👉 The term "outbulge" is often used in astronomy to describe an object that is larger than its parent star, and it may or may not be visible to the naked eye. The term comes from the Greek word "out," which means outside, and "bulge," which refers to a cluster of gas or dust around another celestial body. In this context, "outbulge" refers to an object that is larger than its parent star but is also visible through telescopes.
