MIR can be one of the brightest object in low Earth orbit. >I'm not an astronomers, so please forgive any faux pas... >Friday, 30 October, 19:26 SAST (GMT-2). >Bright, steady light moving S to N, about 70 degrees from >horizon (20 degrees off vertical). Passed just "below" the >"Evening Star" (Venus?). That would put it about vertical to the >Middle East, depending on orbital range? Are there polar >orbiting satellites? <snip> Cosmos 1400 reached an elevation of about 67 degrees above the horizon as seen from Pretoria at 19:25:30 SAST. It was moving from S to N. The brightest "evening star" high in the early evening sky you saw would be the planet Jupiter (not Venus). Cosmos 1400 was estimated to be as bright as some of the fainter stars in the sky (about magnitude 4.1). Cosmos 1400 is only one of many polar (or near polar) orbiting satellites (its orbital inclination is about 81 degrees relative to the equator). Satellites in polar orbits will pass directly over any point on the ground every few orbits as the Earth rotates beneath the orbiting satellite. Nick Balaskas
