The first exoplanet that around a solar-type star

That blue dot in the upper right is Gliese 504b (GJ 504b), a giant planet that is 59 light years from Earth orbiting a solar-type star. But what is this special? Have we not already seen several extrasolar planets directly? Yes, but doing a little cheating. And is that exoplanets we have seen directly, as the system HR 8799, for example-are actually training worlds still shine with their own light, especially in infrared.
