    Hi Logan,

    Other galaxies, like ours, contain billions of stars. Many of these are similar to the Sun. We don't know yet if they have planets around them, but we have started discovering that many stars in our galaxy have planets, so that is probably true in other galaxies as well.

    cheers,

    Terry

    How big are the planets that orbit these stars? And how small is the smallest galaxy?

    Scientists have found planets of lots of different sizes orbiting other stars. The larger ones are easier to detect, so most confirmed detections are of planets larger than Earth -around the size of Jupter or a bit bigger. The smaller ones are probably out there, thoough.

    If you are intersted in exoplants you might like to look at these web sites:

    http://exoplanets.org/

    Hmm, the smallest galaxy?

    Here is an article about the smallest yet found, at least as of 2007:
