The size n of the orbit is called the length of the corresponding cycle; when n = 1, the single element in the orbit is called a fixed point of the permutation. A permutation is determined by giving an expression for each of its cycles, and one notation for permutations consist of writing such expressions one after another in some order.
HVM 3 has a spectral range from 0.6 to 3.6 microns—it is designed to work with high sensitivity (10 nm resolution) right at the center of water's key wavelength region in infrared light (from 2.5 to 3.5 microns) with high enough spectral resolution to differentiate between forms of water.

Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the precipitation, evaporation, and cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (launched 1999) and followed by Aura (launched 2004).

On a torus, for example, it is possible to have a recurrent non-periodic orbit, [3] and three-dimensional systems may have strange attractors. Nevertheless, it is possible to classify the minimal sets of continuous dynamical systems on any two-dimensional compact and connected manifold due to a generalization of Arthur J. Schwartz.
[7]: 3 Its orbit is likely coplanar with Quaoar's equator, [15]: 1 while the entire Quaoar system is inclined by about 16° with respect to the ecliptic plane. [ 6 ] : 359 Weywot has a high orbital eccentricity of 0.14, which challenges theoretical expectations that Weywot could have formed out of a disk of material in circular orbit around Quaoar.
Q1R is located in between the 6:1 mean-motion orbital resonance with Quaoar's moon Weywot at 4,021 ± 57 km (2,499 ± 35 mi) and Quaoar's 1:3 spin-orbit resonance at 4,197 ± 58 km (2,608 ± 36 mi). The Q1R ring's coincidental location at these resonances implies they play a key role in maintaining the ring without having it accrete into a ...
