In our model, Neptune is .59 inches in diameter, and 1478 meters from the Sun.

These images of Neptune combine observations made with the Hubble Space Telescope and NASA's Infrared Telescope Facility on Mauna Kea, Hawaii. They capture blustery weather -- monster storms and equatorial winds of 900 miles per hour -- in Neptune's atmosphere.

Bright areas in these images indicate the presence of clouds.

Does Neptune emit radio waves?
