What is the major advantage of an orbiting telescope?

a. weightless, therefore can be made very large
b. closer to the stars and planets
c. outside the atmosphere
d. costs less than an observatory

Option (C)

Explanation:

The orbiting telescopes are usually defined as those telescopes that are placed outside the atmosphere and goes around the earth. During its motion, it enables the astronomers to understand to study the solar system and other celestial objects such as the distant galaxies, the sun, the stars, other planets and how the universe is expanding, by taking images of these distant objects.

These are very costly and heavy but are more reliable as they are placed outside the atmosphere. It is because the images taken by a telescope from the earth's surface gets affected because of the atmospheric layers and its composition. So it is difficult to obtain a clear image of the distant objects. But this becomes a major advantage of using an orbiting telescope because it provides clear and distinct images.

Thus, the correct answer is option (C).
