This paper used the similarities between the ionospheres on Mars and Earth, the most similar of the terrestrial planets, to examine the relative importance of photochemical and transport processes at dawn and dusk. The amount of plasma present in the ion
Ionospheres are the charged regions that exist within the upper atmospheres of planets, moons, and minor bodies of the Solar and other Stellar Systems. Each Solar System body that has sufficient neutral atmosphere, especially within the inner part of the Solar System, has an ionosphere that is ...
The analytical theory, based on series expansions in eccentricity and inclination, is particularly suitable for low inclination and low eccentricity orbits, while the semi-numerical one is devoted to orbits with either large eccentricities or large inclinations. The orbits of the minor planets 3710, ...
They are the shape of the Earth’s orbit (eccentricity, a 100,000-year cycle), the angle of tilt of the Earth’s axis relative to the Earth’s orbital plane (obliquity, from 21.1–24.5° in a 41,000-year cycle), and the direction in which the Earth’s axis of rotation is ...
