AI Thread Summary
To find the distance from Earth to Proxima Centauri, multiply the distance in light years (4.22) by the number of kilometers in a light year (9.461 billion kilometers). This calculation results in approximately 39.9 trillion kilometers. The discussion emphasizes the importance of understanding the conversion between light years and kilometers to solve similar problems. Eddy seeks guidance not just for this specific problem but for future mathematical challenges as well. Overall, the focus is on learning the methodology behind solving distance-related problems in astronomy.

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
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
