the nearest one is 90 million light years away
Dwarf stars are died stars , they are about the size of earth and has a temperature of about 10 000 C (18 000 F).

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.
Red and White dwarf stars.
Astronomers measure distances from Earth to stars using a method called parallax, which involves observing the apparent shift in a star's position as Earth orbits the Sun. They also use techniques like spectroscopy and standard candles to estimate distances to stars that are farther away.
Stellar distances, like the distances of stars and galaxies from Earth
Light Year is unit for all astronomic distances
Dwarf stars are hard to find because they are small and faint compared to other types of stars, making them more challenging to detect with telescopes. Additionally, dwarf stars are abundant in the universe, but they are typically located far away from Earth, making them difficult to observe in detail.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
Astrometry: The study of the movement of the stars relative to the position of the Earth to determine precise measurements and distances from the Earth to those stars.

There is no distance from earth, as all the stars are at different distances!:))
