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.

The things an ocean engineer is to consider in building a fish tank for a salt water fishery list are:
- The Water supply
- The Water quality.
- The Climate.
- The Hydrological characteristics.
- The Soil characteristics.
- The Land.
<h3>What are the basic element for fish farming?</h3>
They are:
- Land
- Water
- Capital
- Market
- Management skills
Before the ocean engineer will build, he will need to consider or look into these requirements as it is one that will help them to be able to plan and create the fish tank.
Note also that Ocean engineers are people who are said to be involved in the act of designing, building, testing of different kinds of tools or equipment and as such the things an ocean engineer is to consider in building a fish tank for a salt water fishery list are:
- The Water supply
- The Water quality.
- The Climate.
- The Hydrological characteristics.
- The Soil characteristics.
- The Land.
