 '''கெப்ளர்- 25''' ''(Kepler-25)'' என்பது  இலைரா என்ற விண்மீன் குழுவின் வடக்கில் உள்ள ஒரு [[விண்மீன்]] ஆகும்.னிது சூரியனை விட சற்றே பெரியது. ம் சூரியனை விட 2 1/2 மடங்கு ஒளிரும் தன்மை கொண்டது. இது 10.6 என்ற  தோற்றப் பொலிவு பருமை கொண்டுள்ளதால் வெறும் கண்ணால் பார்க்க முடியாத அளவுக்கு மங்கலாக உள்ளது.

 கோள் வட்டணைகள் விண்மீனின் நடுவரைத் தளத்தில் 7{{±|8}}° கோண வேறுபாட்டில் அமைகின்றன
