Evening star, Barnard's Star, our star

 Venus is now the "Evening Star".  It is currently the brightest planet, at magnitude -4.

Venus, 31 Oct.  Olympus 50mm f/2 ED

Barnard's Star (circled).  01 Nov, 7:50pm MDT. Nikon 180mm f/2.8 Ai-s.

Barnard's Star is 6 ly distant and has the largest proper motion (movement relative to the more distant background stars) of any known star (10.3 arcsec/year).  It is getting some attention because of the close pass by comet C/2023 A3.  Barnard's Star is more than twice as old as our sun, and will live much longer, over a trillion years.

Our star, the Sun. 01 Nov.  AT102ED f/7 + Lunt solar wedge.

The sun is near the peak of the current solar cycle, with many active sunspots.
