Which one of the objects listed below has the largest size.
a-globular clusters
b-galaxies
c-stars
nebula
I think is B please help
To find out which one of the objects listed has the largest size, we need to understand the relative sizes of these objects.
1. Globular clusters: These are spherical collections of stars held together by gravity. Globular clusters typically contain thousands or even millions of stars. However, their size is relatively small when compared to other galactic structures.
2. Galaxies: Galaxies are enormous systems consisting of stars, gas, dust, and other celestial bodies bound together by gravity. They come in various sizes, ranging from small dwarf galaxies to giant elliptical galaxies and spiral galaxies. Galaxies can be millions or even billions of light-years in size.
3. Stars: Stars are massive, luminous spheres of plasma held together by their own gravity. Compared to galaxies, stars are relatively tiny. The size of stars can vary, with some being much larger than others. For example, the largest known star, UY Scuti, has a radius over 1,700 times that of the Sun.
4. Nebulae: Nebulae are large regions of interstellar gas and dust that can be found throughout galaxies. They come in various shapes and sizes. Some nebulae, like the Orion Nebula, can be visible to the naked eye, while others may only be observable with powerful telescopes.
Based on the given options, galaxies are the largest in size among the objects listed. So, your answer of option B (galaxies) is correct.
