Cool, in comparison with other stars.
An Astronomer is a scientist who studies the stars and planets.
Scientists consider a red star to be a type of star that has a relatively low surface temperature, typically ranging from about 2,500 to 3,500 degrees Celsius. These stars emit light primarily in the red and infrared wavelengths, giving them their characteristic color. Red stars are often classified as red dwarfs or red giants, depending on their size and stage in the stellar lifecycle. They are generally cooler and less massive than other types of stars, like yellow or blue stars.
Small red stars are called red dwarves. They are the least luminescent and coldest stars.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
Red stars can be smaller or larger than blue stars as there are two types of red star. Red dwarfs are much smaller than blue stars while red giants are much larger than blue stars.

Scientist consider hypothesis to be an educated guess on what they are studying. If that scientist researches and experiments more, he will see if his hypothesis is true or false.
