Tuesday September 1st the outer planet Neptune reaches a position in its orbit around the Sun when it is on the oppisite side of the Earth from the Sun. This coincidentally is known as opposition, and it is an orbital position which only the planets further from the Sun than the Earth may reach.
At opposition the object rises and sets in a fashion similar to our Moon when it is at full phase, in that the object at opposition rises at sunset and sets at sunrise.

Saturday August 15th the innermost planet Venus reaches its orbital position known as inferior conjunction. This is one of four points along an inner planet orbit, and at inferior conjunction Venus is between the Earth and the Sun – like our new Moon phase.
Tuesday October 7th the outer planet Uranus reaches a position in its orbit around the Sun when it is on the oppisite side of the Earth from the Sun. This coincidentally is known as 
Saturday 19 July at 6 UT (1 CDT) the position of the planet Mars, with respect to the Earth and the Sun, places this planet at what is called eastern quadrature. At that orbital position Mars, and actually any outer planet, is at a 90 degree angle from the Earth as this graphic shows, and the 
Mercury, the innermost planet, has reached its orbital position known as greatest eastern elongation. At that moment Mercury, the Sun, and the Earth, would be arranged in something close to approximating a right angle as this graphic shows.
On Tuesday 1 April the position of the planet Jupiter with respect to the Earth and the Sun places the solar system’s largest planet at an orbital position called eastern quadrature. Jupiter is at a 90 degree angle from the Earth as this graphic shows. Think first quarter Moon as that is a fair comparison of the relative positions. At this position Jupiter follows the Sun across the sky from east to west as the Earth is rotating, meaning that Jupiter rises after the Sun and consequently sets after the Sun.
