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 .
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 ...
It has a 2:3 orbital resonance with the planet Neptune, similar to Pluto, classifying it as a plutino. Its average distance from the Sun is 39.083 AU with a perihelion of 29.354 AU and an aphelion at 48.813 AU. Its orbit has an eccentricity of 0.249, and is inclined by 3°. The object measures about 221 km in diameter.
Distribution of mass versus orbital period for planets with a measured mass. Black lines represent the Neptunian desert. NGTS-4b is shown as a red cross.. The Neptunian desert or sub-Jovian desert is broadly defined as the region close to a star (period < 2–4 days) where no Neptune-sized (> 0.1 M J) exoplanets are found. [1]

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.

The transiting planet Kepler-19b shows transit-timing variation with an amplitude of 5 minutes and a period of about 300 days, indicating the presence of a second planet, Kepler-19c, which has a period that is a near-rational multiple of the period of the transiting planet.
