A day on Mars is almost the same as an Earth day. It is only 39.6minutes longer.
A day on Mars is about 24.6 hours. A year on Mars takes 687 Earth days.It takes Mars this long to orbit the sun.
Mars rotates on its axis at a slightly slower pace than Earth, with a day on Mars, known as a "sol," lasting about 24.6 hours. This means that a day on Mars is only slightly longer than a day on Earth, but Mars has a longer year due to its longer orbit around the sun.
1 day that is it
I like the "again"; one day the sun will expand to around the orbit of Mars, but not for many millions of years.
It takes 21 hours and 37 minutes to spin on its axis (a day) and 687 days to orbit the sun ( a year)
12 months or years.
By virtue of "Day". There is none or ever will be any "day" trips to Mars.
It takes Venus about 224.7 Earth days to orbit the Sun.
it takes 12 earth years
NASA has been planning around the idea of about 120 day one way trip.
