What is Earth's galaxy address?

Answer 1

Our galaxy is part of the Local Group which consists of more than 30 other galaxies.
But E.T. might send mail to: Earth, The Orion-Cygnus Arm, Local Spur, right off The Sagittarius Arm, Milky Way, about 25,000 light years (give or take 1,000) from center. It will take some time to arrive. See link for available postcard designs.

Answer 2

it all depends from where you are asking. in general, earth is fixed around the sun, so the sun's space address is more useful. if you know that the sun is in the Orion arm of the milky way galaxy, then you can see that earth is the third planet from the sun, and 1 AU from the sun defined as astronomical unit the earth-sun distance.

we are never fixed in one constellation as we move through space, but from our closest neighbors(Alpha Centauri, Sirius, Procyon etc), we (the Sun) appears as a 1st magnitude star in the Orion constellation or there abouts.

Answer 3

Earth is located in the Milky Way galaxy. Its address within the Milky Way is estimated to be about 27,000 light years away from the galactic center, in one of the spiral arms of the galaxy known as the Orion Arm or Local Arm.

Answer 4

Earth, The Orion-Cygnus Arm, Local Spur, right off The Sagittarius Arm, Milky Way, about 25,000 light years (give or take 1,000) from center.

Answer 5

The Solar System (which includes Earth) is located in one of the spiral arms of the Milky Way galaxy.
