Question

How do galaxies range in size? A from dwarf galaxies with approximately 1 million stars to giant galaxies with more than 1 trillion stars B as large as the distance from Earth to the sun and back C from the smallest speck of dust to infinity D from as small as the Milky Way to as large as the universe​

Answer 1

I think the answer is A. from dwarf galaxies with approximately 1 million stars to giant galaxies with more than 1 trillion stars.

The size of galaxies are measured by the number of stars the galaxies contain, and by the total mass and size.

Answer 2

Galaxies range from a few thousand to a million light-years in diameter. A galaxy is a cluster of stars, dust, and gas which is held together by gravity. Galaxies are scattered throughout the universe and they vary greatly in size. A galaxy may be alone or it may be in a large group of galaxies called a "supercluster".
