Final answer:
The Milky Way Galaxy contains roughly 200 billion stars, making option d the accurate response to the number of stars in our galaxy.
Step-by-step explanation:
The number of stars in the Milky Way Galaxy is a question that appeals to the human imagination and our quest for understanding the universe. When looking up at the sky, all visible stars to the unaided eye are part of the Galaxy; the Sun is just one among the hundreds of billions of stars within its confines. The vastness of our galaxy is made evident by the staggering amount of gas and dust it contains, enough to form billions of stars like the Sun.
Considering a galaxy is a collection of stars bound by gravitational forces and typically numbers in the billions, we can understand that our Milky Way Galaxy contains far more stars than our unaided eye can see. Specifically, within our own Galaxy, we have envisioned a sphere reaching 100,000 light-years across, encompassing its entirety. From within this sphere, we find that the Milky Way is home to approximately 100 billion stars.
The correct answer to the student's question is that the Milky Way Galaxy contains roughly 200 billion stars, making option d the right choice. It exemplifies the scope of our universe and the sheer number that makes up the celestial bodies within the Milky Way.
