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.

What percentage of the universes history has earth been around?
The age of the Solar System is estimated to be about 4.568 billion years; Earth is almost as old - estimated at 4.54 billion years. The age of the Universe is estimated to be about 13.798 billion years. Thus, the ratio is about 33%.
How old is the solar system estimated to be?
It's your solar system too. Well we can use maths to work out how long it would take certain things in our and other solar systems to form, and by using models and simulations coupled with the laws of physics.
How can astronomers use rocks from the moon to estimate the age of the solar system?
14 billion years is a ball park figure for the age of the universe not the solar system. Depending on who you talk to, ages for the universe range from 11.3 billion to 13.7 billion depending on whose theory you accept. Oldest rock on the surface of the Earth date around 4.3-4.4 billion. Geologist use 4.5-4.6 billion as the age of the earth which becomes the bottom limit for the age of the Solar System. The age of the Solar system can be defined as when the Sun became hot enough to ignite, starting the fusion process. The elements of the Solar system existed long before the event of 1st light for the Sun, as the dust cloud which became our Solar System contracted forming the planets and Sun. If you call the birth of the Sun when it first gave off light-started the fusion process astrophyscists, astronomers and nuclear physicists using the law of conservation of energy and nuclear energy working backwards from calculating the mass of the sun sort of thing come up with varying answers depending on the assumptions you use. My personal guess is 5-6 billion for the Sun since 1st light.
What evidence indicates our solar system is about 4.5 billion years old?
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating.

Why scientist say that your solar system created 65 million years ago?
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.

Age of earth and other planets?
It is estimated that the Solar System is 4.6 billion years old including Earth and the other planets.

Which is older the solar system or the earth?
The Earth is part of the Solar System, so they are of the same age.
What is a planet 4.6 billion years old?
That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.

When do astronomers blieve the solar system was formed?
By studying rocks from Earth, from the Moon and meteorites it is believed that the age of the Solar System is approximately 4.6 billion years old.
Is math the same age of earth?
No. Mathematics is an invention of mankind, which is much younger than the age of the earth. But Mars, the planet, is approximately the same age as the earth according to what is known about the creation of the solar system. =)
What do meteorites reveal about the ago of the solar system?
Age of our solar system (~4.6bya)

What age is your solar system?
The approximate age of the solar system based on the oldest rocks that have been analyzed is 4.56 billion years.
