Distance to the planets & their atmosphere once you do get there.
Earth is the only habitable planet around.
Basically it comes down to time and logistics let's say that we want to travel to Jupiter at a velocity of 40,000 mph it would take 1.5 years to get there so we have to stock enough supplies and oxygen for at least 4-5 years, fuel is another issue fuel to accelerate slow down and maneuver, communications if you arrived at Jupiter and had a problem in the ship and sent a radio transmission to Earth it would take you roughly 93 minutes to get a response perhaps too late. Micro bursts, radiation, asteroids, micro-meteorites, gamma rays, etc....Not making that trip anytime soon
there are many problems for future travel to neptune,because it is so far away from the sun,it would be very cold.Plus neptune is very far away,and we only live a average of 75 or 90ish at the max,mabye more by a few years,so by the time a human got there they would be dead.We could send in a robot with camera's to study and bring back samples though.
they can not get to close because they do not no if its safe and the dont no if its got rings or not
the main problem is non-availability of oxygen.
because neptune not hard it is soft
what
it is not help full
traveling into space, there r planets and junk
what do you mean use other planets?
no thunder does not appear in other planets
they want to see why other planets are differant from earth and want to learn and study other planets!
So far there has not been a trace of life on any other planet in our solar system. Earth is the only planet with life. Life is unsustainable on other planets because they are either too hot , too cold, no water, poisonous gasses, and a variety of other problems.
They make their living by traveling to other planets in their TARDISes and earning jobs there.

it was Kepler
No. Mercury and Venus have no moons.
the mars invent is the spaceship that they use for traveling this planets.
what do you mean use other planets?
Yes.
they had poor traveling conditions Integrating and/or understanding the culture, language, and customs of the other country.
The other planets are not similar to dwarf planets.
