What is the difference between Milky Way galaxy and Andromeda Galaxy?

The Andromeda galaxy contains about a trillion stars. The Milky Way has about 300 billion stars. Stars from both galaxies will be thrown into new orbits around the newly merged galactic center.

How is the Andromeda Galaxy different from other galaxies?

Unlike the globular clusters of the Milky Way, which show a relatively low age dispersion, Andromeda Galaxy’s globular clusters have a much larger range of ages: from systems as old as the galaxy itself to much younger systems, with ages between a few hundred million years to five billion years.

How are Andromeda and the Milky Way similar?

Both the Milky Way and the Andromeda galaxy (M31) are giant spiral galaxies in our local universe. Instead, they found that our nearest galactic neighbor is more or less the same mass as the Milky Way — some 800 billion times the mass of the Sun.

What is bigger Andromeda or Milky Way?

By some estimates, the Andromeda Galaxy contains roughly one trillion stars. That’s significantly bigger than the Milky Way, which more recent estimates suggest is 150,000 light-years across (though the exact boundary of where either of these galaxies “end” is a bit nebulous).

Will Milky Way and Andromeda collide?

In roughly 4.5 billion years’ time the Milky Way will smash into the rapidly approaching Andromeda Galaxy, and astronomers are still attempting to predict what it will be like when the two galaxies collide. That a collision between our galaxy and the Andromeda Galaxy is inevitable has been known for a little while.

What is the closest galaxy to Earth?

Distance Information The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
