The term transit or astronomical transit has three meanings in astronomy:
A transit is the astronomical event that occurs when one celestial body appears to move across the face of another celestial body, hiding a small part of it, as seen by an observer at some particular vantage point. If the first celestial body hides a major part, or all of, the second celestial body, then it is an occultation rather than a transit.
A transit occurs when a celestial body crosses the meridian due to the Earth's rotation, about halfway between rising and setting. For instance, the Sun transits the meridian at solar noon. Observation of meridian transits was once very important for timekeeping purposes (see transit instrument).
The term star transit is used for the passage of a star through the eyepiece of a telescope. Precise observations of elevation or time are carried out to determine star positions or the local vertical (geographic latitude/longitude).
The rest of this article refers to the first kind of transit.
“Now that Act 89 funds have dried up and COVID stimulus funds are ending, mass transit agencies around the state have hit financial difficulties, forcing astronomical cuts in service and higher fares to ride,” the Senate minority leader wrote.

During K2-18b's stellar transit, Webb was able to detect some starlight being absorbed into the planet's atmosphere that left clues for astronomers to piece together the gases in the atmosphere.

A frontal system is defined as the transition zone where different types of masses of air with contrasting characteristics, primarily temperature and humidity meet, Pagasa weather specialist Rhea Torres said.
