Beacuse they are dimmer, but they're also bigger than the main sequence stars.
It is the Post-Main sequence star that burns helium. They are considered giants, unlike our sun, which is a Yellow Dwarf. they are extremely hot and large.
Like all main sequence stars, a red dwarf is powered by the fusion of hydrogen into helium.
No, the sun is a main sequence star, not a white dwarf. White dwarfs are the remnants of smaller stars that have exhausted their nuclear fuel and collapsed. The sun will eventually evolve into a white dwarf in about 5 billion years.
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
No, there is no dwarf star heading for Earth. The closest star to Earth is the Sun, which is a main-sequence star. Dwarf stars are common in the universe and many are much farther away from Earth.
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.

Main sequence stars are bigger.
Basically, all stars that aren't "giants", "supergiants", or "hypergiants" are considered dwarf stars. This means that all stars on the main sequence are dwarfs.
Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
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".
No, a white dwarf is not considered a main sequence star. A main sequence star is a star that is still fusing hydrogen in its core. A white dwarf is the remnant of a low to medium mass star in which fusion has stopped.
Stars can be classified into different sizes based on their mass and luminosity. The most common sizes are dwarf stars (like our Sun), giant stars (larger and more luminous than the Sun), and supergiant stars (the largest and most luminous stars, like Betelgeuse and Rigel). There are also intermediate sizes like subgiant stars.

A Main Sequence star and a White Dwarf.
Dwarf stars are NOT "so much Bright", the smaller the star is (provided it is on the main sequence) the less intrinsically bright it is.
Yes there are a few more [See related link for more information].--- Main sequence stars -----Red dwarf Yellow dwarfBlue dwarf (hypothetical)--- Degenerate stars --------White dwarf Black dwarf (hypothetical)--- Sub stellar stars -------Brown dwarf.
