Alecsey [184]

Hi!

The correct order would be:


Neutron Stars (Smallest)

White Dwarf

Giant Stars

Supergiant Stars (Largest)


Neutron stars are generally smaller stars that have a radius that is generally about 10 kilometers in radius, and highly dense.

White Dwarf stars have a size of about the sun, with a radius that is generally about 7000 kilometers which is nearly the same as  that of the Earth.

Giant stars are considerably larger stars with a radius that falls in a range of 10- 100 solar radii.

Supergiant stars are the largest of this selection, with radius that may lie in a range of 30 - 1000 solar radii.


Hope this helps!
