Electrons and do

Low earth orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to the ground, do not require as high signal strength ( Recall that signal strength falls off as the square of the distance from the source, so the effect is dramatic ).
The structure was completed when Johannes Kepler wrote the book Astronomia nova ( A new astronomy ) in 1609, setting out the evidence that planets move in elliptical orbits with the sun at one focus, and that planets do not move with constant speed along this orbit.
The inclination of orbits of natural or artificial satellites is measured relative to the equatorial plane of the body they orbit if they do so close enough.
Even spacecraft directly orbiting the Sun do so in planes close to the ecliptic because a direct launch into a high-inclination solar orbit would require a prohibitively large launch vehicle.

Because of the Earth's annual revolution around the Sun in an orbit that is elliptical and tilted relative to the plane of the equator, an observer at a fixed point on the Earth sees the Sun appear to move in an analemma around a mean position, taking a year to do so.
Low Earth orbit satellites take advantage of the fact that certain polar orbits set near the terminator do not suffer from eclipse, therefore their solar cells are continuously lit by sunlight.
They do, though, still have the temporal orbit ( which resembles an opening ) and the temporal muscles.
Due to the inherent long-term instability of orbits in this region, even centaurs such as and, which do not currently cross the orbit of any planet, are in gradually changing orbits that will be perturbed until they start to cross the orbit of one or more of the giant planets.

The orbit is a subset of the phase space and the set of all orbits is a partition of the phase space, that is different orbits do not intersect in the phase space.
Lower stages, like the solid rocket boosters of the Space Shuttle, or the Saturn IB stage of the Apollo program era, do not reach orbital velocities and do not add to the mass load in orbit.
Moreover, the only way the stars could be so distant and still appear the sizes they do in the sky would be if even average stars were gigantic — at least as big as the orbit of the Earth, and of course vastly larger than the sun.
