How old is our solar system compared to the universe

How old is the Solar System?

Astronomers estimate the age of our Solar System is 4.57 billion years, but how have they arrived at this number? We can tell how old the Solar System is by looking at other planets around other stars. From looking at infant planets in other systems, we know that worlds form at the same time as their stars.

How old is the universe compared to the Earth?

The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8 billion years old. Our galaxy, the Milky Way, might be a better comparison, as it is 13.51 billion years old.

How old is Earth compared to other planets?

However, scientists have also performed radiometric dating on lunar rocks and meteorites, and they all point to an age of 4.5 billion years for the solar system, including Earth and all of the other planets. Are there stars older than the universe?

What is the oldest planet in our Solar System?

Our Earth isn’t even the oldest planet in our Solar System, that would be Jupiter. The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8 billion years old.

Is the universe really 26.7 billion years old?

There was a recent paper by Rajendra Gupta of the University of Ottawa in which he argued that observations of distant galaxies with the JWST, the existence of some stars apparently older than 13.8 billion years, and a phenomenon called 'tired light', mean the universe is actually 26.7 billion years old.

How do we know the age of the Solar System?

We know the solar system’s age thanks to multiple lines of evidence. At some point in their orbits around the Sun, several small rocks from the original disk that formed the solar system have fallen on Earth as meteorites. Using extensive laboratory analysis, scientists found the oldest to have formed 4.57 billion years ago.
