Our Solar System and Planets
A planet is a large ball of rock or gas that revolves around a central star. The Earth, the planet we live on, is the only known planet to contain life. The central star that the Earth orbits is the Sun. In total, there are 8 planets orbiting the Sun.
These planets, their moons and other objects orbiting the Sun make up our solar system. In order of their distance from the Sun, the four closest planets are Mercury, Venus, Earth and Mars. These planets are called the inner planets. They are made up mostly of rock. Due to their close distance to the Sun, the inner planets are also much warmer than the planets further from the Sun.
The outer planets are the four furthest planets from the Sun - Jupiter, Saturn, Uranus and Neptune. These planets are much larger than the inner planets. They are not rocky like the inner planets. Instead, they are made up mostly of gases. They are often referred to gas giants.
Besides Mercury and Venus, all of the planets on the solar system have one or more moon. Our planet, Earth, has just one moon. Mars has two moons. The planet with the most moons is Jupiter. It has 79 moons. Its largest moon, Ganymede, is larger than the planet Mercury!
Earth is the only planet in the solar system known to contain life. Why is this so?
Fun Fact : Although Mercury is the closest planet to the Sun, Venus is the hottest planet in our solar system! This is because of the make up of its thick atmosphere. During the day, the temperature on its surface can reach more than 440 degrees Celsius.
Did you know?
Scientists once considered there to be nine planets in the solar system. This included a small icy planet beyond Neptune, called Pluto. In 2006, scientists decided that Pluto was too small to be considered a planet and classified it as a dwarf planet.

Alright! Imagine a group of kids on a playground, and they’re all playing a game of "Planet Tag". Now, each kid represents a different planet, and they all have special rules about what makes them a "planet". Some years ago, there were 9 kids in the "Planet Tag" game: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and little Pluto. Each of them was called a planet, and they all played together in the same solar system playground. But one day, the playground monitors (they're the astronomers!) looked closely and noticed that little Pluto was a bit different from the other kids. They noticed three main things: Size: Pluto was much smaller. It’s not just small but also less massive. Imagine Pluto being a toddler among teenagers! Where it Plays: Pluto didn’t play in the same area of the playground as the bigger kids (planets). It played in a different corner with its own group of friends, called the Kuiper Belt, where there are lots of other small, icy objects. How it Plays: All the other planets had cleared their own paths, kind of like when you run around in tall grass and make a trail. But little Pluto’s path was messy, because it’s not big enough to clear its own way. So, the playground monitors (astronomers) got together and thought about it. They decided to create a new rule that to be in the "Planet Tag" game, you needed to: Orbit the Sun: Go around the Sun in a path (Pluto does this!) Be Round: Be shaped like a ball (Pluto does this too!) Clear Your Path: Have your own clear path where no other kids (objects) are playing (Pluto doesn’t do this 🙁) Because little Pluto didn't clear its own path, the monitors said it couldn’t be in the "Planet Tag" game as a planet anymore. But don’t worry! Pluto wasn’t left out completely. It got to join a new game with its Kuiper Belt friends called "Dwarf Planet Tag". So, Pluto is still a very important part of our solar system playground, just in a different game! And that's why, kids, Pluto is not called a planet anymore but a dwarf planet. It’s still special and we still love to study and learn about it!

Where was Pluto

In 2006, the International Astronomical Union (IAU) reclassified Pluto as a "dwarf planet." The IAU came to this conclusion because Pluto does not meet the criteria for being a planet. In order for an object to be classified as a planet, it must: -Orbit around the Sun -Be massive enough to have pulled itself into a spherical shape -Not be massive enough to have ignited nuclear fusion in its core -Not have cleared the neighborhood around its orbit Pluto does not meet the third criterion because it is not massive enough to have pulled itself into a spherical shape. Instead, it is shaped more like a potato. Additionally, Pluto does not meet the fourth criterion because it has not cleared the neighborhood around its orbit. There are many other objects, including asteroids and comets, that share Pluto's orbit.
