These ships would operate in three low, (1,000-mile altitude, 2-hour period) circular, co-planar, and polar orbits. The particular orbit chosen was the result of compromise among the many mission requirements of the force. Since this force would furnish the space fleet the greatest portion ...
(Note: in the orbital diagrams below the sizes of the Sun and planets are NOT to scale) Synodic and Sidereal Periods of Revolution As the planets move around the Sun they change their positions relative to each other. Since the inner planets, in smaller orbits, move faster around the Sun ...
"When planetary orbits were finally deciphered in recent history, it became clear that Venus and Mercury had smaller orbits inside the Earth's orbit, which caused their retrograde loops." Star Trek He further added that their results demonstrated that the necessary conditions exist to modify planet...
Planetary orbits (or orbits of artificial satellites) can be simply described using a basis for R3 chosen so that the orbit lies in a coordinate plane. It is also desirable to express the planet's position in terms of a different basis chosen to simplify the earth's position with respect ...
Their composition is still uncertain but the low albedo (0.05) suggests that in contrast to Saturn's rings, they are not dominated by water ice but rather by dust particles. Moreover, their orbits are characterized by eccentricity and inclination. They have very sharp boundaries, caused by the...
He was not making the relatively pedestrian claim of the folk taxonomy, that the Earth orbits a luminous body directly while the Moon orbits a luminous body only secondarily, and thus the Earth and Moon are different in that particular way. He saw instead the truly important thing: that the...
There are four possible final states of chaotic particles: collision with the planet, collision with the star, escape, or bounded but non-collision orbits. In our investigations, within the framework of the planar circular restricted three body problem for planet-star mass ratio mu in the range...

In order to damp the high eccentricity of the planets orbits typically observed in the stage 3 models, different from the near circular orbits of Earth and Venus, a remnant of the gas nebula still present during the final stage (Agnor &Ward 2002; Kominami &Ida 2002) seem to be required...
Asteroids that stray faroutsidethe main belt are of interest mostly to astronomers. But asteroids that comeinward, especially those with orbits that come close to or cross the orbit of Earth, are of interest to political leaders, military planners—indeed, everyone alive on Earth. Some of these...
