A phase correction is applied to observations of _______________.
AI Explanation
The correct answer is B) planets.
A phase correction is applied to observations of planets, but not to observations of the Sun or stars. Planets exhibit a phase, like the Moon, as they orbit the Sun. This phase needs to be accounted for when making observations of a planet's position for navigation purposes. In contrast, the Sun and stars are so distant that they appear as point sources without a discernible phase. Therefore, a phase correction is not necessary for observations of the Sun or stars.
