The nearest star to our Sun is Proxima Centauri, at a distance of 4.3 light-years from the Sun. A light-year is the distance that light travels in one year (365 days).

Part A: How far away, in km, is Proxima Centauri from the Sun?

Answer :

Final answer:

The distance from the Sun to Proxima Centauri is approximately 40 trillion kilometers.

Explanation:

The distance from the Sun to Proxima Centauri is approximately 40 trillion kilometers.

To compute the separation from Proxima Centauri to the Sun in kilometers, we want to change the separation from light-years over completely to kilometers.

In the first place, we should switch 4.3 light-years over completely to kilometers.

The speed of light is around 299,792 kilometers each second.

To change light-years over completely to kilometers, we can utilize the accompanying recipe:

Distance in kilometers = Distance in light-years × Speed of light × Number of seconds in a year

Number of seconds in a year = 365 days × 24 hours × an hour × 60 seconds

Presently, we should connect the qualities:

Distance in kilometers = 4.3 light-years × 299,792 kilometers each second × (365 days × 24 hours × an hour × 60 seconds)

Computing the worth gives us:

Distance in kilometers ≈ 40,080,595,680 kilometers

Subsequently, Proxima Centauri is roughly 40,080,595,680 kilometers from the Sun.
