Now how many PLANETS are there in universe??

I know that pluto is no longer considered a planet but I've noticed that galaxy, unviverse, and solar system keep being used interchangeably, but they're not the same. The universe is the biggest of the three as it still stand as not having a measurable volume, its to vast. Next are galaxies which are clusters of trillions of stars that are atrracted together by gravity and span many trillions of lightyears and then in our galaxy is the solar system which is a very tiny tiny tiny part of our galaxy which is were our 8 planets,previously 9 reside.

Pluto is no longer considered a planet but there are more discoveries made of celestial bodies which are more likely canditates to being classified as planets in our solar system. One newly discovered is considerably bigger than Pluto and is called 2003 UB313 which may likely be named planet Xena in the near future.

Are u sure? I Just knew that...Thanks for your information. I will check that.

There are lots more planets that are being discovered orbiting other stars. Not sure what the count is at the moment though.
