The best guess is that our solar system is about 8 billion years old.
Earth has been a part of the solar system for its entire existence. It formed in roughly its current orbit about 4.58 billion years ago.
Earth, but there could have been water in Mars years ago.
The earth - and the other seven planets, comets, asteroids and minor planets - are all "charter members". They've been in the solar system since it evolved out of the accretion disc around the proto-sun about 4.5 to 5 billion years ago. Creationists, on the other hand, believe that the solar system and universe have been in existence for around 6,000 - 10,000 years.
About 1,000,000,000,000,000,000,000,000,000,000,00 years ago.
Astronomers believe that the solar system is about 4.6 billion years old. This age is determined by studying the ages of rocks on Earth and meteorites from space that have been dated using radiometric dating techniques.
Meteorites have generally been around since the formation of the Solar System, over 4 billion years ago, until they happen to collide with Earth.
Meteorites are "space rocks" which have fallen to earth. Because these bodies have been in space for billions of years, likely since the formation of our solar system, they have not been subject to any type of weathering, erosion, or other degradation that happens here on earth. So, they're "pristine" examples of what things were like in our solar system 4+ billion years ago.
The approximate age of the solar system based on the oldest rocks that have been analyzed is 4.56 billion years.
Jupiter has been in space since the formation of the solar system, which is estimated to be around 4.6 billion years ago. It is one of the oldest celestial bodies in our solar system and has been orbiting the Sun for billions of years.
There are currently 8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) in our solar system, with Pluto having been demoted to dwarf planet a few years ago.
