This paper deals with the problem of astrometric determination of the orbital elements of the outer planets, in particular by assessing the ability of astrometric observations to detect perturbations of the sort expected from the Pioneer effect or other small perturbations to gravity. We also show ...
ET, according to EarthSky, the moon will be almost perfectly aligned with the sun and Earth, causing the outer edge of Earth’s shadow, known as the penumbra, to be cast onto the glowing orb. The moon looks slightly darker during a 2023 penumbral lunar eclipse...
