Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 lightyears away from Earth.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
The time it takes to travel from outer space to Earth depends on the distance and speed of the spacecraft. Generally, it can take anywhere from a few hours to a few days to return to Earth from outer space.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
If you mean do any manned spacecraft use artificial gravity, the answer is, not so far. But, in the future, large spacecraft may create artificial gravity by rotating them. To conserve fuel, the gravity of the moon/planets is used to pull spacecraft toward them. And of course the gravity of earth is used to hold/pull on spacecraft so they orbit (circle) around it instead of flying off into space.

The Apollo spacecraft took 3 days to travel from the Earth to the moon.
22.2 minutes
It takes about 3 days for a spacecraft to travel from Earth to the moon. The exact time can vary depending on the speed and trajectory of the spacecraft.
It takes 3-4 days to get to the moon from Earth by spacecraft
Two Lightyears
It takes about 3 days (72 hours) for a spacecraft to travel from Earth to the Moon.
The travel time from Earth to Venus varies depending on the alignment of the two planets. On average, it takes about 3 to 4 months for a spacecraft to travel from Earth to Venus.
It takes about 3 days to get to the Moon from the earth.
9 years
Approx. 196 lightyears.
At the speed the Apollo spacecraft traveled, it took three to three and a half days.
