What does «galaxia peculiar» mean in Spanish?
- A galaxy of unusual size, shape, or composition. Between five and ten percent of known galaxies are classified as peculiar. Astronomers have identified two types of peculiar galaxies: interacting galaxies and active galactic nuclei. When two galaxies approach each other, their mutual gravitational forces can cause them to take on highly irregular shapes. The terms "peculiar galaxy" and "interacting galaxy" have become synonymous because most peculiar galaxies attribute their shapes to such gravitational forces.
