How many light years is a human?
Going at the same rate, it’s going to take you roughly 11.3 billion days to make a journey equivalent to one light-year. The average American human life is currently estimated at 78.74 years, which translates into 28,740 days. So you would have to live about 400,000 times longer than the average American to get there.
How long would it take to get to Mars?
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.
