what is the biggest planet in our galaxy

[Loosehead]

Unknown but Jupiter is the biggest planet in the solar system, the presence of larger ones have been deduced in other solar systems within the Galaxy.

the problem is that plantes are very small in galactic terms and finding them, let alone wrapping tape measures around them, is very difficult. there could be huge planets out there that we havent yet seen or there might not.

GQ lup is estimated at nearly 21 times the size of Jupiter 70% the size of the sun

That's so massive it'd probably become a star if you dropped your crisp packed on it!

194 and counting

i read somewhere that is jupeter was any bigger, it could become a small star, so guess that there are not many planets bigger than that, else they would become stars.

jupiter is not quite that big. it would take a lot more mass for the gravity to get high enough for fusion to occur
