In order to predict whether a star will eventually fuse oxygen into a heavier element, you mainly want to know what fact about the star?

Predicting whether a star will eventually fuse oxygen into a heavier element, is a process that helps to determine the mass of the star.

A star refers to a giant celestial or astronomical object that is made up of a luminous sphere of plasma, which is mainly bounded together by its own gravitational force.

Generally, a star is typically comprises two (2) main hot gases and these are:

I. Hydrogen (H).

II. Helium (He).

Some examples of a star include the following;  

In Astronomy, you can determine the mass of a star by predicting whether a star will eventually fuse oxygen into a heavier element.

In conclusion, the mass of a star is a fundamental characteristic that determines how two or more stars differ from each other.
