Gravity is not really something for which the question "how much" can be answered.

The Andromeda Galaxy has an overall mass of about 1,500,000,000,000 times the mass of the Sun. It's possible to calculate the gravitational force attracting an outside object towards it, but you'd need to know how far away the object is.


At the distance of Earth (about 2,500,000 light-years), the force exerted by the Andromeda Galaxy on a 1-kg object is about 0.0000000000004 N. This corresponds to an acceleration of on the order of 0.001 centimeters per second per year.

Not sure what you mean exactly. Its mass is estimated at 1.5 x 10 to the power 12 times the mass of the Sun. The force of gravity it exerts will, of course, depend on the distance.

What is the next closest galaxy to Andromeda?

Canis Major Dwarf Galaxy. If you meant what's the closest spiral galaxy, then the answer is the Triangulum Galaxy.


Is Andromeda closest to earth?

If you mean the Andromeda galaxy, no, there are two dwarf galaxies that are quite a bit closer - the Magellanic Clouds.


What galaxies that most resembles own galaxy shape?

Those are the spiral galaxies. In our "immediate neighborhood" (part of our Local Group), we have M31, a.k.a. the Andromeda Galaxy.


What do scientist think all of the stars in the milky way galaxy orbit around?

They orbit around the center of the galaxy due to the galaxy's own gravity. Contrary to popular belief, the Galaxy's central black hole does not have strong enough gravity to hold the entire galaxy together as it accounts for only a tiny fraction of our galaxy's mass.


Are quasars and active galaxies cosmic cannibals?

well actually all galaxies are active, and yes they do combine after a dance across the sky, and the center of the galaxies combine, I wouldn't call it eating though because all they do is combine with each other. ______________________________________________________________________ The Andromeda galaxy is approaching our Galaxy at about 300 Km/s, and the collision between both galaxies will take place in about 4.5 billion years. Andromeda galaxy is larger in both astronomical size and number of stars than the Milky Way, although Andromeda may not be the most massive, as recent findings suggest that the Milky Way may contain more Dark Matter, and so could be most massive than Andromeda (galaxy Messier 31 or National General Catalog 224).
