Star A appears brighter than star B, as seen from Earth. Therefore, star A must be closer to Earth than star B. Star A appears brighter than star B, as seen from Earth. Therefore, star A must be closer to Earth than star B. a. True b. False

The statement is not true always.

Explanation:

Given:

Star A appears brighter than Star B.

The apparent brightness of a star depends on two factors:

i) the distance of the star from the earth

ii) the limunosity of the star

If two stars are at same distance from the earth and one has more luminosity than other then ir appears to be more luminous. Also if two stars are at a different distance from the earth, then the star having more luminosity appears to be more luminous.

Thus, the statement is not true.
