The eccentricity of Mercury's orbit makes this resonance stable—at perihelion, when the solar tide is strongest, the Sun is nearly stationary in Mercury's sky. [ 130 ] The 3:2 resonant tidal locking is stabilized by the variance of the tidal force along Mercury's eccentric orbit, acting on a permanent dipole component of Mercury's mass ...
Mercury orbit (Hermeocentric orbit, named after Hermes): An orbit around the planet Mercury. Venus orbit (Cytherocentric orbit, named after Cytherea, or Aphrodiocentric, after Aphrodite): An orbit around the planet Venus. Jupiter orbit (Zenocentric orbit, named after Zeus, [3] or Latin equivalent Jovicentric): An orbit around the planet Jupiter.
Mercury, the closest planet to the Sun at 0.4 astronomical units (AU), takes 88 days for an orbit, but the smallest known orbits of exoplanets have orbital periods of only a few hours, see Ultra-short period planet. The Kepler-11 system has five of its planets in smaller orbits than Mercury's.
The following outline is provided as an overview of and topical guide to Mercury: Mercury – smallest and innermost planet in the Solar System. Its orbital period (about 88 Earth days) is less than any other planet in the Solar System. Seen from Earth, it appears to move around its orbit in about 116 days.
The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58] Asteroid spectral types are mostly Tholen, but some might be SMASS.
The longitude of the ascending node, Ω, the inclination, i, and the argument of periapsis, ω, or the longitude of periapsis, ϖ, specify the orientation of the orbit in its plane. Either the longitude at epoch, L 0, the mean anomaly at epoch, M 0, or the time of perihelion passage, T 0, are used to specify a known point in the orbit. The ...
It's a universal size that fit just about any size tablet, phone or e-book. Plus, it includes a pocket on the side that can store small items you don't want to lose like your page turner.
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
