    How do we know the density of some extrasolar planets?

    Hello, How do you know how the weight of a very distant planet? How do they know this new plant would float on water. Is this science or just guessing? Weighing planets is a tricky business. We can't even see the vast majority of extrasolar planets! For most of them, all we can do is watch how...

    What kind of instruments are used to detect extrasolar planets?

    How do we know what the properties of extrasolar planets are? What type of devices are we using to know this information? The way to detect the extrasolar planets is to look at the light coming from the star, since there is no way of looking at the planet directly. The observations are based on...

    Why is our solar system so different from all the others we've found?

    I was just curious; thinking. I have read that there is evidence of other solar systems in this universe, out of these new solar systems found none resemble ours; in addition, none have included a planet similar to earth. It was said that our solar system is an "oddball". Is it possible that our...

    How can you tell the difference between single and multiple extrasolar planets?

    How do astronomers determine that they've discovered "single" large extrasolar planets and not "multiple" lesser planets? We detect extrasolar planets not by observing the planets directly (they're too small and lost in the glare of the parent star), but by observing the motion of the parent...

    Can life exist on the recently discovered extrasolar planets?

    Do you think that the new planets that have been recently found can maintain life? The new planets we are finding around other stars are detected only by way of their gravitational influence on their parent stars. We have no information on what they might actually be like, except that they are...

    Atmospheres of extrasolar planets

    In November 2001, it was announced that the first chemicals had been detected in the atmosphere of an extrasolar planet. This was done by looking at the system as the planet transited (or passed in front of) the star. The light from the star will change by a tiny amount when part of it passes...

    Hot Jupiters

    Many of the extrasolar planets known are so-called hot Jupiters. This just means that they are Jupiter sized planets very close in to the central star. The reason that so many of these types of planets have been found is that the method used to discover extrasolar planets is most sensitive to...
