The Solar System is our home, the place that Earth resides and is basically our neighbourhood. It is pretty incredible and as far as we know, currently, it is unique in that it is the only system we have knowledge of that supports life. Pretty Amazing!
The Universe is rather large and consists of an innumerable amount of galaxies, The Solar System where we live is a part of the Milky Way Galaxy. It is packed full of planets, moons, comets and lots of mystery. We have landed on the moon and even sent robots to live on Mars and report back to us on what they find. Most recently NASA started receiving data and photographs from the New Horizon mission, all the way from Pluto.
We know a lot about our solar system but, there is still a lot to discover and new missions are starting all of the time, explorations into the unknown to fill our craving for knowledge. In March there is a new NASA mission that leaves for Mars, called Insight and it aims to discover more about what is below the surface of the red planet.
The Sun is at the center of our system, the planets, dwarf planets and other celestial bodies within the gravitational pull of the Sun, orbit the star. Within it there are 8 planets, of course that is not counting poor Pluto who has been classified and declassified many times, now we should refer to it as a dwarf planet, of which we have five that are known, there is the potential for hundreds more though.
How do dwarf planets differ from planets? The simple answer is that whilst they orbit the Sun dwarf planets have not cleared their immediate orbit of objects, where as planets have.
Planets themselves each have a gravitational field that attracts natural satellites or moons towards them. For example the Earth has one satellite, The Moon. In total there are 173 planetary moons, Jupiter alone has 67 and Saturn 62.
