If you want to travel from Earth to Neptune, you should first get into a low Eastward-moving orbit around the Earth. Then you must increase to beyond Earth escape speed when Neptune is on the same side of the Sun as Earth Neptune is on the opposite side of the Sun from Earth you are over Earth's night hemisphere you are over Earth's day hemisphere
