Answer:
The most likely explanation is that the star is a member of an eclipsing binary star system.
Explanation:
An eclipsing binary star system takes place when two stars which are close to each other move in an orbit in which sometimes, one star can hide the light behind the other.
There are two types of eclipses depending on the orientation of the orbit and the size of the stars: the totals or the annular ones. It may also be the case that the eclipses are partial.
<em>Algol </em>is the best known eclipsing binary star, and the first of this kind to be discovered. Its interval between eclipses is 173 hours (2.9 days).
When this type of eclipses happens, the brightest star provides 92% of the light of the system, while the eclipsed only contributes less than 8%, and there is a third star, which is not eclipsed.
Therefore, if there is any star that has been bright most of the time, and during certain time intervals it becomes dimmer, that star is being overshadowed.
Some of the consequences are that many of the animals especially lions fishes elephants might die. more people will die due to contamination in the air especially in the city of los angeles,mexico city,beijing,tokyo and other huge populated cities. oceans mite rise such as in places in miami florida new york city amsterdam in the netherlands and in venice italy and we lost many islands i n the pacific island due to seas rises in the past 10 years such as nuatumbu island
