For objects orbiting a concentrated mass (e.g. the planets orbiting the Sun), the orbital speed goes down as we go outward from the Sun because the distance is increasing, but the total mass enclosed (essentially the Sun's mass) is constant. In the case of a galaxy, the total mass enclosed grows with ...The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way.It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.Andromeda has a diameter of about 46.56 kiloparsecs (152,000 light-years) and is approximately 765 kpc (2.5 million light-years) from Earth.The galaxy's …average density the universe would need for gravity to someday halt the current expansion if dark energy did not exist.
