Until just a few years ago, there were 9 planets in the Solar System. However, the International Astronomical Union decided that Pluto is no longer a planet, so there are now only 8 planets in the Solar System

There are currently 8 planets revolving around our sun.
1. Mercury is the innermost and smallest planet in the Solar System. Comparatively little is known about Mercury; ground-based telescopes reveal only an illuminated crescent with limited detail.
2. Venus is the second planet from the Sun. It is named after the Roman goddess of love and beauty.
3. Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System.
4. Mars is smaller than Earth and Venus. t possesses an atmosphere of mostly carbon dioxide with a surface pressure of 6.1 millibars.
5. Jupiter is 318 Earth masses, is 2.5 times the mass of all the other planets put together. It is composed largely of hydrogen and helium.
6. Saturn has several similarities to Jupiter, such as its atmospheric composition and magnetosphere. It considered to be the most beautiful planet in the Solar system aside from Venus because of the Rings.
7. Uranus is the lightest of the outer planets. Uniquely among the planets, it orbits the Sun on its side; its axial tilt is over ninety degrees to the ecliptic.
8. Neptune is slightly smaller than Uranus. It radiates more internal heat, but not as much as Jupiter or Saturn.
As we have studied in the past Pluto, considered before as a planet has been changed last 2006 with the adoption of a formal definition of planet. Pluto has a relatively eccentric orbit inclined 17 degrees to the ecliptic plane and ranging from 29.7 AU from the Sun at perihelion.
Some say there are more. Many of these planets or stars are not rotating around the sun and just passing through our Solar system. This planets does not have any gravitational pull towards the sun that's why they are not considered as a Planet in our Solar System.
