there are 8 planets in the solar system. originally there were 9 but Pluto is considered a planetoid because its too small to be a planet
The space between planets is known as interplanetary space. It is mostly vacuum but can contain small amounts of particles and gases.
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
They study how long to get to planets and if there is life in outer space.
The space between planets is mostly empty, containing small amounts of gas, dust, and debris. This region is known as interplanetary space. Additionally, various celestial objects such as asteroids and comets can be found between planets.
There are 7 main classification of Planets. They are classified into the following groups; * Inferior Planets * Superior Planets * Inner Planets * Outer Planets * Terrestial Planets, * Jovian Planets * Gas Giants

Because they are to small to be considered planets.
Space was born with planets we don't live in like Mars, Sun, And Jupiter. It need other planets to help keep Space alive forever. It can't just have Earth.
Because Planets are one of the only types of celestial bodies able to fill space, and they are being held in space by gravity. if you want a scientific answer, the big bang would be the reason planets are in space. if you want a religious answer: God put them there.
To see if Life can survive in space or on planets.
