Neptune is a very interesting planet. Blue for the methane. It has an equatorial diameter of 49,500 kilometers (30,760 miles). Does have rings like Saturn, just not as glorious. Has a large spot, like Saturn and Jupiter also. Believed to be a weather pattern similar to a hurricane. If you ever think you are so busy 24 hours isn't enough time in a day, a day on Neptune is only 16 earth hours and 6.7 minutes. If mankind where on Neptune, the question wouldn't be can we go to the moon, but rather which moon do we do to. You would have 8 to choose from http://www.solarviews.com/eng/neptune.htm
I think Neptune to be home to the Blue Meanies
