Question

Why does the Sun appear larger than other stars to us?
A.It is larger than other stars.
B.It is farther than other stars.
C.It is closer than other stars.
D.It is faster than other stars.

Answer 1

Hint: The concept that objects nearer to us appear bigger must be used to solve the sum. Because with respect to earth the closest star is none other than the sun.

Complete answer:
When compared to other stars in our galaxy or milky way it is seen that the Sun appears larger than other stars. Is Sun really larger than other stars? The answer is no. The size of the sun is nearly the same as that of any other medium sized star.
Then what might be the possible reason behind the large appearance of the Sun. In the given question we have been given four options. Let us see what can be the answer to this question.
As already discussed above, the size of the sun is similar to that of any other medium sized star so the option that it is larger than other stars will not be a correct reason for this question. Thus, option A is not correct.
The next option says that the Sun appears larger as it is farther from other stars. This is also inappropriate because we know that any far object appears to be smaller in size. Had the Sun been farther it would have appeared smaller.
The third option says that the Sun appears larger as it is closer than other stars. This is a correct option. The distance between the earth and the sun is about $147.19millionkm$ whereas the distance between the earth and other stars are about a few light years. As the sun is closer to the earth, it subtends a greater angle at the observer’s eye and hence appears larger.
We cannot say that the Sun is faster than other stars. So, the fourth option is also not appropriate.

Thus, option C is the correct answer for this question.

Note:
The mean radius of the sun is around $696000km$.
The nearest star after the Sun is known as Alpha Centauri which is at a distance of about $4.2$light years from the earth.
How do we Compare Sun With Other Stars?
Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface.
