Southern Sky in November: MercuryMars Meet‑Up, Jupiter’s Retrograde, Saturn Well Placed

The best targets are the gas giants, with fleeting twilight appearances from Mercury and Mars.

Overview

  • Mercury and Mars share the western twilight in early November and reach a close conjunction on November 12 before both slip into solar glare mid‑month.
  • Mercury shows a slim crescent and is best around November 12 at about 9 arcseconds and 22% illumination ahead of its November 20 inferior conjunction.
  • Jupiter rises late in Gemini at roughly magnitude −2.4, begins apparent retrograde motion on November 11, and spans about 42 arcseconds for detailed telescopic views.
  • Saturn stands high toward the north in the evening with a 19‑arcsecond disk and a 42‑arcsecond ring system tilted only about 0.4°, shining near magnitude 0.8.
  • Venus stays essentially unobservable from mid‑southern latitudes, while the 9th‑magnitude Seyfert galaxy M77 in Cetus offers a timely deep‑sky target that has recently crossed the celestial equator due to precession.
