Question

When measuring distances, astronomers sometimes find that a small object in the sky is closer to Earth than a larger object. How can this be?

Answer 1

When measuring distances, is not uncommon for a smaller object in the sky to be closer to Earth than a larger object. This simply means that the larger object issignificantly larger than the smaller object. They try to accurately estimate the object’s distance. One way they do this is to study the light it emits. This helps them immensely.
