How many planets revolve around the sun in our solar system.?

In the Solar system, all planets revolve around the Sun.


CHECKING with people who believe in astrology,

In that case I suggest that you repost at the Horoscopes forum. This forum is about astronomy, not about astrology.


astrology,since its discovery many planets have been seen.

Astrology (as well as astronomy) was invented, it wasn't discovered.
Outside of the solar system, about 700 planets have been discovered so far. http://exoplanet.eu/catalog.php

If you are checking with people who believe in "Astrology" then you are in the wrong place. I think your question was not placed in the correct category. This is astronomy and space. Don't let the Yahoo! Answers system automatically select your category. Most times it will go where you did not intend it. but instead It has to do with the ridiculous superstition of astrology, not the science of astronomy.

There are 8 planets orbiting the Sun in our Solar System. We used to believe it was 9, but recently Pluto has been reclassified a dwarf planet.

And yes, scientists and observers have found numerous planets orbiting other stars. It's really exciting stuff! Here is the Wikipedia page on Extrasolar Planets:
