Different aircraft had different speeds, and the time needed to fly 5000 light years was also different. For example, the New Horizon probe's speed was about 58,000 kilometers per hour, and one light year was about 9.46 trillion kilometers. According to time = distance/speed, it would take about 17,751.3488 years to fly one light year, so it would take about 88,756,744 years to fly 5000 light years. The speed of Voyager 1 was 16.9 kilometers per second when it was about 152 astronomical units away from the sun. It took about 17,700 years to fly 1 light-year and about 88.5 million years to fly 5000 light-years. It would take an ordinary plane 1.2 million years to fly 1 light-year, and 600 million years to fly 5000 light-years. And if the spaceship traveled at a speed of 10 kilometers per second, it would take 30,000 years to travel 1 light year, and 150 million years to travel 5000 light years.

A rocket would take about 30,000 years to fly.
Different spaceships would take different amounts of time to travel one light year. If the Voyager 1 probe is currently about 17.062 km/s,(61452 km/h, about 538 million km/h per year), it takes more than 17500 years to fly 1 light-year. The New Horizon probe launched in 2006 has a maximum speed of 23.33 km/s.(84000 km/h), it would take more than 12800 years to fly 1 light year at its speed. Assuming that there was a solar sail spacecraft that could reach one-fifth of the speed of light (60,000 km/s), it would only take 5 years to fly 1 light year. And with the speed of common human transportation, such as walking (5 kilometers per hour), running,(44.72 kilometers per hour, the fastest human record), driving (60 kilometers per hour), taking the high-speed rail (300 kilometers per hour), and taking the plane (900 kilometers per hour). It would take 216 million years, 24 million years, 18 million years, 3.6 million years, and 1.2 million years to complete a light-year distance. At these speeds, it was impossible to complete a light-year journey within the lifespan of humans. The novel "Hundred Years of Spaceship" is equally exciting.

One light year was about 9.46 trillion kilometers. As for how long it would take to fly, it depended on the speed. For example, the current speed of Voyager 1 was about 17 kilometers per second. It would take about 17,000 years to fly at this speed. If the speed of the spaceship was one light year per second, then it would only take one second to fly one light year. Different speeds would result in a huge difference in the time needed to fly a light year. At present, the speed of human aircraft was still far from the speed of light (about 300,000 kilometers per second). The novel "Hundred Years of Spaceship" is equally exciting.

If one were to fly at the speed of light, according to the definition of light years (the distance of one year for light to travel in a straight line in the vacuum of the universe), it would take 500 million years to reach a place 500 million light years away. However, if the speed of the spaceship was lower than the speed of light, it would take longer to reach there. The exact time depended on the speed of the spaceship.
