03/26/2021 – Ephemeris – Venus passes beyond the Sun this morning

March 26, 2021 Comments off

This is Ephemeris for Friday, March 26th. Today the Sun will be up for 12 hours and 29 minutes, setting at 8:03, and it will rise tomorrow at 7:32. The Moon, 2 days before full, will set at 7:24 tomorrow morning.

Early this morning the planet Venus was in conjunction with the Sun. It was a superior conjunction, meaning it was out beyond the Sun. When Venus ducks between the Earth and the Sun it’s called an inferior conjunction. Here the words superior and inferior do not have their normal meanings. Inferior means inside and superior means outside. Indeed, I find inferior conjunctions far superior to superior conjunctions. For the inferior conjunction, Venus is close to us, so it appears big, bigger than Jupiter in telescopes. It only disappears in the glare of the Sun for 8 days or so. Around superior conjunctions Venus is tiny, and it disappears in the glare of the Sun for 50 or more days. Rare inferior conjunctions will see Venus cross or transit the face of the Sun.
