depends on the speed:
closest object:moon
time today: aprox 3 days
light speed:aprox 1 sec
closest planet: venus
time today: aprox 2-6 months, depending on orbital position
light speed: about two min.
Mars:
Today: 3 to 8 months, depending on orbits
light speed: aprox 2 min
closest star: alpha centauri
today(not really possible): aprox 10 to 50 years
light speed: aprox 4 years
closest galaxy: adromeda
today: Who the hell knows
light speed, over 100,000 years
the problem with traveling to other objects in space is that we dont have the technology for fast plausible propulsion. we have theory, but thats only good on paper. technically, we could get to mars in under a month, but the energy required to accelerate then decelerate is too much for us to deal with with current tech.

The closest thing in space is the Moon. It takes 3 days to get there. Mars is not nearly so close. It takes about 9 months to get there. The nearest star, Alpha Centauri, is really far. It would take many thousands of years to get there, even for the fastest space craft we have ever built.

Ditto Voyager 17 comments.
I couldn't have said it better myself. Remember though, technology is constantly moving forward, it is accelerating, and the rate of that acceleration is growing daily. What we know for a fact today could be considered "ignorance and superstition" tomorrow.
We will, someday, reach the stars and do it in less time than it takes light. We may not exceed the speed of light, we may warp space, bend time, or accomplish it by some means not yet dreamed of, but make no mistake, we will do it! Overcoming obstacles is the nature of Mankind and I don't see that nature changing anytime soon.

Mars about 3 to 6 months using an ion drive. To get to a star we'll have to improve technology considerably. At this stage (without worm holes or similar) we'd either need a multi generational ship or find some way to make cryogenic sleep work for the passengers.
The nearest star at 4.3 light year distance would be 43 years away, IF we could average 1/10th of light speed. At 1% of the speed of light you are looking at 430 years. Even at that low speed the amount of power needed is way beyond what we are capable of presently. 3,000 km/sec

closest planet is mars, takes 6-7 months of one way travel

relies upon on at what speed they shuttle, and whose body of reference you're searching at. Do you recommend with modern technologies? With modern technologies, an astronaut might want to die of previous age lengthy before he reached the celeb. for instance, the Voyager a million area probe hasn't even left the photo voltaic gadget yet, and this is been flying for 32 years. Now, if shall we shuttle at a hefty fraction of the speed of sunshine, the time might want to be shortened. Proxima Centauri is about 4.2 gentle years from Earth. What this implies is vacationing at close to the speed of sunshine, it's going to take over 4 years to attain. this can be technologically inconceivable for the foreseeable destiny. If shall we take care of 50% of the speed of sunshine, it really continues to be a huge stretch, it would want to take 8.4 years to attain Proxima Centauri. in spite of the undeniable fact that, for an astronaut contained in the spacecraft, time might want to bypass extra slowly as a results of time dilation. The astronaut might want to experience about 15% a lot less time. in accordance to the astronaut vacationing at 50% of the speed of sunshine, 7.27 years might want to have exceeded.

The closest thing from us is the moon. its about a month away i believe. the closest star would be the sun, that would take several dozens of years, even at light speed.

With current technology, it takes three days to get to the moon, about 19 months to get to Mars

About 2-3 years to get to Mars, which is where we sent the rover.

Been there -- done that. About three days. The moon.
