What is the mean distance between the Sun and the core of the Milky Way?

A. 780 light years
B. 25 light years
C. 26,000 light years
D. 2,600 light years



Answer :

The mean distance between the Sun and the core of the Milky Way galaxy can be determined through astronomical observations and measurements. This distance is significant in understanding the structure and scale of our galaxy.

Among the given options:
- a) 780 light years
- b) 25 light years
- c) 26,000 light years
- d) 2,600 light years

Let's analyze the options one by one:

1. Option a: 780 light years: This distance is relatively short on a galactic scale and is more appropriate for describing the distances to nearby star clusters or other features within our region of the galaxy, but it is not sufficient to span the distance to the galactic core.

2. Option b: 25 light years: This distance is even shorter and only encompasses the local stellar neighborhood around the Sun. It is not nearly enough to reach the core of the Milky Way.

3. Option c: 26,000 light years: This distance is much more appropriate for the vast scale of the Milky Way galaxy. The distance to the galactic center is known to be on the order of tens of thousands of light years, making this option the most likely candidate.

4. Option d: 2,600 light years: Although larger than the previous options, this distance is still an order of magnitude smaller than what is typically measured for the distance to the galactic core.

After analyzing these options, we can conclude that the mean distance between the Sun and the core of the Milky Way is approximately:

26,000 light years.

Therefore, the correct answer is:

c) 26,000 light years.
