About 1,000,000,000,000,000,000,000,000,000,000,00 years ago.
Probably when the Earth and the solar system were very young, and the solar system was still full of stray junk. In the 4 billion years since, the majority of the stuff in the inner solar system has already crashed into the Sun, Jupiter, or the Earth, or the Moon, or been thrown out of the solar system.
a dwarft planet
Nothing. You may be referring to the planet Pluto, which was DISCOVERED in 1930, but it had in all probability been part of the solar system since the Sun ignited 4.5 billion years ago.
You're in the solar system right now.You've been in the solar system since the moment you were born,and you'll be in it for the rest of your life.You can never journey to the solar system, because you're in it now,and there's no way you'll ever be out of it.
The planets in our Solar System have existed pretty much as long as the Solar System - about 4.6 billion years. Planets in other, older, solar systems may have existed quite a bit longer - almost as long as the Universe (which is 13.8 billion years old).
The best guess is that our solar system is about 8 billion years old.
Kuiper Belt objects
Billions of years. There are 2 main theories in which the universe started. The big bang theory and the solar nebula theory.A2. Our Solar System has been in its present condition since about 4.5 Gya. (Giga years ago.)The big bang the first respondent referred to was about 14 Gya.

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.
a dwarft planet
On earth- since the formation of our solar system.
The approximate age of the solar system based on the oldest rocks that have been analyzed is 4.56 billion years.
how long has Jupiter been in space
Ever since the world and the solar system were created.
About 4 and a half billion years.
