You'll probably find Neptune a little bit cold for you. The average temperature of your new home is a frigid -353 F. Of course that's without calculating the windchill from your planet's 900 mph winds. You may wish to try and live inside the planet (it does have an internal heat source). Make sure to pack a lifetime supply of oxygen before you leave though. Fortunately, Neptune's gravity is relatively similar to Earth's. It's a little stronger though, and you'll probably feel pretty sluggish for the first couple months. If I had sent you to Mars, you would have dealt with a gravity half as much as Earth.

I hope you aren't really keen on birthdays, because you'll be lucky to live for just 1/2 of a Neptune year. In fact it hasn't even been a Neptune year since the planet was discovered in 1846.

Neptune is an average size planet. However it could still hold about 80 of our puny Earths. Your planet will be too big to have one government, so plan on having smaller cities and countries. I wouldn't plan on a world of Neptune-Marts in every shopping center, but your planet probably will be at least partially homogenized. Eventually you should become more technologically advanced than your Uranus neighbors, but the smaller Pluto may actually become king of your universal jungle. You'll want to make nice with them. Enjoy your new home!
