Question

a) Suppose that two objects are at different distances from Earth but have the same apparent angular size as seen from Earth. What can we say about the actual sizes of the objects?A. The more distant object is smaller.B. The more distant object is larger.C. The two objects have the same actual size.

Answer 1

B. The more distant object is larger

Step-by-step explanation:

Since the chord is defined as the product of angle
`\theta` and distance radius r, if 2 objects have the same apparent angular size as seen from Earth, object with greater radius distance from Earth would yield greater product, and so is its size.
