A solar system is a grouping of celestial bodies revolving around a star along with the structures that orbit around it as a result of gravitational forces. Cosmic bodies within the solar system include planets, moons, asteroids, comets, meteoroids, and other space debris. A highly familiar example is the Solar System comprising of the central star which is the Sun and the eight recognised planets including Mercury, Venus, our home planet, Earth, Mars, Jupiter, Saturn, Uranus and Neptune and their moons and quite a number of other objects such a dwarf planets like Pluto and other bodies in space like asteroids and comets.
6 Fun Facts About the Solar System
1. The solar system is huge, and the Earth is a very small part of it
The fact that we live on this planet makes us feel like it is a big place, but to be honest, it is just a small part of this massive system. Jupiter is the biggest planet in our solar system while Earth is one of the smaller planets.
2. The solar system has eight planets
There are a total of 8 planets in our solar system that revolve around the Sun. The names of the planets are – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earlier, Pluto was considered as a planet too but now it is only termed as a ‘dwarf planet’ as it is much smaller than its counterparts and has a completely different orbit.
Our solar system facts help us understand that there might be life outside our planet in the universe.
3. Each planet has a different temperature
While there are 8 planets, each one has unique features and has different temperatures. Venus is the hottest while Uranus is the coldest among the eight. Knowing about the planet’s temperature is an important fact about planets for kids to further understand the solar system.
4. The solar system also has many moons
Now, we all know that our planet has one moon, but did you know that Jupiter has more than 60? Other planets too have several moons are Saturn, Uranus, and Neptune. The biggest moon in the system is Ganymede and it is a satellite of Jupiter. Further, understanding the moons is one of the important facts of planets for kids.
5. There are many comets
Comets are small celestial bodies, usually made up of ice, water, dust, and other chemicals. These also revolve around the Sun and sometimes have a tail of gas or dust blown out of them. One of the famous comets is probably Halley’s Comet which can be viewed from the Earth every 76 years.
6. You can see some planets from Earth
The brightest of the planets are Mercury, Venus, Jupiter, Saturn, and Mars. This makes them visible from the Earth without a telescope. There are many other planets and celestial bodies which can be seen from time to time all around the year. These are the six interesting facts about the planet for kids.
