Topic: Avg Orbital Speed

	Orbital speed - Wikipedia, the free encyclopedia
		The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body.
		The orbital speed at any position in the orbit can be computed from the distance to the central body at that position, and the specific orbital energy, which is independent of position: the kinetic energy is the total energy minus the potential energy.
		The transverse orbital speed is inversely proportional to the distance to the central body because of the law of conservation of angular momentum, or equivalently, Kepler's second law.

	Moon - Encyclopedia, History, Geography and Biography
		As a result, some of the Earth's rotational momentum is gradually being transferred to the Moon's orbital momentum, resulting in the Moon slowly receding from Earth at the rate of approximately 38 mm per year.
		One must be reminded here that the orbital inclination is measured with respect to the primary's equatorial plane (in this case the Earth's), and that the axis of rotation's tilt is measured with respect to the normal to the satellite's orbital plane (the Moon's).
		The plane of the lunar orbit maintains an inclination of 5.145 396° with respect to the ecliptic (the orbital plane of the Earth around the Sun), and the lunar axis of rotation maintains an inclination of 1.5424° with respect to the normal to that same plane.

	Jupiter Information - The Planets
		The inner group were all discovered during the Voyager program except for Amalthea, all have diameters of less than 200 km and orbit at radii less than 200,000 km, and have orbital inclinations of less than half a degree.
		The third group were all discovered in the 20th century but before Voyager, have diameters less than 200 km, and orbit between 11,000,000 and 12,000,000 km with an orbital inclination between 26° and 29°.
		All Jovian moons are tidally locked with Jupiter, and therefore have the same rotational period as their orbital period.

		Wind speeds of 600 km/h are not uncommon.
		The Galileo orbiter itself experienced a more rapid version of the same fate when it was deliberately steered into the planet on September 21, 2003 at a speed of over 50 km/s, in order to avoid any possibility of it crashing into and possibly contaminating Europa, one of the Jovian moons.
		A basic division is between the eight inner regular moons with nearly circular orbits near the plane of Jupiter's equator, which are believed to have formed with Jupiter, and an unknown number of small irregular moons, with elliptical and inclined orbits, which are believed to be captured asteroids or fragments of captured asteroids.

	Moon (via CobWeb/3.1 planetlab1.isi.jhu.edu) (Site not responding. Last check: 2007-09-11)
		The plane of the lunar orbit maintains an inclination of 5.145 396° with respect to the ecliptic (the orbital plane of the Earth), and the lunar axis of rotation maintains an inclination of 1.5424° with respect to the normal to that same plane.
		For escaping at the surface of the Moon from the Moon and the Earth, the escape speed is the square root of the sum of the squares of the separate escape speeds of 2.4 and 1.5 km/s, is 2.8 km/s.
		Thus, using the orbital speed of 1.1 km/s, a delta-v of 2.4 km/s, just enough for escaping the Moon, is more than enough to escape Earth as well.

	Pluto - Enpsychlopedia
		Pluto orbits in a 3:2 orbital resonance with Neptune.
		The discovery of Charon allowed astronomers to determine the mass of the Pluto-Charon pair from their observed orbital period and separation by a straightforward application of Kepler's third law of planetary motion.
		They have nearly circular prograde orbits in the same orbital plane as Charon, and are very close to but not in 4:1 and 6:1 mean motion orbital resonances with Charon.

	Venus (planet) (Site not responding. Last check: 2007-09-11)
		Venus has slow retrograde rotation meaning it rotates from east to instead of west to east as most the other major planets.
		(Pluto and Uranus also have retrograde rotation though Uranus' tilted at 97.86 degrees almost lies in orbital plane.) It is not known for why Venus is different in this manner it may be the result of a with a very large asteroid at some in the distant past.
		In addition to unusual retrograde rotation the periods of Venus's and of its orbit are synchronized in a way that it always presents the face toward Earth when the two planets at their closest approach (5.001 Venusian days each inferior conjunction).

	Neptune - Wikipedia, the free encyclopedia
		Comparing its rotational speed to its degree of oblateness indicates that it has its mass less concentrated towards the center than does Uranus.
		Neptune's atmosphere has the highest wind speeds in the solar system, thought to be powered by the flow of internal heat, and its weather is characterized by extremely violent hurricanes, with winds reaching up to 2000 km/h.
		With an orbital period of 165 years, Neptune will soon return to the approximate position in the sky where Galle discovered it.

		It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space.
		Neptune's atmosphere has the highest wind speeds in the solar system, up to 2000 km/h, thought to be powered by this flow of internal heat.
		With an orbital period of 165 years, Neptune will first return to the point in its orbit where Galle discovered it in 2011.

	Informat.io on Venus
		Venus has a slow retrograde rotation, meaning it rotates from east to west, instead of west to east as most of the other major planets do.
		(Uranus, and Pluto also have retrograde rotation, though Uranus's axis, tilted at 97.86 degrees, almost lies in its orbital plane.) A slow retrograde rotation is thought to have developed as a consequence of tidal forces, friction, and solar heating of Venus' thick atmosphere.
		Venus' thick atmosphere causes meteors to decelerate as they fall toward the surface, and even large meteors will strike the surface at too low a speed to form an impact crater if they have less than a certain threshold kinetic energy.

	Titius-Bode Law: Saturn
		In late September 1990, a large white spot developed, expanding over a period of weeks to encircle much of the planet's equatorial region.
		This apparent eruption of material from the lower atmosphere followed a pattern of such occurrences over a 30-year cycle, corresponding to the orbital period.
		Similar spots were seen in 1876, 1903, 1933 and 1960, close to saturnian mid-summer in the northern hemisphere.

	Elliptical Orbit - Math
		The "Angle" column is the angle that the Earth makes in relation to the sun for an elliptical orbit.
		The "Avg Angle per Day" column is what the average angle would be if the orbit were circular.
		You can see from the chart that after 10 days, the sun has drifted to the east and would take over 1 minute to reach its highest point in the sky even though according to your watch, it should be straight overhead.

	Mercury
		This is because approximately four days prior to perihelion, Mercury's orbital velocity exactly equals its rotational velocity so that the Sun's apparent motion ceases; at perihelion, Mercury's orbital velocity then exceeds the rotational velocity.
		It is possible that this magnetic field is generated in a manner similar to Earth's, by a dynamo of circulating liquid core material.
		It is also possible that Mercury's magnetic field is a remnant of an earlier dynamo effect that has now ceased, with the magnetic field becoming "frozen" in solidified magnetic materials.

		At certain points on Mercury's surface, an observer would be able to see the Sun rise twice in the same Mercurian day.
		This is because approximately four days prior to perihelion Mercury's orbital velocity exactly equals its rotational velocity, so that the Sun's motion through the sky ceases, and at perihelion Mercury's orbital velocity exceeds its rotational velocity, causing the Sun's motion in the sky to reverse.
		Four days after perihelion the Sun's normal east-to-west motion resumes.

		Both Phobos and Deimos are tidally locked with Mars, always pointing the same face towards it.
		Since Phobos orbits around Mars faster than the planet itself rotates, tidal forces are slowly but steadily decreasing its orbital radius.

		The mean orbital speed can be derived either from observations of the orbital period and the semimajor axis of its orbit, or from knowledge of the masses of the two bodies and the semimajor axis.
		is the orbital velocity, r is the length of the semimajor axis, T is the orbital period, m is the mass of the other body, and G is the gravitational constant.
		Note that this is only an approximation that holds true when the orbiting body is of considerably lesser mass than the central one.
