No, there are thought to be billions of planets just in our galaxy alone. Then there are billions of galaxies. There are 7 other planets in our own solar system alone.
Earth is the third planet from out sun, but there is no way of ordering Earth with planets in the entire universe as there are other solar systems. Scientists can only make an educated guess as to how many.
no because scientists think that earth is the only planet in the universe that supports life :3
Earth is currently the only planet where it is known that beings can exist. However in my opinion the universe is so unthinkably huge that there must be another planet where there are the right conditions for life.
It is the only place in the known universe that has been verified to contain intelligent life.
Scientist study earth because earth is the place that we envolved on and is the only planet in our solar system that is know to support life and is the fifth- largest planet in our universe.
Earth? You might need to be a bit more specific in your question
Earth- since so far, it is the only planet that has a combination of gravity, temperature, water and atmosphere where people can live.
Considering that earth is not the only planet in the universe and that are many other planets in this same universe, it would almost be egotistical to believe that we are the only inhabitants in the universe on this single planet called Earth. As our technology has advanced to the point of visiting other planets, it would also be egotistical to believe that we are the only beings in the universe with the intelligence to travel among the other planets. It makes sense, therefore, to assume that yes, there could very likely be aliens on the earth either in the future or possibly even in the now.
Earth is the third planet from the Sun, located in the Milky Way galaxy. It is the only known planet to support life, due to its unique combination of atmosphere, water, and temperature. Earth occupies a tiny fraction of the vast universe, yet it is significant to us as our home.
1, Ours......
Uranus, with an average temperature of -355 degrees Fahrenheit and -215 degrees Celsius.
our planet earth has its own theory.... base on my scientific search, our planet started when the matter of the universe explode... and the left particles... started to grow with the help or the other elements of matter in the universe...
