Andromeda is a Greek mythological name for a princess who was saved from a sea monster by the hero Perseus. In English, Andromeda is often used to refer to the Andromeda Galaxy, which is the nearest spiral galaxy to the Milky Way.
Andromeda is a constellation, but because one of the best-known and most-photographed galaxies is M31, the "great nebula in Andromeda", the name is often used to refer to the galaxy. Charles Messier was a French astronomer who was a fanatic about comets. Most of his astronomical observations were done while hunting for comets. But there are a lot of faintly bright fuzzy things in the sky that are NOT comets, and Messier achieved lasting fame for his list of things that look like comets but are not comets. M31 is "item number 31" in Messier's list of fuzzy things that aren't comets.

The word galaxy is a noun used to describe a cluster of billions of stars. One way to use the word in a sentence would be to say, "The Milky Way is the galaxy of stars that we live in."

There isn't "more gravity" in the Andromeda galaxy, because that's essentially a meaningless phrase. It used to be believed that the Andromeda galaxy was larger and more massive than the Milky Way. It's still thought to be larger (in terms of the number of stars), but the Milky Way may actually be more massive. It's hard for scientists to tell how exactly how big the Milky Way is because we're inside it and "can't see the forest for the trees".

That became clear once the telescopes were powerful enough to distinguish individual stars in the galaxies. Before that, they were seen only as "nebulae" (cloud-like objects), and it wasn't clear whether M31 (for example) was part of our own galaxy. M31 is also known as the Andromeda Galaxy.

The name "Andromeda" refers to a constellation, and is often used to refer to the perhaps-misnamed "Andromeda Nebula", which is actually another galaxy, called M31. Charles Messier was a French astronomer of the late 1700s. His primary interest was in finding comets, but he kept finding things that LOOKED like comets, but turned out not to be comets. So he published his "Catalogue of Nebulae and Star Clusters" so that other would-be comet hunters would be able to easily determine that this comet-like object wasn't a comet. It turned out that the Messier catalog included many items vastly more distant, and more interesting, than mere comets. The Andromeda Nebula, or the Andromeda Galaxy, was item #31 on Messier's list. Canis Major is another constellation.
