On 29 May 2016, a very rare “green moon” will be visible in the night sky.
For those who need information on how this works … All night long on Sunday, May 29th the seventh planet from the Sun, Uranus, will park itself near the moon.
The green giant is only 4 degrees away from the moon. The cosmic odd-couple will appear about four degrees apart in the sky—equal to 8 full moons side-by-side.
This week after darkness falls the near full moon acts as a convenient guidepost for finding Uranus. The green-colored ice giant has four times the width of Earth, but since it lies nearly 1.9 billion miles (3.1 billion kilometers) away from Earth, it’s barely visible to the naked eye — and only in very dark, pristine skies.
With the glare from the nearby moon, binoculars will be your best bet in spotting Uranus. Just look for a tiny greenish-blue disk in the field of view. By the way, the absorption of light by methane in the atmosphere is what gives Uranus it’s cool Didula nanayakkara coloring.
