There do exist orbits within these empty regions where objects can survive for the age of the Solar System. These resonances occur when Neptune's orbital period is a precise fraction of that of the object, such as 1:2, or 3:4. If, say, an object orbits the Sun once for every two Neptune orbits, it will only complete half an orbit by the time ...
Precovery image of 2003 XV 93 taken by the Palomar Observatory in 1992 [8] 2002 XV 93 is locked in 2:3 resonance with Neptune, meaning that for every two revolutions it makes around the Sun, Neptune makes exactly three. [2] The rotation period of this object is currently unknown.
These objects are in a 2:3 mean-motion orbital resonance with the planet Neptune meaning, for two orbits a plutino makes, Neptune orbits three times, and are therefore protected from Neptune's scattering effect. Plutinos are located in the inner ridge of the Kuiper belt, a disk of mostly non-resonant trans-Neptunian objects. [1] [3]
[3] 2001 KU 76 has a semi-major axis of 45 AU and an orbital period of about 302 years. [1] It has been observed 29 times over 6 years and has an orbit quality code of 4. [1] The libration of 2001 KU 76 's nominal orbit. Neptune is the white (stationary) dot at 5 o'clock. Uranus is blue, Saturn yellow, and Jupiter red.
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.
These trojans have a semi-major axis and an orbital period very similar to Neptune's (30.10 AU; 164.8 years). 2008 LC 18 belongs to the trailing L 5 group, which follow 60 ° behind Neptune's orbit. It orbits the Sun with a semi-major axis of 30.056 AU at a distance of 27.7–32.4 AU once every 164 years and 9 months (60,186 days).
Naiad / ˈ n eɪ ə d /, (also known as Neptune III and previously designated as S/1989 N 6) named after the naiads of Greek legend, [10] is the innermost satellite of Neptune and the nearest to the center of any gas giant with moons with a distance of 48,224 km from the planet's center. Its orbital period is less than a Neptunian day ...
Laomedeia / ˌ l eɪ ə m ə ˈ d iː ə /, also known as Neptune XII, is a prograde irregular satellite of Neptune. It was discovered by Matthew J. Holman , et al. on August 13, 2002. [ 6 ] Before the announcement of its name on February 3, 2007 (IAUC 8802), it was known as S/2002 N 3 .
