Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
When spacecraft like the Hubble telescope enter a planet's orbit, it is lifted by a rocket. Once it enters the orbit, the rocket drops away and the spacecraft is projected through the planet's orbit.
The Space craft was invented to enable man to explore the outer planets and galaxy's.
There is no planet named Kepler. There are, however, many planets with designations such as Kepler-22b. These planets are named as such because they were discovered using the Kepler spacecraft. The spacecraft is named after Johannes Kepler, a 16th-17th century astronomer who defined the laws of planetary motion.
No spacecraft has visited all the planets.

Asteroids, comets, minor or dwarf planets, and even some artificial spacecraft orbit the Sun but are not considered true planets.
The queen will give you the coordinates. Also, you get to design your own spacecraft.
There is no planet Kepler. Designations such as Kepler-69c are given to planets discovered by the Kepler spacecraft. This spacecraft has discovered planets ranging from 100 to 7,000 light years away.
Satellite technology is used to study planets and to watch television.
