It has at least five "Neptune-like planets" lying within a distance equivalent to the orbit of Mars, making it more populated than our own Solar System in its inner region. And all the planets seem to have almost circular orbits.

So far, the astronomers have picked up clear signals from five planets, along with two slightly "fuzzier" signals. One of these possible sixth and seventh planets was estimated to be just 1.4 times the mass of the Earth; if its presence in the system was confirmed, it would be the lowest mass exoplanet yet discovered.

And how many other similar systems are out there? A few trillion?

Intensely interesting. I wish my telescopes could see them.

Certainly not within 127 LY of earth. Exoplanets are only detectable within a fairly small radius of earth with current technology, at most a few hundred light years. Inside this sphere there may be hundreds of planetary systems, but certianly not millions.
