      Let me first make a correction. some decade ago, through our scientific study on Pluto, we did realise that most of it have contents and constituent of rather a steroid. we have since demoted pluto as a planet. so take from me that todate we have eight planets not nine. Back to your answer, we have studied more than 3000 planets ( by last year records). of all the planets we have discovered none of them can support life like earth. and they are very far a way. the closest in 200 light years away. what that means is that you need to travel for 200 years at the speed of light to reach the closest planet to our solar system. remember the speed of light is 300, 000 km/s

      Dear Ngrj
      Ever since the discovery of Pluto in 1930, we grew up learning about 9 planets of our solar system but since the late 1990s, astronomers argued about whether Pluto was a planet, and the International Astronomical Union ultimately decided in 2006 to call Pluto a “dwarf planet,” reducing the list of “real planets” in our solar system to eight.
      Astronomers are now hunting for another planet in our solar system, a true ninth planet, after evidence of its existence was unveiled on Jan. 20, 2016. The so-called “Planet Nine,” as scientists are calling it, is about 10 times the mass of Earth and 5,000 times the mass of Pluto.
      However, remember these are only planets associated with the STAR called the SUN, there are other Stars (suns) with thousands of planets currently estimated at 3000 known planets
      However, none of these can support life; remember, life starts with synthesis by autotrophs (photosynthesis by green plants or chemosynthesis by bacteria) and only the earth can support life
