Neptune at 2019 Opposition

   Tuesday September 10th the outer planet Neptune reaches a position in its orbit around the Sun when it is on the opposite 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 an object orbiting the Sun beyond Earth’s orbit 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.
   Neptune is over the eastern horizon after sunset local time and with an apparent magnitude of 7.81 is beyond unaided-eye visibility but could be visible with large aperture telescopes or with a camera.
