Stars are classified by four different characteristics. Apparent magnitude (brightness) and absolute magnitude (how bright it would appear at 10 parsecs from the earth). Luminosity, another measure of brightness, compares the star to the sun's brightness. Spectral classifications are measured by the star's temperatures. Finally stars are signed a number by scientists through the Morgan-Keenan System.

There are four red stars.
There are four main stars.
The four types of stars are; Main Sequence, White Swarfs, Red Giants and Super Giants. 90% of stars are in the Main Sequence.

scientists classify volcanoes in four general groups, Hawaiian, Strombolian, vulcanian, and peleean
When somebody is cleaning a fish and finds a heart with four chambers.
Triangles have only three sides; all quadrilaterals, including parallelograms, have four.
One of the features is Taxomamy. Two is something. Three is something. Four is something. Five is something.
I don't know if this is THE four ways, but here are four possible ways:Temperature/Color (amounts to the same thing)SizePopulation ("metallicity" is essentially a different description of pretty much the same thing)Mass

Virus is classified based on four characteristics. They are dimensions of capsid and virion, absence or presence of envelope, symmetry of capsid and nature of nucleic acid.
