dwarf planet pluto, eris, sedna and particles in kuipers belt were the last once to be discovered. There are still more planets outside our solar system which were discovered late but I have not mentioned them here.

Most of the discoveries never make the news. I read somewhere on line there are about 3000 or so at this point, many of which are theoretical as the stars have a measured wobble from the tug of a planet but they are too distant to get a planet photo clearly. Others like Gleise C are a little closer and clear enough to sort out information, then there are the close ones in out own systems outskirts. On an average, it is a daily event now, for the most part.

It is in all the news. A planet recently found orbiting star Gliese 581 is at the right distance from that star to be at a temperature where life could exist. So far it has no name, only the catalog number Gliese 581 c. It is about 5 times the mass of Earth, but that is about all we know about it. It cannot be seen and was only detected by the Doppler shift it causes in the light of the star that it orbits.
