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.
The length of a cycle is the number of elements of its largest orbit. A cycle of length k is also called a k-cycle. The orbit of a 1-cycle is called a fixed point of the permutation, but as a permutation every 1-cycle is the identity permutation. [7] When cycle notation is used, the 1-cycles are often omitted when no confusion will result. [8]
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).
With a diameter of about 5,270 kilometres (3,270 mi) and a mass of 1.48 × 10 20 tonnes (1.48 × 10 23 kg; 3.26 × 10 23 lb), Ganymede is the largest and most massive moon in the Solar System. [45] It is slightly more massive than the second most massive moon, Saturn's satellite Titan, and is more than twice as massive as the Earth's Moon.
Ro dives into the link between winter and erectile dysfunction, including reasons why it happens and possible solutions.
Orbital forcing is the effect on climate of slow changes in the tilt of the Earth's axis and shape of the Earth's orbit around the Sun (see Milankovitch cycles).These orbital changes modify the total amount of sunlight reaching the Earth by up to 25% at mid-latitudes (from 400 to 500 W/(m 2) at latitudes of 60 degrees).
