Tonight – October 19, 2017 – the planet Uranus, the 7th planet outward from the sun, is at opposition. In other words, our planet Earth in its smaller, faster orbit swings in between the sun and Uranus today, placing Uranus opposite the sun in our sky.

Because Uranus is opposite the sun, Uranus rises in the east at sunset, climbs highest up for the night at midnight (midway between sunset and sunrise) and sets in the west at sunrise. Not only does Uranus stay out all night long, but this world is now coming closest to Earth for the year and shining at its brightest best in our sky.

But even at its brightest, Uranus is still quite faint. It is barely perceptible as a dim speck of light to the unaided eye. At a magnitude of 5.68, Uranus shines no more brilliantly than the sky's faintest stars. Given a dark sky free of light pollution, you might see Uranus with the eye alone – but only if you know right where to look for this distant world in front of the rather faint constellation, Pisces.

As good fortune would have it, this year the new moon – a moon most nearly between the Earth and sun for this month – falls on October 19, too, at nearly the same hour that Uranus reaches opposition.

takyon: The opposition peaks during the day in the U.S. (October 19, 17:21 UTC), so maybe try it on both nights.

      For the 19th:
      01h 38m 26s +09° 35’ 29”

      Location of Uranus. So you can find it with both hands, or a telescope with setting circles.
