Hi, my name is Eddy and this is my first post on the forum. I like math but do not know a lot of it. I am hoping to find some help and guidance her on how to solve things i don't find an answer to online.

This is the problem at hand

The average distance from Earth to Moon is about 384,403 kms. The sun is the closest star to Earth and is about 150 million kilometers away. the next closest star is Proxima Centauri which is about 4.22 light years away from Earth. A light year is defined as 9,461billion kilometers. Find and label the distance in kilometers from Earth to Proxima.

I would appreciate if the person who decides to help me would explain how to go about doing a problem like this. Much more than an answer i need to learn what to do when face with this types of problems.
thank you so much. i can't tell you how much i appreciate any help. I can't do or show any effort on my part other than take out the data given because I am really lost at sea here,
Thanks,
Eddy

The sun is the closest star to Earth and is about 150 million kilometers away.

The next closest star is Proxima Centauri which is about 4.22 light years away from Earth. [1]

A light year is defined as 9,461billion kilometers. [2]

Find and label the distance in kilometers from Earth to Proxima.
Do you "see" that you only need :
[1] Proxima Centauri is 4.22 light years away from Earth.
[2] A light year is equal to 9,461 billion kilometers.

Earth to Proxima = ? kilometers

## 1. What is the average distance from Earth to Proxima Centauri?

The average distance from Earth to Proxima Centauri is approximately 4.22 light years, which is equivalent to 25 trillion miles or 40 trillion kilometers.

## 2. How is the average distance from Earth to Proxima Centauri calculated?

The average distance is calculated by taking the distance between Earth and Proxima Centauri at its closest point (4.22 light years) and its farthest point (4.37 light years) and finding the average of those two values.

## 3. How long does it take for light to travel from Earth to Proxima Centauri?

Since light travels at approximately 186,282 miles per second, it would take about 4.22 years for light to travel from Earth to Proxima Centauri.

## 4. Is the average distance from Earth to Proxima Centauri constant?

No, the average distance can vary due to the gravitational pull of other celestial bodies and the movement of both Earth and Proxima Centauri in their respective orbits.

## 5. Why is the average distance from Earth to Proxima Centauri important to know?

The average distance is important because it helps us understand the vastness of space and the distances between celestial bodies. It also plays a role in space exploration and the potential for interstellar travel in the future.
