They really can't guess, since it was obviously millions of trillions of years since the Big Bang, which formed the Earth and began the Universe expanding. But not everyone believes in the big bang religious beliefs say that God created the Earth and the Universe.
The Solar System is believed to be around 4.5-4.6 billion years old.
Our solar system is thought by astronomers to be about four and a half billion years old.
Scientists estimate the age of our Solar System to be around 4.7 billion years old. They base this on observations and light spectrometry of the Sun.
Pluto has been declined as a planet because of its size it is the smallest planet in the solar system that scientists have found.
I think Venus is about as old as the rest of the solar system.You may mean the surface of Venus.The surface is relatively young.Scientists believe thisbecause there are relatively few impact craters.
No. Scientists think that the solar system was created from the remains of a star that blew apart between 4.5 and 4.4 billion years ago. Almost no object in the solar system would be older than 4.4 billion years old. There may be an odd piece somewhere from a star that blew apart earlier but scientists have never found any indication of such a piece. It is thought that the Universe itself is between 13 and 14 billion years old. According to current theory, nothing in the universe is 200 billion years old.
Scientists believe that the sun is around 4.6 billion years old. This age is determined through the study of the formation of the solar system, the analysis of age-dating techniques for rocks and meteorites, and the use of computer models.
4.5-5 billion years old
Our solar system is thought by astronomers to be about four and a half billion years old.
Scientists estimate the age of our Solar System to be around 4.7 billion years old. They base this on observations and light spectrometry of the Sun.
The Universe is at least twice as old as the Solar System
The sun is 4.5 billion years old
About the same age as the time of formation of the solar system: 4.6 billion years to 4.7 billion years.
Our solar system is almost 5 billion years old.Our solar system is almost 5 billion years old.Our solar system is almost 5 billion years old.Our solar system is almost 5 billion years old.
