    The universe is made up of many billions of galaxies, The Sun (Sol) is one star of billions in the Milky Way galaxy, the Earth is one planet (of eight) orbiting that star.

    The links above will give you lots of information.

    Can you state your question a little more clearly? Do you want to know the Earth's distance from the center of the Milky Way? The Earth is actually INSIDE the Milky way, orbiting its center.

    Capuchin,
    Just to add to your list.
    The newly proposed Planet List will be:
    Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Charon, UB313, Ceres

    However, I'm certain UB313 Will gain a new name eventually...
    Pluto will be downgraded to an icy mass. Part of the Trans Neptunian area...

    Planet Definition:
    The object must be in orbit around a star, but must not itself be a star.
    It must have enough mass for the body's own gravity to pull it into a nearly spherical shape.

    Actually I don't think charon is even a dwarf planet, it's simply still classified as a satellite of pluto.

    Ballenger, I did BOLD that point

    The Earth is IN the galaxy...

    Think of a ball, that would be the universe. Now imagine the inside, filled with billions of galxies. We are one of thos galaxies of stars, and in that galaxy, there is the Earth... The Earth truly is a speck of dust

    Its not a ball exactly, although there are star groups called globular clusters (that consist of about a million stars each), that exist above and below the plane of the milky way galaxy's spiral disk.

    The disk of the Milky Way Galaxy is about 100 million light years in diameter. We are in that disk about 33,000 light years from the center of the galaxy. Our solar system actually revolves around the center of the galaxy. It takes about 250 million years to make one revolution.

    We can not see to the center of the galaxy because it is too densely populated with stars. Some believe that there is a black hole there.

    If we were to leave the galaxy, we would no longer be surrounded by stars. The night would appear to be very black with faint patches of barely visible light. These would be distant galaxies. The closest spiral galaxy to us is the Andromeda galaxy, which is 2 million light years away, or about 20 Milky Way diameters away from us.

    A light year is about 26 trillion miles.

    Did you know that according to the science we believe today, that it is possible to travel to the Andromeda Galaxy for a visit? You could go in your life time 2 million light years if you had a ship that could travel very close to the speed of light. The only problem would be by the time you got back to Earth, billions of years would probably have elaped, and your dog would not be around to greet you!

    Actually, whether we can see to the center of the galaxy depends on what wavelength we're looking at. I agree that we can't "see" the galactic center if you are talking about optical light. But it's quite possible at, for example, infrared wavelengths.

    Here's a link to an animated gif of some of the stars at the galactic center:
    UCLA Galactic Center Group

    This is from work done by Andrea Ghez's group at UCLA. The group's work makes it possible for us to make a stronger statement than above. I'd go so far as to say that it's highly likely there's a black hole at the center of our galaxy. The animated gif shows the stars orbiting around it.

    Have you noticed that while the learned sages of this site are providing answers to a question that is vague, at best, the original poster has yet to acknowledge the responses. I was thinking about providing the following answer: Even though the moon is less than 1/2 the size of the Earth, it is still much further away.
