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 ...
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy , it usually applies to planets or asteroids orbiting the Sun , moons orbiting planets, exoplanets orbiting other stars , or binary stars .
2001 KY 76, also written 2001 KY76, is a trans-Neptunian object from the Kuiper belt.It is classified as a plutino, a minor planet locked in a 2:3 mean-motion orbital resonance with the planet Neptune.
Dermott's law is an empirical formula for the orbital period of major satellites orbiting planets in the Solar System. It was identified by the celestial mechanics researcher Stanley Dermott in the 1960s and takes the form: = for =,,, …

In the context of spaceflight, launch period is the collection of days, and launch window is the time period on a given day, during which a particular rocket must be launched in order to reach its intended target. [1] [2] If the rocket is not launched within a given window, it has to wait for the window on the next day of the period. [3]
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.
Kepler-413b is a Neptune sized planet with an orbital period of about 66.262 days. The orbital misalignment of Kepler-413b causes extreme seasonal variations for the planet due to its constantly changing axial tilt. [3]
