WHAT IS ANOTHER WORD FOR IT
1. Go to http://www.thesaurus.com/
2. Look it up.
Keep in mind there may not be a synonym for this particular word.
planetarium a building housing an instrument for projecting the positions of the planets onto a domed ceiling. planetarium an optical device for projecting images of celestial bodies and other astronomical phenomena onto the inner surface of a hemispherical dome.
lol-- that is not a word!
Also -- what is the source of your definition? Without the source or author, you are guilty of plagiarism.
