This hasn't actually been done yet (we have gone to the moon, but that is technically a satellite, not a planet) but we can reasonably predict that if we ever do travel to the planet Mars, it would take something like half a year to get there. Venus would be similar although we would probably not want to go there. Other planets would take longer, since they are farther away.
it takes at least 4 months if not longer
In a special space ship.
At the moment it is not possible for a person from Earth to travel to Venus.
Ambiguous confusing results that were totally unanticipated.
The Mars rover got on Mars in these pods that opened up when they got there and then the Mars rover started building up and there are two there right now and one is called Spirit and the other is called Hope.
Its on mars! you need a rocket ship to get there!

-- If you want to send a space ship from the earth to, let's say, Mars, you need to know how Mars is going to move, so that you know what kind of transfer orbit to put the space ship into, and to be sure that Mars will be there when the ship gets there. Kepler's laws tell you how Mars moves. -- If you want to send a space ship from the earth to, let's say, Mars, you need to know how it will move once it leaves the earth and its rockets shut down. Kepler's laws tell you how the space ship is going to move. -- If an astronaut wants to put on his space suit, step out of the Shuttle, and take a little space-walk around, he'll want to know how HE will move once he's outside, so that he can be sure not to float too far away from the Shuttle. Kepler's laws tell how HE will move in his orbit around the earth.
The best thing to travel in would be a space ship. It is a long way to the planet of Mars.
