How many planets in ower solar system are discovered?
There is always a possibility but your question is impossible to answer with certainty until such a discovery is made. Discovering new planets is pretty tricky but infinitely easier than predicting the future. If we knew how many more planets there were to be discovered in the Solar System then we would have already discovered them. It seems highly unlikely that any more planets that are discovered will be regarded as “true planets” as even Pluto has now been declassified as a true planet, leaving 8 recognised “true planets”. Pluto and its smaller binary companion Charon, together with the yet un-named body beyond are now known as “dwarf planets” and any further bodies are likely to be similarly classified.
