In astronomy a phase curve describes the brightness of a reflecting body as a function of its phase angle. The brightness usually refers the object's absolute magnitude, which, in turn, is its apparent magnitude at a distance of astronomical unit from the Earth and Sun. The phase angle equals the arc subtended by the observer and the sun as measured at the body.

  • Em astronomia, uma curva de fase descreve o brilho de um corpo refletor como uma função do seu ângulo de fase. O brilho normalmente é referido à magnitude absoluta do objeto, que, por sua vez, é a magnitude aparente à distância de uma unidade astronômica da Terra e do Sol. O ângulo de fase é igual ao arco subtendido pelo observador e o Sol, medido no objeto. (pt)

  • In astronomy a phase curve describes the brightness of a reflecting body as a function of its phase angle. The brightness usually refers the object's absolute magnitude, which, in turn, is its apparent magnitude at a distance of astronomical unit from the Earth and Sun. The phase angle equals the arc subtended by the observer and the sun as measured at the body. The phase curve is useful for characterizing an object's regolith (soil) and atmosphere. It is also the basis for computing the geometrical albedo and the Bond albedo of the body. In ephemeris generation, the phase curve is used in conjunction with the distances from the object to the Sun and the Earth to calculate the apparent magnitude. (en)
