Because of the vastness of those distances, practical interstellar travel based on known physics would need to occur at a high percentage of the speed of light; even so, travel times would be long, at least decades and perhaps millennia or longer.
How long until we can travel space?
The first initial civilian space flight is planned for early 2022. Four people will fly to stay at the International Space Station for ten days. Space Adventures is one of the older space tourism companies and launched in 1998.
How fast can we travel in space with current technology?
The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph. It would take just 20 seconds to go from Los Angeles to New York City at that speed, but it would take the solar probe about 6,633 years to reach Earth's nearest neighboring solar system.
How long is 1 hour in space?
Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.

The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970. This record has stood untouched for over 50 years!
Do you age slower in space?
We all measure our experience in space-time differently. That's because space-time isn't flat — it's curved, and it can be warped by matter and energy. ... And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.
What does space smell like?
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous."

The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
Can I jump off the moon?
Although you can jump very high on the moon, you'll be happy to know that there's no need to worry about jumping all the way off into space. In fact, you'd need to be going very fast – more than 2 kilometres per second – to escape from the moon's surface.
