A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime.
Our Sun is a yellow dwarf in "main sequence".

About 90 of all stars are what kinds of stars?
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
Are the hottest main sequence starts also the most massive?
Yes, generally the hottest main sequence stars are also the most massive. This is because more massive stars have higher core temperatures and pressures, resulting in hotter surface temperatures. Therefore, there is a direct correlation between a star's mass and its surface temperature on the main sequence.
What does main sequence mean?
The Hertzsprung-Russell diagram is a scatter graph of stars in which a star's luminosity (brightness) is plotted against its colour (temperature). Stars are not distributed all over this chart. A majority of stars lie on or near the diagonal which goes from top left (hot and bright) to bottom left (cooler and less bright). These are the main sequence stars.There are also white dwarfs which are below the main sequence whereas stars which are giants and super giants lie in the region above the main sequence.
What are some star types which are not main sequence stars?
Some examples of star types that are not part of the Main Sequence are:Red Giants, Blue Giants, Brown Dwarfs, and White Dwarfs.When stars are plotted on a chart that compares their Temperature (color) to their Brightness (Luminosity), most of them fall into a diagonal line across the chart.That chart is known as a Hertzsprung-Russell diagram and the diagonal line on it is called the Main Sequence of stars.Stars on the Main Sequence fit this pattern because they are in balance between collapse and expansion. Their gravity that is trying to collapse them is in balance with their nuclear fusion that is trying to expand them.A difference to notice between Main Sequence stars and other stars is:Main Sequence stars are dimmer if they are cooler and brighter if they are hotter.Giant stars are brighter whether they are hot or cool.Dwarf stars are dimmer whether they are hot or cool.
What are the main sequence stars also called?
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.
What are the hottest stars in the main sequence also called?
There is no specific name of such stars. In stellar models they are given the classification of O-type main sequence stars.
What kind of stars are 90 of all Stars?
main sequence stars , our sun is also a main sequence star

What is the nearest star in the main sequence is?
Most stars are on the main sequence; that includes red dwarves. Specifically, in this case, the closest known star - Proxima Centauri - is also the closest main-sequence star.

What characteristics make white dwarf stars different from main sequence stars?
White dwarf stars are much smaller and denser than main sequence stars, as they are the remnants of stars that have exhausted their nuclear fuel. They have no nuclear fusion reactions occurring in their cores and are supported by electron degeneracy pressure. White dwarfs are typically much cooler than main sequence stars, emitting most of their energy in the form of visible light rather than as high-energy radiation.
Are the hottest main sequence starts also the most massive?
Yes, generally the hottest main sequence stars are also the most massive. This is because more massive stars have higher core temperatures and pressures, resulting in hotter surface temperatures. Therefore, there is a direct correlation between a star's mass and its surface temperature on the main sequence.
Most stars are what kind of stars?
Most stars in the universe are main sequence stars. These stars are in a stable phase of their life cycle where they generate energy through nuclear fusion in their cores. The Sun is a main sequence star.
What steps in a stars life takes the longest?
The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.
