We don't need to visit - we are part of it.
That will depend on the speed of our spacecraft. At its current speed, the Voyager spacecraft will not make it out of the Milky Way galaxy within the expected lifetime of the universe, and certainly not before the Andromeda galaxy collides with the Milky Way galaxy about 3 billion years from now. In another thousand years, after we've had some time to study this, ask me again.
Galileo was the first spacecraft to visit Jupiter.
No voyager 2 or two was the only spacecraft to visit Neptune.
no
yes through wormholes
There no milky way in sky there is only milky way galaxy
It is the spacecraft voyager 2 , it is the only spacecraft to visit Neptune, and travel further.
what year did cassinni visit saturn
The Milky Way galaxy is.... called the Milky Way Galaxy
Depends on what you define as "big" or "small"... The nearest star from our Solar System, Toliman (Alpha Centauri), is 4 light-years away. This is already an incredible distance, by our standards; each light-year has almost 10 million million kilometers. It would take our current spacecraft thousands of years to reach there. The diameter of our galaxy (the Milky Way), however, is about 100,000 light-years - about 1,000,000,000,000,000,000 km., 10 to the power 18.
No.
