Mercury at Inferior Solar Conjunction – November 20, 2025
Time: November 20, 2025, at 14:49 IST
Event: Mercury passes between the Sun and Earth, marking the end of its evening visibility and soon becoming a morning object.
Separation: Will appear just 0°32′ from the Sun, making it completely unobservable for several weeks due to the Sun’s glare.
Perigee: Occurs at the same time—Mercury is at its closest to Earth, 0.68 AU away.
Angular size: Appears largest (9.9 arcseconds); however, it is totally unilluminated and invisible during this alignment.
Synodic cycle: This event happens once every 116 days, as Mercury transitions from evening to morning skies.
A rare behind-the-Sun moment for Mercury as it slips from view, soon to reappear in the pre-dawn sky.
