Vertimas - Rumunų-Anglų - Asi vrea sà fiu o stea sà stràluceacà numai pt...

"Aş vrea să fiu o stea (care) să strălucească numai pt tine"= "I'd like to be a star that twinkles only for you";
"să ajung în cer"= "to get to heaven /sky";
"k şi pe pământ există raiul, dar numai lângă tine"= "that also on Earth there is heaven, but only close to you/ near you.
Those ideas are closer to the text, but your text also catches the meaning.

I'd say "that there is Heaven on Earth as well"... I just think it sounds better.

oh and maybe "to get into heaven"? heaven as a place? considering that heaven has gates?
