These "early ideas" don't go back that far, since Neptune wasn't discovered until the mid 19th Century.
It was supposed from the beginning to be pretty much the twin of Uranus, and things haven't changed much since. Its only "alteration" has been a temporary demotion from Last Planet, made in 1930 and corrected with the redesignation of Pluto as "dwarf planet."

How many moon are for Neptune?

For a project in science class you have to make a commercial for living on Neptune. Any ideas?
Yes get to know neptune... If the gravity's low - good for basketball. If the temperature is low - good for skating you get the picture... Get to know neptune.
What is good ideas to put in a paper about Neptune?

The planet Neptune appears blue, due to the presence of methane in its atmosphere which absorbs red light and reflects blue light. It also has faint, narrow rings surrounding it.
What does the retrograde motion of neptune's moon Triton indicate about its origin?
Because Triton revolves around Neptune opposite its rotational direction it is considered retrograde. This indicates that it was likely a planetoid that was captured by Neptune's gravity rather than having formed in orbit around Neptune.
