This list contains the slowest-rotating minor planets with periods of at least 1000 hours, or 41 2 ⁄ 3 days. See § Potentially slow rotators for minor planets with an insufficiently accurate period—that is, a LCDB quality code of less than 2. #
(162058) 1997 AE 12 is a stony, sub-kilometer asteroid and likely the slowest rotator known to exist. It is classified as near-Earth object of the Amor group and measures approximately 800 meters in diameter. The asteroid was discovered on 10 January 1997 by the Spacewatch survey at Kitt Peak National Observatory near Tucson, Arizona [2]
In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites.
As it orbits the Sun, Venus displays phases like those of the Moon in a telescopic view. The planet appears as a small and "full" disc when it is on the opposite side of the Sun (at superior conjunction). Venus shows a larger disc and "quarter phase" at its maximum elongations from the Sun, and appears at its brightest in the night sky. The ...
Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (e.g. the Moon) and the primary planet that it orbits (e.g. Earth). The acceleration causes a gradual recession of a satellite in a prograde orbit (satellite moving to a higher orbit, away from the primary body), and a corresponding slowdown of the primary ...
[1] [2] The planet orbits the Sun in 687 days [3] and travels 9.55 AU in doing so, [4] making the average orbital speed 24 km/s. The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and perihelion distances—they are respectively 1.666 and 1.381 AU.
