Do you think that there's another planet just like ours? The Earth is a special place. It has all the things we need to live.

Chuck Said
There are no planets in our solar system like the Earth. The Earth is unique. It has all the things we need to live, such as liquid water, protection from the harmful radiation from our light-giving Sun, and oxygen to breathe.

Some people think there must be another planet like the Earth out there somewhere because there are so many planets. We've discovered more than 100 planets around the nearest stars and more are being discovered all the time.

The Earth is a very unusual and special planet. Perhaps there's another planet somewhere that's like the Earth, but there cannot be very many of them.
