That they all fall on the main sequence.
The Pleiades is a open star cluster. It contains mostly blue-white type stars, so the colour of the cluster would appear to be blue-white. However, it is a cluster and not a single star. See related question.
That is called the HR diagram (Hertzsprung Russell) and the temperature is along the horizontal axis while the vertical axis is the star's absolute magnitude. Each star has a fixed point in this diagram, and it shows that most stars belong in a broad band on the left called the Main Sequence.
The answer to this question is Hertzsprung-Russell diagram
The closest star to Betelgeuse is approximately 643 light-years away. This star is located in the star cluster known as the Orion Nebula, where it is part of a group of young, hot stars.
The Beehive Cluster (Praesepe) is an open cluster in the constellation Cancer.It is not a single star.
The Star-Delta control circuit diagram shows the delta contact and the main contact.
A star cluster is a cluster of stars, so clearly a star cluster must be larger.
Because of the high percentage of OB stars, the cluster is a relatively young cluster. M26 has an estimated age of only about 25 million years.
The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).

Palomar 1 is located in the northern hemisphere, specifically in the constellation Cassiopeia. It is a star cluster situated at a distance of approximately 6,500 light-years from Earth. The cluster is notable for its relatively young age and is associated with a region of star formation.
The Beehive Cluster (Praesepe) is an open cluster in the constellation Cancer.It is not a single star.
Star clusters provide a way to study the evolution of stars because they contain stars of different ages. By analyzing the attributes of stars in a cluster, astronomers can observe how they change over time, providing insights into the various stages of stellar evolution. Comparing the properties of stars within a cluster, such as their temperature, luminosity, and composition, allows astronomers to track their evolution from formation to eventual demise.
