A light-year is not a measurement of time but of distance. How far light can travel in a year. Your question therefore asks about the distant between the Earth and Mars which varies with their orbiting about the sun.. However, Earth and Mars are never anywhere near a light year abart. At most, they are about 12 light minutes apart.
The best thing to travel in would be a space ship. It is a long way to the planet of Mars.
It would take about 9 years to travel from Earth to Jupiter, assuming a similar speed and trajectory as the trip from Earth to Mars. Jupiter is much farther away from Earth than Mars, so the journey would be significantly longer.
It is currently not possible to travel to Mars in a jet because jets are not capable of interplanetary travel. To reach Mars, spacecrafts like rovers or probes are used, which take several months to reach the planet depending on their specific trajectory and speed.
How long it takes a spacecraft to reach Mars depends on the changing distances between Mars and Earth as they orbit the sun, and other factors. Trips are usually planned for when Mars will be closest to Earth; the shortest is about three months. None of NASA's Space Shuttle fleet are capable of making the trip, and the remaining shuttles are due to be retired.
The time it takes for a probe to travel from Earth to Mars varies depending on their positions in their respective orbits at the time of launch. On average, it takes around 6-9 months for a probe to travel from Earth to Mars.

Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 lightyears away from Earth.
2 lightyears
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
It would take about 2.5 to 7 years to travel to Saturn, depending on the trajectory and speed of the spacecraft. On average, it takes about 7 months to travel to Mars with current technology.
One light year is around 10 trillion km or 6 trillion miles. Nine lightyears would be 90 trillion km or 54 trillion miles. You would generally just say nine lightyears though.
Travel time to Mars can vary depending on the positions of Earth and Mars in their orbits. On average, it takes about 6-9 months to travel to Mars using current spacecraft technology. Planning for the right launch window is important to minimize travel time.
It would take about 22.5 minutes.
It would take about 9 years to travel from Earth to Jupiter, assuming a similar speed and trajectory as the trip from Earth to Mars. Jupiter is much farther away from Earth than Mars, so the journey would be significantly longer.
From where ? ? ? From the sun: 12min 40sec From the earth when Mars is closest: 4min 21sec From the earth when Mars is farthest: 20min 59sec
a long time!
It would all depend on the speed travelling, as time = distance/speed.
