 '''கேலட்டி''' (''Galatea'') அல்லது '''நெப்டியூன் VI''' என்பது [[நெப்டியூன்|நெப்டியூனுக்கு]] மிக அருகில் இருக்கும் நான்காவது [[உள் துணைக்கோள்]] ஆகும். 
 இது ஒழுங்கற்ற வடிவமும் 158 கிலோ மீட்டர் விட்டமும் உடையது. 1989-ஆம் ஆண்டு [[தேசிய வானூர்தியியல் மற்றும் விண்வெளி நிர்வாகம் (ஐக்கிய அமெரிக்கா)|நாசா]] அனுப்பிய [[வொயேஜர் 2|வாயேஜர் 2]] [[விண்ணுளவி]] இதனைக் கண்டுபிடித்தது.&lt;ref&gt;{{citation|author=AMIA|year=1999|title=Transforming health care through informatics}}&lt;/ref&gt;&lt;ref&gt;{{Cite journal |last1=Belyakov |first1=Matthew |last2=Davis |first2=M.
