Question:

The size of our Solar System is about a few dozen _ _ _ _

a) light-years

b) solar diameters

c) light-hours

d) light-seconds.

Solar system

The solar system is the family of the Sun, planets, and the satellites of the planets, asteroid, meteoroids, and comets.

Millions of solar systems are present in our galaxy called Milky Way.

Answer and Explanation:

The solar system is a family of Sun, Stars planets and other heavenly objects in space near the sun.

Generally, the distance between the heavenly objects are expressed in light-years.

If we use the other smaller units the numerical figure will be more which is not appropriate.

So the size of the solar system is about 0.5 to 1 light-years as suggested by the Astronomers.

The option (b), (c) and (d) are not appropriate units because these units are very smaller to measure the size of the Solar System.

So we have only one appropriate option for the size of the Solar system which is option (a).

Hence the size of our Solar System is about a few dozen light-years.
