We hear and read so much about protecting and saving the planet Earth. Why should we be concerned? The simplest explanation about why the environment matters is that, as humans, the environment-the Earth-is our home. It is where we live, breathe, eat, raise our children, etc. Our entire life support system is dependent on the well-being of all of the species living on earth. It is the only home we have. Many experts believe that we can reverse some of the harm the planet has suffered. The challenge is getting enough people to take drastic enough action so that we can make a difference in our lifetime.
According to PlanetsForKids.org and FunFacts.org there are many fun planet facts for kids. Planets have fascinated scientists and humans in general for years, after all we do live on one ourselves. A planet is an astronomical object orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity. We have nine planets in our Solar System. These planets circle around the sun. The beauty of the planets found in our solar system is that they are so varied, with each one offering a new insight into everything from chemistry to physics, geography and how our solar system was formed all those years ago. Jupiter is the largest planet in the solar system, but it spins very quickly on its axis. Venus is the brightest planet in our sky and can sometimes be seen with the naked eye if you know where to look.
