What are the 9 planets in order?

The nine planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto (though Pluto is now classified as a dwarf planet).

Order of the Planets

1. Mercury: Closest to the Sun, smallest planet.
2. Venus: Brightest planet, similar in size to Earth.
3. Earth: Our home planet, the only known planet with life.
4. Mars: Known as the Red Planet due to its iron-rich soil.
5. Jupiter: Largest planet, a gas giant with strong storms like the Great Red Spot.
6. Saturn: Famous for its beautiful rings made of ice and rock.
7. Uranus: An ice giant, rotates on its side.
8. Neptune: Farthest planet, very cold and windy.
9. Pluto: Once the ninth planet, now reclassified as a dwarf planet in 2006.

Why Pluto Was Reclassified

In 2006, the International Astronomical Union (IAU) set new rules for what defines a planet. According to the definition, a planet must:

1. Orbit the Sun.
2. Be spherical in shape.
3. Clear its orbit of other objects.

Pluto failed the third condition because it shares its orbit with other icy objects in the Kuiper Belt. So it is now officially a dwarf planet.
