Answer 2

Answer:

Explanation:

Three features of a star are

* brightness

Two characteristics define brightness: luminosity and magnitude. Luminosity is the amount of light that a star radiates.

*Size

Astronomers measure the size of a given star in terms of our own sun's radius. Thus, a star that measure 1 solar radii would be the same size as our sun.

*Mass

A star's mass is also measured in terms of our own sun, with 1 equal to the size of our sun. For instance, Rigel, which is much larger than our sun, has a mass of 3.5 solar masses. Two stars of a similar size may not necessarily have the same mass, as stars can vary greatly in density.
