they are all roughly the same age. the planets began forming when the sun was born, approximately 5 billion years ago. they were made from lots of dust and rocks that all came together to form bigger rocks, and eventually, planets!

The interesting bit about planet formation is that there really should be a planet in-between Mars and Jupiter. It is thought as Jupiter is so massive that the planet that tried to form couldn't and that is why we have the asteroid belt there - the remnants of what could have been a planet.
I would agree with most others on this topic, the Earth is estimated to be around 4.5 Billion years old and one would think that there would be a difference of around 1 million years between the main 8 planets - Inner planets tend to form first within a system due to increased gravity

Yes, the planets of our Solar System were all formed at the same time and we only need to compute the age of just one of them, say, the Earth and it's the same for every planet, right? But as this age cannot be computed directly from materials that are solely from the Earth, we have to use samples of meteorites.
So we now know that the age of the Earth and the planets is around 4.5 billion years old.
