We’re not quite alone in our Milky Way, we may think of ourselves as Aliens, we travel each day on our spaceship at about 721,000 km/h and 935,000 km/h depending on the day of the year as I have found in this website http://www.urban-astronomer.com/astronomy/how-fast-is-the-earth-travelling-through-space/ so between 17304000 km/day to 22440000 km/day around the Galaxy, that means that we won’t be in the same spot we were yesterday for ~250 million years, but we’re not lonely, we have stars all around us, to keep us company in this huge univers, and that’s not all, our galaxy is traveling at about 1080000km/h so 25920000km/day. It’s breathtaking isn’t it?
Now as we’re all aware, this isn’t the only galaxy around, we have a bunch them around, this are the closest ones:
|38||Triangulum Galaxy (M33)||SAc||2.64 ||0.81||−18.87||6.19||Local Group||Most distant (difficult) naked eye object||60,000 l|
Two of these will collide with the Milky Way, M31 and M33 which their real name is Andromeda and Triangulum.
Milky Way and Andromeda are traveling toward each other at 400 000 km/h, so unfortunately we need 4 billion years for them to collide. But really it will be a splendid view!
Maybe we’ll be able to see them from heaven? Hope so.
