Question
Chapter 7, Problem 1CC
To determine
The number of stars in our solar system.
Expert Solution & Answer
Answer to Problem 1CC
Solution:
There is only one star in our solar system that is called the Sun.
Explanation of Solution
Introduction:
Our solar system consists of a Sun, planets (like the Earth, Mars, and Jupiter), smaller objects like satellites (moons), asteroids, comets, trans-Neptunian objects, and a huge amount of dust.
Explanation:
Earth’s Solar system has eight planets and a Sun along with a variety of smaller celestial objects like the Moon, which is the only natural satellite of the Earth. It also consists of asteroid belts holding a huge number of asteroids and loads of dust, comets, etc. A star is the heart of a solar system and in our solar system, it is the Sun. The second closest star to Earth is the Proxima Centauri, but that is outside our Solar system.
Conclusion:
Thus, the Sun is the only star present in our solar system.
