The question makes no sense. The Earth is a big ball of rock and metal, it doesn't "know" anything.
Zero. We are in it
Earth is part of the Milky Way, so yes there is. As to whether there is any other life out there, we do not know.
The galaxy that contains Earth and the rest of the Solar system is the Milky Way galaxy.
No,it can't be.Because ,as you know,the Milky Way has two spiral arms extending from it,and the sun is found on one of these spiral arms.And as the earth is found in the solar system,so it's impossible that earth is in the centre of the Milky Way.
I know that we are near the edge. (It is round.) Does that help? (It is much more dense in the middle; that is what you see at night when you see "the Milky Way" - the middle there-of.)
It is very easy. Since the Earth is in the Milky Way, you don't even have to move to get to the Milky Way.
Milky Way Galaxy, Sun, Earth
No. The earth is inside of the milky way Galaxy.
Zero. Earth is in the Milky Way Galaxy.
Interestingly, it doesn't matter whether you prefer the answer in kilometers,in miles, or in inches. The exact figure is still zero. Earth is IN the Milky Way.
The Earth is inside the milky way galaxy. It's our own galaxy.
Yes, scientists know what is outside the Milky Way Galaxy. We know that the Andromeda galaxy is outside the Milky Way. The Andromeda is 300 million light years away from earth, and we have also mapped several stars, too.
