Depends what type of dwarf star. - Our Sun is a yellow dwarf.
No
Many stars are bigger than the sun. In fact the sun is called a yellow dwarf, or a G dwarf star meaning it is relatively small (i.e. a dwarf) compared to the "average star" in our galaxy.
YES. A typical white dwarf star is only a bit bigger than the Earth.
The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
No Brown Dwarfs are too small to be considerred a star.
The mass of a red dwarf can go down to about 0.075 times the mass of the Sun. Anything smaller than that would be a brown dwarf, which is no longer considered a star.
There are many types of Dwarf stars - all with different diameters. Our Sun is a dwarf star! A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
The sun is a star, some stars are larger and other are smaller.
The sun is a star!
Because a white dwarf star is the core leftover from a bigger star and the core is the densest part of the star so although the star is smaller than the sun it has a similar mass as it is more dense
Pluto was redesignated as a dwarf planet. All the stars we can see are much bigger than the planets and many of them are bigger than the Sun.
A red dwarf star is smaller, dimmer, and cooler than our sun.
