4.6 billion years old.
Ceres is pretty much the same age as most other objects in the solar system: about 4.6 billion years.
The oldest objects in the solar system whose age has been measured are small grains of dust known as calcium-aluminum-rich inclusions (CAIs) found in meteorites. They are believed to have formed within the first 2-3 million years of the solar system's history. This makes them some of the oldest solid materials known in the solar system.
Most objects in the solar system are the same age. The Sun being slightly older than the planets. However, there may well be other molecules that were around when the Sun formed that will be much older than the Sun.
No one knows it. Scientists lie or exaggerate about knowing. Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.
Comets are made up of remnants from the early solar system, so their age is generally around the same as our solar system, approximately 4.6 billion years old. While some comets may contain even older material from beyond our solar system, as a whole, comets are not older than our solar system.
Age of our solar system (~4.6bya)
The approximate age of the solar system based on the oldest rocks that have been analyzed is 4.56 billion years.
The Solar System is about 4.6 billion years old.
The Earth is part of the Solar System, so they are of the same age.
They don't. Do some reading on the Solar System (for example, in Wikipedia); the current estimate for the age of the Solar System is between 4-5 billion years.They don't.

They tell us the age of the moon, which indicates when the Solar System itself was being formed.
That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.
