The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
dwarf stars,giant stars,main sequence stars
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.
"main sequence" is the tern.
Of the stars you can see from Earth, 90% are in the main sequence.
main sequence stars , our sun is also a main sequence star

Beacuse they are dimmer, but they're also bigger than the main sequence stars.

The main sequence is a line on a Hertzsprung-Russell diagram, on which every star is placed on a graph of absolute magnitude against surface temperature. Each star produces a dot on the diagram, and all the main sequence stars fall roughly on a straight line. On the main sequence the hot bright stars are on the top left and the cooler dimmer red stars are on the lower right. The Sun is just above halfway up.
It isn't different. The sun is hotter and brighter than the average main sequence stars, but it is within what is considered normal. There is nothing extraordinary about the sun itself.

It can have many different sizes. Only the largest giants are no longer main sequence stars.
There are billions of stars that are not on the main sequence.
Of the stars you can see from Earth, 90% are in the main sequence.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
By definition and experiance sol as a main sequence star and as a class planet earth and the earths moon with some comets as life as we know it. But a star like a gas giant its gravity may be to strong. Sol as a main sequence stars has the right gravity for earth and counter clock wise rotation and gravity
Supergiants develop when massive main-sequence stars run out of hydrogen in their cores. They then start to expand, just like lower-mass stars, but unlike lower-mass stars, they begin to fuse helium in the core almost immediately.
