Final answer:
The distance to the nearest star from the Sun is About 4 light-years, which corresponds to answer C. Proxima Centauri is the nearest star to our Sun, approximately 38 trillion kilometers away.
Step-by-step explanation:
The distance to the nearest star from the Sun is About 4 light-years. This means the correct answer is C. About 4 light-years. Light-years are used to measure the vast distances in space because stars are incredibly far apart. Our Sun is separated from Proxima Centauri, the closest other star, by about 4 light-years, which is roughly 38 trillion kilometers. To put that in perspective, light from the Sun takes about 8 minutes to reach Earth and about 4.1 hours to reach Neptune. Meanwhile, a light-year is approximately 9.46 trillion kilometers, the distance that light travels in one year.
It's interesting to note that the brightest star visible in the U.S. night sky without a telescope is Sirius, which is a little more than 8 light-years away, while light from our Sun reaches us in about 8 minutes. This coincidence in numbers highlights the vast difference between the astronomical unit (AU), which is the distance from the Earth to the Sun, and the light-year, a much larger unit used for measuring the enormous distances between stars.
