The smaller the area represented by a pixel, the more accurate and detailed the image. See resolution cell. The smallest unit of area in an image of discrete elements. The area represented by a pixel. See prograde orbit.
Revolution determines the seasons, and the length of the year.
Compare with rotation. One of six Keplerian elements, it indicates the rotation of the orbit plane from some reference point. After specifying inclination, an infinite number of orbital planes are possible. The line of nodes occurs in two places. Because the Earth spins, conventional latitude and longitude points are not used to separate where the lines of node occur.
