phase curve उदाहरण वाक्य
उदाहरण वाक्य
- The outermost planets ( Jupiter, Saturn, Uranus, and Neptune ) are so distant that only small portions of their phase curves near 0?( full phase ) can be evaluated from the Earth.
- The amplitude curve is a straight line of constant slope 20 \ alpha dB / dec, and the phase curve is a horizontal line at \ frac { \ alpha \ pi } { 2 } rad.
- A few direct measurements of the Earth's luminosity have been obtained with the EPOXI spacecraft . While they do not cover much of the phase curve they reveal a rotational light curve caused by the transit of dark oceans and bright land masses across the hemisphere.
- The asteroid was imaged by " Ralph " ( use of LORRI was not possible because of proximity to Sun ), which gave the team a chance to test " Ralph " capabilities, and make observations of the asteroid's composition as well as light and phase curves.
- Since the phase curve of Venus is relatively flat while its distance from the Earth can vary greatly, maximum brightness occurs when the planet is a crescent, at phase angle 125? at which time Venus can be as bright as magnitude " 4.9 . Near inferior conjunction the planet typically fades to about magnitude " 3 although the exact values depends on the phase angle.
