Venus-watchers know that the planet has an eight-year cycle in which it orbits the Sun 13 times, with one year of that cycle spent dominating the post-sunset night skies as a brilliant “Evening Star,” and then the pre-dawn night skies as a “Morning Star.” That’s what’s happening in 2020 it’s not happened since 2012 and it won’t happen again until 2028. This coming July 2018 features a rare look at the solar system in profile: you can see Mercury and Venus low in the dusk looking westward immediately after sunset, with. Sky brightness refers to the visual perception of the sky and how it scatters and diffuses light. Why is Venus looking its best since 2012? The map also shows the phases of the Moon, and all solar and lunar eclipses. At the beginning of July, Jupiter was rising about 2 a.m. Use it to locate a planet, the Moon, or the Sun and track their movements across the sky.
