'- A geocentric-elliptic orbit where the perigee is at the altitude of a Low Earth Orbit ( LEO ) and the apogee at the altitude of a geosynchronous orbit.
30.
If the velocity of the asteroid dips below the velocity needed to escape from the planet's sphere of influence at the asteroid's distance, its trajectory changes from a hyperbola to an elliptic orbit, and the asteroid is captured.
