Triton is Neptune’s largest moon, and the largest moon it the solar system to orbit backwards.
Waiting in the Dark
New research hints at the presence of super-Earth planets beyond the orbit of Neptune.
Neptune All Night
In some ways, associating Neptune with the night is rather fitting. Neptune is 30 times farther from the Sun than Earth, which means the Sun appears about 1/30th the width of Earth’s sun, and about 1/1000th as bright. That is 400 times brighter than the Moon, but it is hardly what we might consider daylight bright.
