Astronomical transit. Phobos transits the Sun, as viewed by the Perseverance rover on 2 April 2022. In astronomy, a transit (or astronomical transit) is the passage of a celestial body directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger ...
In astronomy, planetary transits and occultations occur when a planet passes in front of another object, as seen by an observer.The occulted object may be a distant star, but in rare cases it may be another planet, in which case the event is called a mutual planetary occultation or mutual planetary transit, depending on the relative apparent diameters of the objects.
The largest exoplanet known is HAT-P-32b which is 2.037 RJ. The smallest exoplanet known is also Kepler-42d which is 0.051 RJ or 0.57 R🜨. The densest transiting exoplanet known is CoRoT-3b, which has density of 26.4 g/cm 3; the diffusest transiting planet known is Kepler-12b, which has density of only 0.111 g/cm 3.
ICON (Explorer 96) →. Wikinews has related news: NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission.

A transit of Mercury across the Sun takes place when the planet Mercury passes directly between the Sun and a superior planet. During a transit, Mercury appears as a tiny black dot moving across the Sun as the planet obscures a small portion of the solar disk. Because of orbital alignments, transits viewed from Earth occur in May or November.
On 21 December 2012, the Cassini–Huygens probe, in orbit around Saturn, observed the planet Venus transiting the Sun. [3] On 3 June 2014, the Mars rover Curiosity observed the planet Mercury transiting the Sun, marking the first time a planetary transit has been observed from a celestial body besides Earth.

Culmination. In observational astronomy, culmination is the passage of a celestial object (such as the Sun, the Moon, a planet, a star, constellation or a deep-sky object) across the observer's local meridian. [1] These events are also known as meridian transits, used in timekeeping and navigation, and measured precisely using a transit telescope.
51 Pegasi b: In 1995 this became the first exoplanet orbiting a main-sequence star to have its existence confirmed.It is a hot Jupiter with a 4.2-day orbit. [12]47 Ursae Majoris b: In 1996 this Jupiter-like planet was the first long-period planet discovered, orbiting at 2.11 AU from the star with the eccentricity of 0.049.
