Uranus at opposition November 8-9, 2022

Uranus at opposition - Chart: Green slanted line of ecliptic with stars and planets labeled.
Uranus at opposition late on the night of November 8, 2022. More specifically, it reaches opposition on November 9, 2022, at 8 UTC (2 a.m. CST). At that time, it lies opposite the sun in the sky. Uranus is also at its nearest point from Earth, being over 1.7 billion miles (2.7 billion kilometers) distant. However, with the bright, waning gibbous moon glowing so closely to it in the sky, the planet will be challenging even through binoculars. In addition, the Pleiades glimmer east of the pair with reddish Mars and Aldebaran shining brightly nearby. Chart via John Jardine Goss/ EarthSky.

Earth will sweep between the sun and Uranus on November 8-9, 2022, placing the distant planet opposite the sun in our sky.

Uranus at opposition

When and where to watch in 2022: Uranus is theoretically visible to the unaided eye object – assuming you have good eyesight – and in a dark sky. The planet is easily visible in good binoculars or a telescope. By the time of its November 8-9 opposition, Uranus is rising in the east at sunset and is visible all night. It’ll remain in the evening sky through March of 2023.
Opposition for Uranus will fall at 8 UTC on November 9, 2022.
Note: Opposition marks the middle of the best time of year to see an outer planet. Uranus reaches a yearly maximum in brightness at or near opposition. From mid-October to December 1, 2022, Uranus will be at its brightest, shining at +5.6 magnitude. So it should be possible to glimpse with the unaided eye, if conditions are optimum. Think of us on Earth, sweeping between the sun and Uranus in our smaller, faster orbit. Plus, around the same time as Uranus reaches opposition, it is also making its closest approach to Earth.

Quick facts about Uranus at opposition

  • Uranus is in front of the constellation Aries the Ram.
  • The seventh planet shines at its brightest for 2022, at magnitude +5.6.
  • Uranus is at its least distance from Earth for 2022, 155 light-minutes from Earth.
  • Through a telescope, Uranus appears as a tiny, greenish disk 3.77 arcseconds across. Look for up to four moons of Uranus as well.

    How often is Uranus at opposition?

    Uranus is the seventh planet from our sun. A year on Uranus is 84.4 Earth-years long. Because Uranus’s orbit around the sun is so gigantic, and because Earth whips around the sun so quickly in comparison, Uranus’s opposition date falls about four days later each year.

    Earth and Uranus

    Our planet Earth swings between the sun and Uranus on November 9, 2022, placing us squarely in the middle of the best time of year to see this outer planet. Why? Because in early November 2022, Uranus is opposite the sun in our sky. It rises in the east as the sun sets in the west. November 9, 2022 is when Uranus reaches its yearly opposition.

    Because Uranus is opposite the sun in early November 2022, it climbs highest up for the night at midnight (midway between sunset and sunrise). So, Uranus stays out all night long. Also, around the time of opposition, Earth’s motion brings Uranus closest to Earth for 2022. The planet shines at its brightest in our sky. How bright is that? Not very bright.

    The fact is, even at its brightest, Uranus is still quite faint. It’s barely perceptible as a dim speck of light to the unaided eye, even under dark skies. At a magnitude +5.6, Uranus shines no more brilliantly than the sky’s faintest visible stars. Given a dark sky free of light pollution, you might see Uranus with the eye alone. But you’ll need to have a good finder chart to know right where to look for this distant world in front of the rather faint constellation Aries.

    Distance to Uranus

    At its closest point to Earth, Uranus is still twice as far away from us as its nextdoor neighbor, Saturn. At opposition, Uranus will be just shy of 19 astronomical units (AU) away from Earth and 20 AU from the sun. (By the way, one astronomical unit equals the average distance of Earth from the sun). Visit Heavens-Above to find out the present distance of Uranus and the other solar system planets.

    Other Uranus observing opportunities

    While opposition is mathematically the best time to view Uranus due to its nearness and brightness, another great opportunity is when the dim planet is near a brighter, closer planet, or near the moon. For example, when Venus or Mars pass close to distant Uranus as seen from our point of view, we get an easy guidepost to point us to the gas giant.

    In 2022, Uranus is quite close to the moon during the November 8 lunar eclipse, making it easy to find while the moon is in total eclipse.

    Bottom line: Uranus reaches opposition on November 8-9, 2022. At this time, it’s brightest for the year and visible to the eye under optimum observing conditions. Here’s how to see it.
