Detailed explanation-1: -The Milky Way galaxy is in the Local Group, a neighborhood of about 30 galaxies. Our nearest major neighboring galaxy is called Andromeda.
Detailed explanation-2: -We’ve found thousands of planets in our Milky Way galaxy, a large fraction of them in Earth’s size range and orbiting in their stars’ “habitable zones” – the distance from the star at which liquid water could exist on the surface. We know the galaxy likely holds trillions of planets.
Detailed explanation-3: -Our home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
