neptune is the eighth planet from the sun . Comment: You can get as close as you like, but you would need a very good spacecraft and it would take years to get there.
To date, no satellites or robots have directly explored Neptune. However, the Voyager 2 spacecraft flew by Neptune in 1989, providing the first and only close-up images and data of the planet.
Only one through 2009. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton and discovered 5 new inner moons.
Mostly for the same reason you stay close to the surface of the planet - gravity!
Mars is the red planet, because it looks red on close approaches. The next close approach will be in the spring of 2014, you can have a look at it then.

the spacecraft will be pulled in towards the center or core of the planet....although it has the possibility to be magnetized, the spacecraft won't be magnetized if it didn't enter the territory of the planet..... because a planet was considered to be a "giant ball of magnet"..
Good question. Imagine a spacecraft is approaching a planet. The planet is moving around the sun. The spacecraft path is adjusted to approach the trailing limb of the planet -- the rear edge of the planet when you look at its orbit around the sun, not its dark side. The planet pulls on the spacecraft as it goes by (and actually the spacecraft pulls on the planet, too). If the spacecraft were close enough to the planet, and traveling slowly enough, it would be captured by the planet. But it is possible to put the space craft in a path so that will not be captured--it can be pulled by the planet so that the spacecraft gains velocity. The planet loses velocity, but since planets are huge and spacecraft small, the planet's velocity is barely affected. It is hard to visualize this, but imagine a ping pong ball being struck by a soccerball in mid-air (this would make a good science class demonstration)--the ping pong ball will pick up tremendous speed by being struck by a heavier ball. The heavy ball will hardly notice it. You can do this by dropping the soccer ball with the ping pong ball on top of it. Slingshotting a spacecraft (also called gravity assist) works in a similar way except the spacecraft would be pulled by the planet's gravity instead of being pushed (as with the two-ball demonstration).
The first of two spacecraft to visit the planet was Mariner 10, which mapped only about 45% of the planet's surface from 1974 to 1975. The second is the MESSENGER spacecraft, which mapped another 30% during its flyby of January 14, 2008. MESSENGER will make one more pass by Mercury in 2009, followed by orbital insertion in 2011, and will then survey and map the entire planet.
it cant get very close
the spacecraft is the MESSENGER i the spacecraft is the MESSENGER i
the spacecraft was able to get very close to Europa's surface.
Uranus
In spaceflight jargon it means when a spacecraft or satellite passes close enough to an object in space (typically a celestial body, such as a planet) to gather scientific data without orbiting or landing on the object.
if a planet was to close to the sun it would burn up
Mariner 4
The Barcelo Marina Palace is a four star Cuban hotel. It is located in Varadero, a well known tourist area, close to the Marina Gaviota. The marina is one of the most important in Cuba.
