how many planets are there in the univers?

Answer 1

Bunches. An uncountable number, for they are constantly being born and die.

Answer 2

we just don't know, we've only been finding extrasolar planets for the past twentyish years. There is said to be at least 100 Million Stars in our galaxy and if those had at least one planet which is not true but other stars compensate, we could be talking 200 Millions planets in our galaxy, multiple that by the number of galaxies out there, at about 100 million, we'll we're talking about at least a trillion trillion at the lower end of the amount. There are at the moment 8 planets in our solar system, Pluto was demoted.

Answer 3

Somewhere between 8 and infinity.

There are about 10^24 stars in the Universe.

Answer 4

A pessimistic estimate for the number of planets in the universe is nine (mercury, venus, earth, mars, jupiter, saturn, uranus, neptune, and the other unknown planet. Take note that pluto is no longer considered a planet). A more realistic estimate is about one sextillion (one followed by twenty-one zeroes
