Addendum

Evening planets

Evening planets visible at 10 p.m. August 1st, 2018. Also shown are the zodiacal constellations and the ecliptic. The ecliptic, which is the plane of the Earth’s orbit and near where than rest of the planets appear because the solar system is pretty flat. Also note that Venus, which will reach greatest eastern elongation from the Sun on the 17th, is not very high above the horizon. That’s because the ecliptic meets the horizon at a shallow angle. In spring Venus would be very high on the west. The projection shows Venus and Mars a bit higher in the sky than they actually are. Click on the image to enlarge. Created using Stellarium.
