For those of us who believe dwarf planets should be counted as a subclass of planets, the latest status is that our solar system now has 13 planets: four terrestrial planets, four jovian planets, and five dwarf planets.
We do not know how many planets there are in space. But the answer would be in the Billions or trillions. The International Astronomical Union (IAU) recognises eight planets in our solar system (from closest to sun to furthest); Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
