Hello! Welcome to the international space station!
You are the Alien. We are from Earth.
Where is this and what is Earth?
We are in our Solar System. It is located within the Milky way galaxy, which is a barred spiral galaxy, we are located about 2/3 of the way outwards from the middle of the galaxy. Our solar system formed about 4.6 billion years ago. The three closest stars to our sun (our solar systen revolves around the sun) are the main sequence stars Alpha Centauri A and B aswell as Proxima Centauri. Proxima Centuri is a red dwarf star but the Alpha Centauri stars are just regular main sequence stars much like our sun. They are both about 4.3 lightyears from the sun
Fascinating! What exactly is in this solar system of yours.
