Which is the youngest planet in solar system?

Answer 1

Oooh, ineresting one! Depends what you mean by youngest. The actual matter was all made in the time after the Big Bang. More specific elements were made in a previous supernova explosion. Our sun is a second or third generation star and so the planets around it are made from the accretion disk formed during the formation of the solar system. From that point of view, all the planets could be said to have the same age!

However, if you mean the surface structure, then there are a few contenders. Earth's surface (along with the surface of our moon) are believed to be the product of a massive celestial collision millions of years ago which actually melted the entire surface of the earth! This then cooled and solidified, forming the crust. This therefore means the surface of earth could be considered relatively young.

Another contender is the Gas Giants. They're never really the same. They have similar structures within them but their internal structure and outer enormous storms are ever-changing and so it could be said that they are eternally young.

Pick the one that sounds most likely. Most people will say that they're all as old as each other. What do you think?

Answer 2

Uranus is the seventh planet from the Sun and is considered the youngest planet in the solar system.

Answer 3

They are all about the same age.
